Urea is an effective granulated mineral fertilizer with a wide spectrum of action. The second name for urea is carbamide. Its value for tomatoes is due to the high content of the most important nutrient element, nitrogen in easily digestible form. Urea is recognized as one of the most highly concentrated, nitrogen fertilizers. The proportion of nitrogen in it is 46.2%. Fertilizer applied to the soil comes in contact with enzymes produced by bacteria in the soil. In the course of this reaction, urea is converted to ammonium carbonate in a short time.
The best results are given by the application of this fertilizer for all types of soil. The main condition for the effective operation of urea is considered to be immediately incorporated into the soil, so the loss of ammonium carbonate will be minimal. With the correct introduction of urea plants respond good development and abundant fruiting. Fertilizer is widely used by gardeners. The popularity of urea is due to two more factors: it is sold in all specialized stores at affordable prices.
The use of urea for tomatoes
Tomatoes belong to capricious and capricious culture. The most important step in caring for tomatoes is proper fertilization. Phosphorus, potassium and nitrogen - the most necessary trace elements for tomatoes. Each work has its own purpose. Phosphorus increases seedling tolerance to adverse conditions. Potassium is required for the ripening of fruits, prevents their disease. Nitrogen activates the growth and development of tomatoes, strengthens the immune system, increases productivity. In each period of growth, tomato seedlings need different fertilizing with fertilizers with an appropriate set of trace elements.
Urea, as the main nitrogenous fertilizer, is used in the garden for tomato as a top dressing. The use of urea for fertilizing is necessary during the cultivation of seedlings from seeds, fertilizer optimizes the growth and harmonious development of the tomato seedling and its root system. Top dressing of tomatoes with urea includes the processes of vegetation of tomato seedlings, seedlings are developing correctly.
When to conduct root dressings
At the stage of nursing seedlings urea for feeding tomato plays an important role. Plants should develop a strong root system with a well-formed green mass. Lack of nitrogen will negatively affect the development of tomatoes. How to determine that the seedling needs additional feeding? The main symptom is slow growth, thin weak stems. Another sign is yellowing of leaves, their deformation and falling off. Nitrogen starvation will also result in falling floral brushes. This, in turn, will negatively affect the formation of ovaries and fruits.
With an excess of nitrogen there will be an excessive increase in the green mass of the bush to the detriment of the fruiting function. The bush will give a poor-quality harvest. Frequent use of urea, over measure also leads to the appearance of fungal plant diseases.
Feeding tomatoes with urea is made according to the generally accepted scheme:
- Tomato seedlings need to be first fed after the appearance of 2–3 true leaves, provided that the seeds have been properly treated and the soil for planting has been prepared correctly,
- The second feeding is needed 7–8 days after planting the tomatoes in a permanent place. It should be borne in mind that fertilizing from urea immediately after transplanting seedlings into open ground harm plants. The strength of the seedling goes on building a leaf apparatus, and not on the formation of ovaries,
- the third top dressing with carbamide is envisaged in 2–3 weeks, not earlier, since the introduction of nitrogen will provoke a rapid growth of green mass to the detriment of fruit bearing. Agronomists advise to conduct a comprehensive feeding, for this 1 tbsp. spoon fertilizer must be diluted in a solution of infusion of manure. It must be borne in mind that during the mass flowering of tomato plants, the use of urea in the garden should be stopped, because there will be a buildup of green mass to the detriment of tying inflorescences,
- The fourth dressing will be needed according to the situation, if the flower brushes are not tied or fall. The effect will give the addition of trace elements in the urea solution. Potassium permanganate can be added to the urea solution,
- the last time you need to make water at the beginning of ripening tomatoes. Accelerate the ripening of fruits by watering with a solution of urea, potassium sulfate, and potassium magnesium in a proportion of 3 g per 10 l of water. Pour the bushes under the root, powder ashes.
Agrotechnical regulations provide for the use of carbamide no more than 5 times per season when depleted soils in the garden plot. The last two feedings need to be done as needed. Urea, as a fertilizer, oxidizes the earth. To neutralize, you can make wood ash, bird droppings, limestone, superphosphate.
Observation tells about the needs of plants in one or another element. The leaves turn yellow with a nitrogen deficiency, turn purple from a lack of phosphorus, pale with green veins talk about the lack of iron.
