How can you feed tomato seedlings?
Own personal plot makes it possible to stock up for the winter, which then significantly save the family budget from unnecessary costs. Your own fruits and vegetables are much healthier, but a gardener has to work hard to get high-quality fruits. High-quality planting material can guarantee a big harvest, so it is grown from seeds at home on its own.
Why is additional nutrition needed?
In order for tomatoes to be strong, with healthy foliage and a thick stem, they need little watering and give them enough light. Pale leaves, weak, thin tops signal insufficient intake of nutrients. In this case, resort to additional feeding.
It is possible to grow high-quality tomato seedlings on a home windowsill, it is enough to study the features of applying selected fertilizers. The formation of shoots is monitored from the very moment when the seed germinated and a small sprout appeared on the surface of the soil. If you feed the bush in time, then by the time it is planted in the ground it will become healthy and strong.
Plants require essential nutrients throughout their life cycle to grow and develop. Many of these can be found in the soil, but often in insufficient quantities to sustain high yields.Soil and climatic conditions can also limit the uptake of essential elements by plants at key growth stages. Tomatoes require 13 essential minerals that play a number of key roles. If any of these are missing, plant growth and crops suffer.
Gardeners often control crop yields by feeding plants what they need in an environment protected from soil and weather changes. In all situations, it is important that the composition and amount of fertilizer match the needs of the tomato.
Of the secondary nutrients needed at the initial levels, calcium can be noted, which strengthens the cells of the plant and prevents the occurrence of various fruit diseases. Healthy fruits that receive the element in the required amount are less susceptible to damage and have a longer shelf life. Vegetables containing a high percentage of calcium are of great value for human health. Eating fresh, thick-skinned tomatoes will help us get the calcium we need for strong bones.
Sulfur is an integral part of many amino acids and proteins. Micronutrients strengthen and accelerate the growth of bushes, provide them with primary and secondary nutrients. Manganese, iron and copper affect photosynthesis, the process by which plants use sunlight to grow. Boron is necessary for the development of shoots and roots and is very important during flowering and fruiting. Zinc is essential for the production of important phytohormones.
Professional gardeners use not only organic, but also mineral fertilizers. Very rarely a plant can grow healthy without top dressing, more often there is a pale green small foliage that turns yellow over time.Such seedlings always grow poorly and subsequently give a meager harvest, thereby the gardener invests his own strength in vain.
It is best to use a special soil when sowing tomato seeds, which already contains the necessary components, including nutritional supplements. Plants in this case will need fertilizer only after planting in open ground, so that they can get stronger and strengthen their root system in the ground.
Since ancient times, folk remedies have been used, and professionals advised beginners to prepare beds in advance, long before seedlings are planted in them. Until it gets cold, in the area where it is planned to make a tomato plantation in the future, it is necessary to decompose the humus, you can use the humus mass. Actively added to the ground:
- dolomite flour;
- peat;
- wood shavings;
- lime.
You can’t just fertilize without understanding what exactly the plant lacks. The appearance of a tomato clearly demonstrates the lack of one of the necessary elements in the soil. If the foliage of tomato seedlings stops growing abruptly, begins to turn pale and even becomes stained, it's definitely time to think about adding nitrogen to the soil. But if you overdo it with the additive, you can get lush foliage and a small amount of fruits as a result, which also harms the gardener.
Not a single plant can do without phosphorus, but its excess leads to the fact that the foliage begins to fall off, turns yellow. We noticed a purple tint on tomato leaves, which means that this element is not enough. An excess of phosphorus, combined with a lack of nitrogen and potassium, leads to twisting of tomato leaves.
Every gardener who treats his work with great responsibility and wants to get a healthy big harvest must strictly monitor the time of feeding and its quantity. In this case, the more the better - this is a misjudgment: an overabundance of minerals in the soil can worsen the situation.
Professional gardeners do not recommend fertilizing before the first leaves appear. At this stage of development, the plant directs all its forces to strengthening the root system, you only need to help it in this. As finished products are used:
- "Fortress";
- "Nitrophoska";
- Agricola Forward.