Urea Solution Preparation Rules
There are tips on the introduction of urea in granules directly into the soil before planting a tomato or in the wells when planting seedlings. In this case, the fertilizer quickly dissolves in the soil, useful elements evaporate. For the same reason, it is pointless to scatter urea on the soil. Agronomists are questioned by such procedures. Urea is easily soluble in water, therefore, its use in the garden as a solution is more effective for plants.
How to dilute urea to feed the tomatoes correctly in order to achieve the maximum effect and get a high-quality fruit harvest? According to the instructions, urea, as a fertilizer, at a rate of consumption is 25 g per 1 square meter in the cultivation of tomatoes. This amount is diluted in 10 liters of water. In the resulting composition, you can add a complex of trace elements. Water the seedlings under the root at the rate of 1 liter per tomato bush. After the drug is applied, it is necessary to mulch the stem of the seedling to avoid the loss of useful elements.
Nutrients enter plants not only through the roots, but also through the leaves. The sparing effect of urea on the leaf apparatus allows, with a lack of nitrogen, it is harmless to plants to perform foliar dressing. How to dilute urea to feed a tomato? Prepare a working solution according to the instructions at the rate of 50 g per 10-liter bucket of water. Many gardeners consider this dose to be excessive and make the solution less concentrated. Spraying of plants produced using a spray gun in early June.
For watering and fertilizing it is necessary to use water of a comfortable temperature. Cold water can provoke powdery mildew and late blight. It is recommended to plan a foliar top dressing with urea solution in cloudy weather in the evening, so that in the morning it is better absorbed with dew. Urea, as a fertilizer, in application for tomatoes, has favorable properties. The task of foliar spraying is to obtain a faster effect that positively influences the development and appearance of the plants.
Proper use of urea to feed tomatoes will solve many agrotechnical problems. In order for the fertilizer to benefit the plants, you need to remember that working with chemical fertilizer is necessary according to the instructions. Exceeding the recommended dosage is as dangerous as its drawback.
Video, the use of urea in the garden:
For the proper cultivation of tomatoes, you need to prepare the soil in autumn. Manure and humus are used as fertilizer for the soil. Also, the soil must be fertilized with phosphate or potash fertilizers.
Basic fertilizers for soil:
- Potassium salt
Any seedlings must receive the necessary fertilizer.and tomato is no exception. By the appearance of a seedling, you can easily determine its condition and determine the lack of a certain nutrient:
- If the seedlings do not grow, while the leaves on the bush fade, then this means that nitrogen is needed.
- If the reverse process occurs and the seedlings grow into a huge bush in a small amount of time, then the amount of nitrogen should be reduced.
- If the leaves of the seedlings become purple, then this indicates a lack of phosphorus. If the reverse process occurs, namely the leaves fall, then phosphorus should be added as a fertilizer.
- If the leaves of tomatoes begin to curl very quickly, this means that more potassium and nitrogen are needed, and also less use of phosphorus.
Tomato gets almost all fertilizers through its roots, namely, through the root system. In this case, all the fertilizer should be applied only through the soil and nothing else. The amount of fertilizer must be determined depending on how the tomatoes grow on the bush or the weather.
Fertilizer for tomatoes
All fertilizers that are necessary for feeding tomatoes are divided into two huge groups. So, inorganic substances can be attributed to mineral fertilizers. Their advantages:
- Getting an accelerated effect
- Low cost
- Easy transportation
Urea is nitrogenous fertilizer.. Urea is fed if the tomatoes lack nitrogen. Urea is one of the best means in the feed of tomatoes. Potassium fertilizers include potassium sulfate. It will help with the feeding of tomato due to the presence in its composition of sulfuric acid salt.
From organic fertilizers, manure, peat or compost will be the best choice when feeding. Such fertilizers are needed for accelerated growth of tomatoes.
A type of feeding
Feed bushes of tomato can be only in two ways:
- Top dressing tomato. It consists in watering with water mixed with fertilizers under the very root of the bush. It should be borne in mind that the solution should not fall on the leaves of the bush - this leads to a burn.
- Foliar top dressing tomato. Foliar top dressing of tomatoes consists in watering the leaves of the bush. However, it should be borne in mind that the concentration of the solution should be significantly lower than with the root method. Unroot method, unlike the root, will help to quickly supply the seedling with all the necessary minerals and nutrients. It is necessary to spray bushes very often, but in small doses. At the same time it is desirable to use rainwater, but not chlorinated.
Top dressing of tomato seedlings
The first time to feed the tomato seedlings need only then when the first leaves appeared. Fertilize need urea. The first top dressing tomato is very important.