All products are complexes of the elements necessary for the tomato. The first watering is more concentrated, subsequent solutions are diluted weaker. Ten days after the first feeding, you can repeat it and add manganese to the water. Superphosphate solution helps to achieve thick and strong stems with healthy dark green foliage. It has already been proven by experience that the introduction of additional feeding increases the yield up to three times.
When is it not necessary to fertilize?
There are also cases when the plant does not need fertilizer. If you follow certain rules, you can avoid problems in the future. For example, you should not use anything within two weeks after picking. It is enough to make a serum from potassium sulfide and superphosphate to support the plant during this period. It is enough to add a tablespoon of each component to a bucket of water.
Some prefer to replace this solution with nitroammophos, which can be used again two weeks after the first watering. Before transplanting into the ground, seedlings should be watered fifteen days in advance and no later.
It is not recommended to immediately use fertilizers after transplanting into a greenhouse or open ground, since at this moment the bush goes through an acclimatization stage, and the gardener can only overload the plant. One and a half weeks is a sufficient period during which the tomatoes rise and acclimatize.
Any fertilizer should be applied only as needed, and for this it is important to monitor the condition of the foliage and stem. If heavy rainfall occurs after disembarkation, then the amount of top dressing should be doubled, but only if indicated. That is, watering is done more often, but at a lower concentration, so as not to burn the foliage.
There are those who believe that if a simple grass grows well without additional effort, then a tomato will also be able to produce a good harvest. It must be remembered that such vegetables are a selection product, they have the best fruit quality, but they can only provide a crop with additional support. Care and care are the first assistants of the gardener.
The use of active elements increases the biological strength of seedlings, after which it not only quickly grows, but also gives full-fledged inflorescences, strong roots and strong stems that act as highways for delivering the elements necessary for nutrition to the fruits. Nitrogen and potassium are considered the main development assistants, phosphorus is responsible for metabolic processes, which helps to deliver nutrition to all parts of the tomato. A deficiency, as well as an excess of one or another element, will lead to a deterioration in the immune system. This is one of the main reasons why fertilizers should not be applied if the plant does not require them.
Lack of sufficient potassium will result in weak roots that will not be ready to grow in the ground at the time of transplanting. As a result, tomatoes experience stress, take root poorly, wither away. At the first vegetative stage of tomato development, one of the most important roles is played by iron - the first defender of immunity. Determining its lack is easy, just look at the shade of the foliage. If the veins become visible, it's time to feed.
Like humans, the plant needs a certain amount of calcium, the lack of which leads to the rapid growth of a thin and long stem. If you don’t know what exactly can be the cause of the poor condition of the vegetable and admit the possibility of a lack of several elements at once, then carry out a comprehensive diet.
Feeding scheme
It is required not only strictly at a certain time to start feeding, but also not to exceed its amount. At the first stage, the gardener must take care of the quality of the soil and its composition. It is the land with the required nutrients that will become a favorable environment for the development of the plant. The seed will be able to germinate and give the first shoots.
The feeding scheme involves applying fertilizer for the first time, as soon as the first two leaves appear. The second time top dressing is used after picking, not earlier than two weeks later. The third time you can add a nutrient solution two weeks after the second feeding, and then four days before the plant is transplanted into the garden.
Unfortunately, picking is a big stress for tomatoes, but it is vital for seedlings to fully develop further.This is one of the reasons why during this period it is necessary to carry out nutrition, taking into account the characteristics of the nightshade culture, respecting the time and following the schedule.
You can strengthen tomatoes if you feed them ten days before picking.
The secret to growing good tomatoes indoors or outdoors is phosphorus. In order not to burn the roots and stems, fertilizer should only be applied to a moist substrate. First, it is necessary to enrich the earth with phosphorus and nitrogen, therefore it is important to approach the choice of ready-made fertilizer with special attention, having studied its composition in detail. It will not be superfluous to make mineral preparations so that they do not fall on the foliage.
If everything is fine and the plant develops without problems at the second stage, then re-feeding is carried out with the same agent. If you notice that the sprouts have begun to stretch, there is definitely an excess of nitrogen, which is excluded from the composition of the feed. It is useful to increase daylight hours and adjust the temperature in the room, which should not be higher than 18 degrees.
The third stage is characterized by the introduction of foliar organic top dressing. The seedlings will get stronger faster, gain green mass. At the fourth stage, fertilizers are applied by the root and foliar method in the evening, or in the morning. This will prevent UV burns. The emphasis is on the introduction of potassium, which has a fruitful effect on the inflorescences.
Effective remedies
Success with growing tomatoes starts with the soil. Incorporating compost and compost manure at the time of planting, as well as mulching with organic means such as grass clippings or fall leaves, will make a huge difference.
For good growth and for the thickness of the trunk, you can use:
- nitrogen fertilizers;
- organic compounds;
- phosphate fertilizers;
- ash;
- superphosphate;
- urea;
- ammonia;
- ammonia, etc.
Mullein is used for self-growing seedlings in the country, it is brought to the beds in the fall. If you want to feed the bush with it during growth, then it must ferment, otherwise you risk burning the roots. Preparation of the solution does not require additional skills. A mullein in the water must stand in the sun for several days to ferment.
The solution already prepared in this way is added to the water in the required amount and watered under the bush. In the same way, manure is also used, which is preferably applied to the ground in the fall. Before planting, it will proprete and will not harm the root system.
Whether cow or chicken manure is used, the mixture must be rotted if you don't want to ruin the tomatoes.
Of the simplest fertilizers, ash is ideal. It has a huge amount of useful components for a tomato. It can be obtained in several ways:
- from the oven;
- burnt leaves and branches.
Ash contains:
- calcium;
- phosphorus;
- potassium.
They are vital for the rapid development of the plant. Precisely because too many of the elements described above will lead to negative consequences, gardeners recommend making it in the fall and digging up the ground or then adding it to each bed during planting in the ground. If a decision is made to simply cover the area with ash, then its amount per square meter should not exceed 0.5 kg. When making each hole individually, 2 tablespoons are placed inside and no more than that.
No matter how strange it may sound, yeast can also be an excellent top dressing for tomatoes.The result will not be long in coming: the growth of green mass will accelerate, and the harvest will certainly please. The solution is applied to the place where the seedlings will grow constantly. Live yeast is diluted in water in a proportion of ten grams per 10 liters of liquid. To speed up the process, some gardeners add sugar.
Yeast contains a number of substances that are beneficial for healthy plant growth. If you have stale beer, dilute it with water and pour over the tomatoes. Professionals remind that yeast can only be used under the root system.
There are other tricks that will help you get fruits ahead of schedule, for example, the use of iodine. It is enough to pour 4-5 drops into a bucket of water, then pour the tomatoes with the resulting solution. If you spray the foliage, the effect will be noticeable even faster, but the amount of the component should be less - 2-3 drops. Despite the quick positive effect, iodine can damage the plant.
If you decide to use urea as a nitrogen source, then strictly observe the amount of the element and do not recharge more often than the prescribed scheme. It is this component that accumulates nitrates in the fruits, which is why urea is used only when the bushes have already grown and are fully formed. It is allowed to spray or water under the root. To normalize growth, twenty grams per square meter of soil is enough.
There is nitrogen in sufficient quantities and in the composition of ammonia. At the picking stage, ammonia is introduced into the ground. For 8 liters of water, it is enough to add 20 grams of powder. Moreover, ammonia drives away the bear, which, after landing in the ground, can eat up the roots of tomatoes until they are strengthened and fully formed.
For prevention, the concentration is increased to 10 ml per ten liters of water. 0.5 liters of the prepared solution is added to each pre-prepared hollow.
Often, gardeners talk about potassium permanganate, which is sprayed with tomatoes so that they do not lose flowers. It should be used no more than once a month.
Hydrogen peroxide contributes to:
- disinfection of damage;
- prevention of rotting of the root system;
- oxygen saturation;
- boosting the immune system.
An even simpler and more effective way to prepare a recharge is to insist on a banana peel. One fruit per liter of water, infusion time - two days. You can replace the banana with an eggshell, as soon as an unpleasant odor appears - the solution is ready for use.
Sleeping coffee can also be used as fertilizer for plants. Nettle is one of the best balanced fertilizers. To prepare a watering solution, leave nettle leaves in a bucket of water for 3 days. It can be dry or freshly cut. Another option is to grind the dried nettle and add it to the soil.