The second feeding should be done after one week and should be already fed with droppings, preferably with birds. The litter should be diluted with water and allowed to brew for about two days, and then diluted ten times more. Such a solution will be able to give excellent growth of a sapling.
Before planting a seedling in the ground, for a week you need to feed it with ashes. So the sapling can settle down better in the ground and will not perish.
How to understand that tomato seedlings need feeding?
For fertilizing seedlings of tomatoes, ready-made purchased fertilizers are used, and they are prepared by hand according to popular recipes at home. The composition is selected depending on the objectives: to stimulate the growth of shoots, in order to prevent diseases, to enrich the nutrients that contribute to the normal growing season. To determine the shortage of any micro or macro elements, you just need to look at the plant, it itself gives a hint:
- If felt iron deficiency, then the leaves become pale, and the green streaks are clearly pronounced.
- With slow growthmost likely not enough nitrogen fertilizers. They will help to restore withering and dried shoots.
- When appearance of purple hue, use phosphorus based supplements.
- Leaves turn white and deform more often when calcium deficiency occurs.
- If on fruit dark spots appeared, then most likely the problem is lack of calcium. At the same time spotting on other parts of the plant is absent.
- When you stop the growth of escape There is a lack of magnesium and potassium.
Useful feed for tomato seedlings in greenhouses and open field
Tomatoes for full growth and abundant fruiting requires a variety of feeding, containing a specific set of trace elements:
In addition to the main components, complex tools include: calcium, copper, iron, zinc and other substances.
Urea: fertilizer plants after planting
Urea (carbamide) is a white granules. Fertilizer supplies the plant with nitrogen, soil bacteria react with the substance, transforming the main component into ammonium carbonate. The formed product partially evaporates, which eliminates the effect of accumulation of the compound in the fruit.
How to use urea when planting a tomato? A feature of the use of urea is moisture soil before sprinkling. If this is not possible, then the added supplement must be covered with a small layer of soil. Per square meter consumed 10-15 grams. facilities. At cultivation of solutions on a bucket of water add 20-30 gr.
Advantages of urea:
- substance completely soluble in water,
- when properly applied eliminating the accumulation of nitrates in the soil and fruits,
- accelerated buildup vegetative mass,
- acts as a means of struggle and prevention from insects and diseases.
When working with urea should consider some of the nuances:
- for preparation of working solution warm water is used (the reaction during the dissolution reduces the temperature of the liquid, the tomatoes under watering will be stressed)
- a lot fertilizer can burn plants (in order not to damage the shoots, sodium sulphate must be added to the solution).
The use of urea for fertilizing after planting tomatoes is useful because the seedlings are more durable due to the strengthening of the immune system. At an early stage, seedlings are actively increasing the green mass, and the root system is developing well.
Wood ash application
Wood ash is considered one of the most affordable fertilizers, rich in minerals. However, do not use it uncontrollably. To determine the dosage, the type of cultivated crop and the type of soil are taken into account.
The chemical composition of the ash includes the following substances useful for tomatoes: phosphorus, magnesium, potassium, calcium, sodium, etc. Nutritional components play an important role in photosynthesis, increase plant resistance to diseases and pests, contribute to the better development of the root system, prolong the fruiting period.
Tomatoes ash ash
How to fertilize the plant with ashes, how to properly dilute the infusion and water?
- for cooking dissolve 200 gr. ash in a bucket of water and insist 1-2 days,
- when spraying 200-300 grams are applied to the soil. on 1 m2,
- for breeding solution on a bucket of water take 100 grams.
The advantages of wood ash:
- affordable and inexpensive way fertilize the beds,
- is used as food and the prevention of certain diseases and pests,
- you can apply in several ways - dusting, spraying, watering at the root,
- security facilities.
The disadvantage is the short-term effect of wood ash-based products; therefore, the procedures and treatments are repeated several times.
Nettle: how to insist and water
Gardeners use nettle along with wood ash and urea to replenish nutrient reserves. Its main advantage is naturalness and safety, which is important for obtaining an environmentally friendly harvest. The burning plant is saturated with nitrogen compounds. The composition is also rich in valuable minerals and trace elements such as: potassium, magnesium, iron, vitamins A, E, B, K, carbon compounds, etc.
The benefits of using tomatoes as fertilizer are as follows:
- stimulates growth young shoots
- renders bracing effect, increases resistance to diseases and pests,
- destroys aphids in steady hot weather,
- promotes green mass seedlings.
To obtain a good harvest of tomatoes and other crops of the family of bowlings, it is recommended to combine nettle infusions with the use of mineral tukas. The alternation of such dressings will provide tomatoes with all the necessary nutrients.
Advantages of nettle based products:
- soil restoration, enrichment with micronutrients,
- available raw materials
- safety of use
- complex effects on tomatoes.
There are practically no shortages of nettle, unless it is necessary to tinker with collecting herbs and preparing infusions.
Among gardeners, fertilizers for feed based on nettle are very popular. Of the most simple but effective recipes, the following options of infusions are highlighted.
Fill a large container with freshly picked grass and pour cold water over it until the liquid covers it completely. Тару накрывают крышкой и оставляют содержимое на несколько недель (до момента, когда начнётся процесс брожения). Не менее 2-х раз в неделю необходимо перемешивать зелье.
High temperature contributes to rapid fermentation, so the tank needs to be installed under direct sunlight. Also, gardeners add fermentation catalysts (yeast or fertilizer Baikal) to the mixture. After the appearance of persistent ammonia aroma and thick foam, the infusion can be supplemented with a sprig of valerian and wood ash. It neutralizes the stench.
End of fermentation is expressed in reduced gas formation and the disappearance of foam. The resulting liquid is filtered through gauze, folded in 2-3 layers. Green fertilizer is diluted with water: for foliar dressing 1:20, for watering 1:10. This solution can feed not only tomato bushes, but also cucumbers, peppers and strawberries.
Crushed nettle plants, wormwood, dandelion and yarrow into a plastic container, fill it with water and cover with a lid. Leave for 10 days in the sun. After the start of fermentation add ½ tsp. yeast and give the infusion to ferment until the formation of bubbles. The resulting liquid is passed through a strainer or gauze layer, diluted with water in a ratio of 1:10.
Add ground crushed green nettle to a non-metallic container, add crushed bread and a bag of dry baker's yeast. Cover with water at room temperature and cover the container with a lid. After 5 days, the potion will be ready. After filtering it will be necessary only to dilute the concentrated fertilizer with water in the proportion of 1:10 and water the plants.
Fertilizer options for seedlings are actually more, in the article examples of only the most popular and affordable nutritional formulations. For many years of practice growing tomatoes each gardener acquires his own practices and recipes, adapted to certain conditions (for greenhouses or open ground) and varieties.
Planting algorithm sapling
It is necessary to feed the sapling after it has been planted in the ground. For the season you need top dressing produce about four times.
The first feeding of tomatoes is one of the most important in the formation of the seedling. In order for the seedling to form roots and the seedling can finally take root in the ground, it is necessary to use phosphate and potash fertilizers. It should be borne in mind that the amount of nitrogen should be small, since the bush will grow rapidly, which will lead to immediate greening, but will not provide a large amount of crop.
However, mineral fertilizers can be replaced by:
- Ash. It contains the necessary elements that are necessary for tomatoes.
- Manure and litter. Such supplements will help create a larger crop by the end of the ripening of the seedling.
- Infusions. In addition to the usual dressings, you can use liquid fertilizers. An excellent choice would be infusions of herbs or young nettle. They contain the necessary trace elements for tomatoes, such as potassium, nitrogen and iron.
However, it is up to the gardener to decide which fertilizers to feed their saplings with.
Very often, instead of the standard dressings, experienced gardeners use folk remedies as a top dressing tomato. One of these is the eggshell.. Making such dressing is very simple. The eggshell is first finely ground, then poured with two liters of water and infused until the smell of hydrogen sulfide appears. Before using the solution is further diluted with water.
Another popular remedy is yeast. Their advantages:
- The land in the seedlings is enriched with the necessary microflora
- Roots of seedlings become stronger and harder.
- Seedlings tomato copes with any disease
It is very simple to prepare such a solution.. For one bucket of warm water, take a pack of yeast and 2 spoons of sugar. This solution is added only under the seedling root. Such top dressing can be combined with ashes or grassy infusion. This combination should be fed at least twice during the summer period.
It is also easy to prepare and a solution of herbs. In a large volume, preferably in a barrel, grass is folded, you can add a little nettle to it and fill it with water. To speed up the process, you need to add some sugar. After this, it is necessary to leave the barrel until the solution ferments. And already before using such a solution, it is necessary to dilute it with water to prevent burns.