Some gardeners use milk as a supplement. It contains:
- potassium;
- calcium;
- copper;
- magnesium;
- phosphorus;
- zinc.
Green tea is especially beneficial for plants as they require a lot of iron. Instead of throwing away green tea leaves, simply sprinkle them on the soil under the bushes.
Fishmeal is another natural fertilizer for tomatoes that gives them an extra boost both when transplanting and during the growing season. It is rich in phosphorus, nitrogen and potassium, as well as other important minerals such as magnesium, calcium and sulfur.Available as a concentrated liquid fertilizer, it is made by mixing different parts of fish, including bones.
Unlike composts, nutrients in this version are available to plants immediately.
Alfalfa is a mandatory means of additional feeding with the necessary set of trace elements and beneficial hormones. Tomatoes planted in such compost give a rich harvest.
If you live near the beach, try feeding your tomato plants with algae, which have over 60 micronutrients that are critical to fruit formation. Today on the market you can find such a fertilizer in liquid form.
Not all gardeners are ready to spend time preparing mixtures and solutions, it is much easier to purchase a ready-made product, which is sufficient, in accordance with the manufacturer's recommendations, to be diluted in water or sprinkled on the ground. Among them:
- "Ideal";
- "Fortress";
- nitroammophoska;
- superphosphate;
- "Epin".
The main thing that is required from the gardener is to strictly follow the instructions. Use at higher dosages will result in nitrate buildup in tomatoes.
Mineral fertilizers have been used for quite a long time, they help to accelerate the growth of seedlings, strengthen the root system. Superphosphate is used more often than others, and all because it is rich in a large number of trace elements. Potassium sulfate does not contain chlorine, it helps to strengthen the immune system and increase the number of fruits on the bushes. If you want to accelerate the growth of foliage or shoots, then use ammonium nitrate.
You should not add only one specific element to the soil or to the plant; complex top dressing is the most effective way to help tomatoes.
If you decide to prepare the solution yourself, then take in the following proportion for two liters of water:
- 1 g of urea;
- 3 g potassium sulfate;
- 8 g of superphosphate.
The solution is used for root irrigation.
For foliar and root use can be dissolved in 1 liter of water:
- 0.6 g of ammonium nitrate;
- 4 g superphosphate;
- 1.5 g potassium sulfate.
For the thickness of the stem, many gardeners use organic fertilizers. They are distinguished by a large amount of nitrogen in the composition, so it is advisable to use them in the early stages of development. The recipe is simple: 1 kilogram of bird droppings is diluted with 10 liters of water and insisted for several days.
Not all gardeners are ready to use chemicals when growing crops: in terms of quality and positive effect, folk remedies are in no way inferior to them, but are considered safer.
You can use magnesium sulfate, which is added to each well in a tablespoon or used as a spray solution. Two tablespoons are enough for a liter of water. Benefits of using:
- small price;
- simplicity;
- fast effect.
How to apply fertilizer correctly?
It is just as easy to fertilize the seedlings on the windowsill as after planting it in the ground. Foliar top dressing is considered preferable, care is easier and watering can be done by accurately calculating the portion. The foliar method is good precisely on open ground, since the plant is pollinated with fertilizer, it is not easy to do this at home, so as not to apply it to surrounding objects.
Urea is excellent for the first two stages of development, which must be diluted strictly in a certain proportion, otherwise you can burn the roots. The lack of moisture on the foliage at first prevents the appearance of fungus and other diseases.Tomatoes have a special relationship with high humidity, so gardeners are advised to ensure that its level does not exceed the permissible level.
Before the solution is applied to the ground, the ground should be moistened, but not too much. At the stages when foliage and inflorescences are formed, fertilizer can be sprayed. So the effect can be achieved faster, because through the pores in the leaves, the elements enter the life support system in less time. Spraying is carried out in the morning so that the sun's rays through the drops do not burn the bush.
Fertilizing through the soil takes a long time until the roots deliver nutrients to all parts. The green mass absorbs trace elements almost immediately, such emergency assistance is necessary when it is urgent to save the crop. But it is worth remembering that when creating a spray solution, the number of elements in it must be reduced.