In the people this period is called the term of the second feeding. During this period, you should use a solution of iodine in water. Thanks to iodine protection against fungal diseases.
If a tomato seedling is very weak and, at the same time, there is a slow process of ripening of the leaves, then need to use top-dressing tomatoes:
- Onion Husk Blend
- Calcium Nitric Acid Solution
- Dilution of potassium permanganate with water
- Use of superphosphate
- Iodine solution
- Use of copper sulfate
It is important to consider that when using all the solutions, before use you need to dilute with water.
Also experienced gardeners recommend using several components as a feed. Such combinations will help to simultaneously enrich the seedlings with all the necessary minerals, improve the growth of the tomato, and also strengthen the leaves.
Proper feeding tomato
When providing a tomato dressing it is important to know certain rules in order to do not harm seedlings:
- Any solution must be diluted with water.
- Do not neglect a large amount of organic matter.
- Any top dressing tomato should be carried out only in the evening. This will give the best effect.
- You should know what to use fertilizers, so as not to burn the leaves of the seedling.
- Before feeding under the root, you need to water the soil in advance.
Top dressing tomato in the greenhouse
Starting to feed the tomatoes in the greenhouse need only after 20 days after their transplant. As a solution, you should use a mixture of urea and potassium sulfate. The mixture is diluted in water in the ratio of 1 to 300. For each seedling in the greenhouse, you need to use one liter of this solution.
The next time you need to feed the tomatoes only after flowering. Fertilizing seedlings is necessary in order to form the necessary thickets that will yield. The solution used is a mixture of potash fertilizer, litter and manure. For 10 liters of water you need 0.5 liters of litter, manure and a spoon of potash fertilizer. For each seedling in the greenhouse consumes about one liter of this solution.
After the formation of the ovaries occurs, need to feed a mixture of ash and boric acid. 10 liters of used 2 kg of ash and 10 grams of boric acid. Before use, the solution must be infused at least a day. On one seedling in the greenhouse you need about one liter of solution.
The time for feeding a tomato depends on the season, weather, the composition of the earth, the state and place of the seedlings. Each gardener chooses himself when he needs to feed the seedlings and in what way: root or foliar. In order to get a large amount of tasty harvest at the end of the season, you need to properly feed the seedlings with all the necessary nutrients.
Why do you need to fertilize tomatoes?
For growth and fruiting culture needs 3 main elements:
To feed the tomato seedlings at first after planting in open ground, choose nitrogen fertilizers. They provide the rapid growth of the root system and the ground green part of the plant.
Lack of nitrogen in the soil immediately affects the appearance of tomatoes:
- Stems look thin, weak, brittle.
- Leaves turn yellow and fall off.
- The plant fades and withers.
- Ovaries die off.
Be careful: these same symptoms indicate not only low nitrogen levels, but also excessive watering and too low temperatures in the greenhouse, which, in turn, provoke root decay.
Tomatoes very quickly pull out all the minerals from the soil. Also, nitrogen is easily washed out of the soil with melt water. Therefore, the feeding of tomato seedlings at first (from the moment of planting until the formation of the ovaries) should take place regularly.
Best Nitrogen Fertilizer - Urea
Urea or carbamide fertilizer is considered the most effective nitrogen source.
The following characteristics speak in his favor:
- High digestibility. Pure urea contains more than 40% nitrogen, which is much higher than other fertilizers. That is why its use is so popular among both professional farmers and gardeners amateurs.
- Availability. Urea can be found at any garden store.
- Low price.
Externally, urea is a white or grayish, odorless granules, which easily dissolve in water, especially warm. It is used for both root and foliar supplements, and also helps to combat insect pests.
As a nitrogen fertilizing of tomatoes, urea has an indisputable advantage - it is not as aggressive, it does not burn the leaves, as does ammonium nitrate, for example. However, overdose of nitrogen is very dangerous: too frequent use of urea can ruin the culture. An excess of nitrogen is dangerous, in particular, the fact that the plant is too active in growth, but does not form the ovary. In addition, the risk of fungal infection increases.
Therefore, urea must be made, observing all the necessary proportions.
Instructions for use
So, for tomato seedlings, urea must be diluted in water or mixed with other types of fertilizers. For 1 m², 25 g of granules or powder will be needed, which must be added to 10 liters of water. To feed the seedlings, just planted in the ground, for each tomato bush is worth spending about 1 liter of solution. This will accelerate the growth of landings.
Urea oxidizes the soil, so it should be neutralized. For this purpose, it is reasonable to use limestone, it is added to the solution in the following proportions: 15 g of urea and 8 g of limestone per 1 m² of beds.
Top-dressing of tomatoes during the growth period is carried out according to the following scheme: 100 g of urea powder per 10 liters of water. Urea can be mixed with neutralized monophosphate. In this case, the fertilizer promotes the activation of vegetative functions and enhances flowering.
The third feeding of seedlings should take place not earlier than in 2-3 weeks to prevent an excess of nitrogen in the soil. The plant is best watered with a solution in the evening, when the sun is no longer so active, or in cloudy weather. Before making fertilizer, tomatoes should be poured with plain water so as not to burn the root system.
The fourth and fifth tomato top dressing is carried out according to the situation - only if the plant needs it (for example, the inflorescences fall or the bush looks overly weak). After the formation of ovaries, urea should not be applied, otherwise the plant will spend forces on the growth of lateral shoots, which, of course, will affect the size and taste of the fruit.
So, urea is a very effective fertilizer for tomatoes, but should be used with a certain amount of care. Try to keep the solution from watering on the leaves, especially young ones, as this will most likely cause a burn.
To avoid an overdose, many gardeners prefer to feed the seedlings in a foliar way, that is, by spraying with a weakly concentrated solution (1 tablespoon of granules per bucket of water).
Regular feeding of tomatoes with nitrogen fertilizers has a good effect on the appearance of the plant (the bush becomes more lush and green), but phosphorus is more necessary for good fruiting.
Root or foliar dressing
There is another gradation - root species are introduced into the soil and extracted from it by the roots, and non-root species are sprayed on the leaves and trunk. The choice of how to feed the plants within these two types of decisions is based on the fact that foliar fertilizer is absorbed and absorbed very quickly, becoming an urgent help weakened tomatoes, while root fertilizers are designed for a long period of action.
You can combine both of these types of dressing to achieve the highest yields. Both types can be used in open and closed grounds, bringing many benefits.
The foliar top dressing is sprayed onto the plants by means of a sprayer. In this case, completely soluble or initially liquid products are used in a low concentration, since with its increase there is a risk of burning the plant.
Greenhouse or open ground
A different approach may also suggest feeding tomatoes in the greenhouse and in the open field. When planting in the greenhouse, many gardeners avoid preliminary fertilization at the root, making it only after two weeks. Such an approach allows the injured root system to heal.
Potash and nitrogenous fertilizers applied to the soil are used as fertilizers in order to eliminate in advance the risk of deficiency of these elements, which are vital for the successful development and fruiting of tomatoes. Organic fertilizers, such as urea or manure, are also relevant from the very first weeks of planting plants in the greenhouse.
And if planting is conducted in open ground, in any case it is reasonable to fertilize it in advance, preparing it for plants. Since tomatoes “love” nutritious fertile soils, many gardeners begin to prepare open ground for planting since the fall, thinking in advance about how to fertilize plants.
Initially, you should prepare the soil, checking its pH, which ideally should have a slightly acid indicator. Since autumn, the soil is loosened, freed from rhizomes, it can be applied humus and other organic fertilizers. In the spring, you can make mineral dressing, preparing the soil - planting tomatoes in cold soil is still impossible, and the gardener will have time to prepare it.
For growing tomatoes on the street, you can use superphosphate, reviews of it are traditionally given positive. As a foliar application, you can use a solution of urea in a small concentration, which is especially useful before flowering. It can also be recommended when growing plants in a greenhouse.
At what stage to fertilize
Seasonality is taken into account first of all. Autumn is a good time to prepare the soil for planned plantings, at this time it is necessary to apply fertilizers of natural origin: manure, droppings or humus, up to 6-8 kg per square meter. In the spring, nitrogen fertilizer, urea or superphosphate, and potassium chloride should be added. In the spring, greenhouses can make a small amount of manure, biohumus or complex fertilizers.
In different periods of their life, tomatoes require different feeding. It should be noted such milestones, important for the gardener:
- Before sowing seeds, they can be maintained in growth stimulants. Zircon or Baikal are well suited for this purpose, or you can use wood ash.
- When sowing, you can add 8 g of urea to the bucket of the earth, 40 g of superphosphate, which will have a beneficial effect on the development of seedlings.