Not a single plant can do without boron, since it is he who is responsible for the taste of fruits. Tomatoes become sweeter, more ovaries appear, and, accordingly, the amount of the crop increases markedly. It is he who helps protect tomatoes from certain diseases and parasites. The preparation of the mixture requires compliance with the recipe.
1 gram of boron is added to one liter of heated water. The liquid is allowed to cool, and then sprayed onto the foliage and ovaries, covering, among other things, the already formed fruits. One bush takes at least 10 ml of the composition.
Organic compounds are not forbidden to be applied under the root, but in a diluted form so as not to damage the roots. If the earth is too acidic and the plant with its whole appearance signals a lack of phosphorus or calcium, then it is recommended to use foliar top dressing.
It should be understood that acidic soils with low pH and high clay content are deficient in macronutrients: N, P, K, Ca, Mg and S, while alkaline soils contain insufficient amounts of B, Cu, Fe, Cl, Mn, Mo and Zn. Soil with a pH between 6.0 and 6.5 contains adequate amounts of both sets of nutrients.
Not every gardener knows how to determine what kind of top dressing to carry out. As mentioned above, nutrient deficiencies in plants have their own symptoms.
Nitrogen deficiency:
- small or light green leaves;
- very slow growth and short stems;
- flower buds fall off.
Corrected by adding a mixture with a high nitrogen content, such as blood meal.
Phosphorus deficiency:
- foliage color purple;
- small leaves;
- late fruiting.
You can correct the situation by adding bone meal to the soil.
Potassium deficiency:
- slow growth;
- fruit ripening uneven;
- dying leaves.
The problem is fixed by adding a potassium-rich fertilizer such as potash or mulching with organic material.
Boron deficiency:
- black areas at the growing point of the stem;
- stems with stunted growth;
- abnormally fluffy plant.
It is best to feed with manure.
calcium deficiency:
- upper leaves turn yellow;
- plants seem weak;
- thick, woody stems with dead zones.
The situation can be corrected using bone meal.
Magnesium deficiency:
- fragile, twisted leaves;
- fruit without taste.
To help the plant, fertilizer is made by mixing dolomite lime and one tablespoon of salt.
Which tomato fertilizer you use will depend on the current nutrient content of the available soil.Before you start adding elements to the soil to support tomatoes, it is best to find out what is missing.
If the soil is properly balanced or high in nitrogen, it is necessary to use fertilizers that have lower nitrogen and phosphorus levels, such as 5-10-5 or 5-10-10. Such compositions are mixed, they are easy to use. If there is not enough nitrogen, use a mixture such as 8-8-8 or 10-10-10. If you can't test the soil, but have never had problems growing tomatoes in the past, you can assume the soil is balanced and use a fertilizer with a high phosphorus content.
Fertilization should begin after the flowers are fertilized. Then, according to a strict scheme with the same interval, additional top dressing is applied until the first frost. If you want to help the plant in the first stages of planting, then add a little mixture to the hole where you put the tomato. In such soil, it will quickly take root and grow.
In most cases, the fertigation method is used to apply fertilizers, that is, it is necessary to dissolve them in water and then pour the solution under the root of the plant. At the same time, properties such as the solubility and compatibility of certain elements must be taken into account. The frequency of fertilization at each stage of growing a tomato depends on the properties of the soil/substrate and its ability to retain moisture. The tomato must receive an adequate supply of all the necessary nutrients so that the gardener can reap a decent harvest.
As a chemical fertilizer, a product is made that contains one or more essential nutrients in an available or potentially available form. Such products are less bulky, easy to transport and readily available to plants.They are sold in granular, powder or liquid form.
Among the main advantages:
- contains a balance of essential nutrients;
- does not contain salts that harm the natural biology of the soil and kill good bacteria;
- contains a special form of ammonia that promotes flowering;
- a unique blend of minerals that enhance the flavor of the fruit;
- contains humic acid to stimulate growth;
- improves the physical properties of the soil.
In addition to formulations that have only one chemical compound, there are mixed formulations containing two or more compounds in suitable proportions. Recommended dose of chemical fertilizers for tomato:
- nitrogen - 66-110 kg/ha;
- urea or ammonium sulfate - 35-60 kg / ha.
During fertilization, nitrogen, phosphorus and potash should be laid in the soil before planting, the rest of the nitrogen should be applied in 2 equal doses after 30 and 60 days.