- At the time of landing in the pots, you can apply 20 g of superphosphate and 12 g of urea per 10 liters of soil. After two weeks it is worth repeating top-dressing, having doubled the dose of superphosphate and reduced the amount of urea applied in the same amount. In between, sprouts can be treated with foliar top dressing, Energin and others will suit.
- Planting should be carried out in the soil, pre-fertilized with organic matter, which well stimulates the growth of greenery. Further feeding is carried out after 2 weeks, and then alternating about 10 days in the open ground and once a month in the closed.
- Before flowering phosphates are introduced, in the process of flowering it is worth sprinkling growth stimulants.
Tomato fertilizer with ash
Wood ash is one of the best fertilizers for tomatoes throughout the life of the plant. It provides a growth of greenery during the growing season, and at the same time does not threaten to burn the plant, because many gardeners recommend simply sprinkle it around the stem. Ash is needed in large volumes than for other plant species, it gives the necessary phosphorus, calcium and potassium to a tomato, and does not threaten with excess nitrogen, which can make the fruit loose and soft.
This cheap and affordable fertilizer can be used continuously, in a volume of 0.5 - 1 kg per square meter, in acidic soils - more, in alkaline - less. You can use an aqueous solution of ash - 100 gr. 10 liters, and spray them with a plant. Top dressing should be carried out once in two weeks. Feeding with ashes is a traditional productive solution.
Chicken and other manure fertilizer
Another highly effective solution available in rural areas is fertilization of plants with chicken manure. If you decide to use folk remedies, you can also consider for this purpose pigeon droppings, mullein, even horse manure - all these types of fertilizers are used in approximately the same way. You can make a liquid fertilizer, diluting the litter with water in a ratio of 1:20 and standing it for about 10 days. Pour this mixture only aisle.
You can create compost if you put grass litter in the fall, then in the spring you will have first-class fertilizer, also for use between rows. Pure litter is not worth making. The correct approach to its use allows you to make the land fertile for 3 years ahead.
A well-known popular method is to feed tomatoes with yeast. They are made at the root of no more than 2-3 times in all time, mainly during the development of seedlings and vegetation. В дрожжах содержится широкий набор минералов, полезных для растения, и способствующих хорошему развитию корневой системы и листвы. Первый раз стоит внести подкормку в период выращивания рассады, во второй – на момент завязывания бутонов, примерно на четвертую неделю после высадки в постоянный грунт.
For feeding, a kilogram of live yeast is taken and placed in 5 liters of warm water for a day. A day later, the mixture is diluted in the proportion of half a liter per 10 liters of water.
Urea Use as Fertilizer
It is possible and necessary to fertilize tomatoes with urea, this fertilizer is recommended by many gardeners. Buying fertilizer costs in granules, distributing it to 20 grams. per square meter of planting in open ground. Someone puts it on a tablespoon in each well, and after that does not use other fertilizers all summer. In greenhouses this tool is not recommended.
Many gardeners are also advised to use urea for foliar treatment, its weak solution can be applied once a month. There are different recipes and concentrations, each gardener develops his own recommendations, and the main task is not to burn the plant.
How to feed tomatoes with iodine
Feeding with iodine is another promising approach in which fertilizer is applied once every two weeks. 10 grams of iodine diluted in 10 liters of water, often adding 10 grams of phosphorus, up to 20 grams of potassium. The plants are watered with this water, adding half a liter to each root.
Watering tomatoes is necessary just under the root of each bush, especially if watering is carried out with additives. This plant loves water, it can not be overdried, and if we ignore such recommendations for watering, you can generally lose the crop. This is especially true of dry seasons.
Mixed Tomato Blends
On sale you can find a wide list of complex mixtures, which are recommended for feeding the tomatoes, or solanaceae in general, or tomatoes and a number of other plants of other families. You can use such tools, as they will immediately compensate for the lack of a wide range of useful substances. In addition, each of the complexes is accompanied by its own instructions for use, which simplifies handling.
A proven option is the Agricola complex, which accelerates the growth of plants during the growing season and leads to an increase in yield. A good option is also Sudarushka, which will provide a lot of ovaries and abundant fruiting.
Growing tomatoes, it is necessary to remember that these plants are sensitive to fertilizers, and it is impossible to overdo it with top dressing. A small flaw will be better than overshooting. In addition to fertilizers, do not forget about other ways to increase the yield of this crop - plant it after legumes, and exclude its planting after potatoes and other solanaceous. A rich harvest will be the best reward for your efforts.