Urea spray is useful when plant growth is slow, a component (2-3%) is sprayed depending on the age of the plant, boron and calcium are also applied as a foliar spray. Fertigation soluble fertilizers are mixed together with water and applied by drip. The amount of the three essential plant nutrients (N, P and K) required for soil application can be determined using a soil test.
When fertilizing tomatoes at planting time, mix the fertilizer into the soil at the bottom of the planting hole, then add some more regular soil on top of this before placing the seedlings in the ground. If the top dressing comes into contact with the roots, it can burn them.
After watering, the fertilizer is spread on the ground, starting at about 10 centimeters from the base.Too close a location can lead to the fact that when watering or during rain, top dressing will fall on the stem and burn it.
Proper feeding takes into account a number of rules:
- the composition should not be cold or hot, it is worth considering the temperature;
- when buying a new product, use it only on one plant;
- no excess organic matter;
- top dressing is carried out in the evening;
- root feeding is not carried out on dry soil; previously, the ground under the bushes is watered;
- the concentration of liquid fertilizers should be such as not to damage the foliage.
If you are using a water soluble fertilizer, try to avoid spraying the plants themselves. Instead, focus your efforts on the roots. The tomato gets almost all its nutrients through the root system.
Tips from experienced gardeners
Experienced summer residents share advice, which help even a beginner to grow a decent crop in his garden.
- It is very useful to keep a diary where you should make notes when the fertilizer was last applied. After planting in the ground, you can repeat the process every two weeks, and with the normal development of plants, abandon it.
- If you used a pre-enriched soil mix, then you do not need to fertilize the seedlings, but if some of the leaves turn yellow, use liquid solutions with nitrogen or phosphorus of a lower concentration. After a few days, under high-quality light, the young tomato will quickly grow. Some experienced gardeners transplant the vegetable into large containers during this period to make it strong.
- Feed the crop with liquid balanced fertilizers such as compost, comfrey tea or solid organic fertilizers in powder or granular form.Liquid fertilizers can be watered around the base of the plants or applied directly to the leaves of the crop. Solid fertilizers are scattered or laid out around the root system of each plant.
- Gardeners get a big harvest and large tomatoes using a variety of fertilizers. There are several reasons why they prefer to use only organic mixtures - they provide the plant with the necessary trace elements for a long time and do not harm them, keeping the fruits safe. In turn, chemical inorganic fertilizers have some advantages. They are generally cheaper and take less effort to prepare.
- Organic fertilizers derived from plants and animal products are great for the long term. They can be used from autumn, thus preparing the soil for future planting. Such top dressing does not harm the root system.
Other benefits:
- improving the condition of the soil;
- help in the absorption of nutrients.
The most commonly used organic fertilizers are:
- fish emulsion;
- blood meal;
- bone flour;
- compost and compost tea;
- manure.
- Today, ready-made inorganic fertilizers are widely used, made in the form of mixtures: ammonium sulfate, mineral soil. They are rated by percentages of nitrogen (N), phosphorus (P), and potassium (K). All fertilizers have a high percentage of phosphorus, their proportion looks like 5-10-5, where 5 is nitrogen, 10 is phosphorus and 5 is potassium.
- Some gardeners use both organic and inorganic substances at various stages of plant growth.It is recommended to use inorganic 5-10-5 mixtures in a weak water solution to feed the seedlings once a week, along with organic mulch and compost to enrich the tomatoes.
- An alternative, easy way to feed tomatoes is with a controlled release fertilizer that works for a long period of time.
- It is not always necessary to apply additional fertilizers to the ground. This happens if a ready-made and saturated with minerals and organic soil is purchased for seedlings.
Summing up all of the above, we can conclude that the use of additional top dressing helps the plant to better adapt to transplanting into the ground, and the gardener to harvest a decent harvest. An excess, as well as a lack of calcium, bromine, phosphorus, nitrogen and other elements, leads to disruption of the normal growth and development of the plant.
Before applying fertilizer, it is advisable to do a soil test, which will help determine the lack of one or another element in the soil. If this is not possible, the gardener should take a closer look at the plant and determine the nutritional deficiency by the first signs.
