Nowadays there are many different types of fertilizers. Some people prefer to use mineral fertilizers, while others trust only organic matter that has been proven over the years.

In our article today we will talk about feeding tomatoes with yeast. You will learn popular recipes for preparing compounds, rules for applying fertilizers and available contraindications.

How to use yeast for tomatoes

Yeast
The use of the most common yeast as a fertilizer began in Soviet times, when there was not such a variety of fertilizers on the market. The use of yeast provides the plant with a sufficient amount of useful and micronutrients and has a beneficial effect on the immune system.

Beneficial features

Yeast-based fertilizer has a beneficial effect on plants of any age. Its effect is most noticeable on young seedlings. Yeast:

accelerate growth;
increase immunity;
promote lush flowering;
increase productivity.

Also, such fertilizer allows seedlings to quickly take root in a new place after picking and planting in open ground or a greenhouse.

INTERESTING. In terms of its effect on young seedlings, yeast can be compared with complex mineral fertilizers.

In addition to plants, yeast fertilizer has a beneficial effect on the soil. Microorganisms in the soil are stimulated, the processes of mineralization and the formation of beneficial carbon dioxide are enhanced.

BY THE WAY. Another important advantage of yeast fertilizer is its low cost.

Flaws

The main disadvantage of such solutions is that their beneficial effect appears only in warm weather. That is, fertilizers can be applied from late spring to late summer.

In addition, yeast feeding is completely useless during cold weather. It just won't start working.

Yeast should not be used as a fertilizer more than 3 times, since during the fermentation process it absorbs a lot of potassium from the soil. Therefore, frequent use of yeast nutrition can lead to a deficiency of this element.

When and how to feed seedlings and adult tomatoes?

Fertilizing tomatoes with yeast solutions prepared at home can be carried out at all stages of plant growth - from watering seedlings, after picking, to fertilizing during active fruit ripening. It is especially effective to apply fertilizing to warm, well-heated soil in a greenhouse several days before planting young plants in it. The earth will have time to become saturated with phosphorus, the fungi will begin to actively process and improve the structure of the soil in which it is planned to plant the seedlings.

Yeast as fertilizer for tomatoes

Yeast fertilizer concentrate
The greatest effect from yeast-based fertilizers is achieved when used in combination in the form of root and foliar feeding. The result of use is usually noticeable after a few days. Especially on young seedlings. The tomatoes are growing and looking noticeably stronger.

When feeding adult plants, the formation of ovaries accelerates, the fruits fill and ripen faster.

This effect is achieved for the following reasons:

yeast contains many trace elements, proteins, vitamins and amino acids;
Yeasts are essentially fungi that contribute to the processing of organic matter and the formation of substances beneficial to plants.

REFERENCE. To enhance the effect, experienced gardeners advise pre-fertilizing with organic fertilizers. In this case, 10-14 days should pass between the addition of organic matter and the addition of yeast.

What other plants can be fed with yeast besides tomatoes?

After you have mastered the recipe for yeast nutrition for tomatoes, and your favorite composition has already appeared, you want to use it somewhere else. Tomatoes respond best to such fertilizer; it is also wise to use it on peppers and cucumbers. Yeast feeding for cucumbers and tomatoes is a very environmentally correct solution.

But you shouldn’t limit yourself to them. All plants in the garden and vegetable garden, as well as in the room on the windowsill, will be happy with this nutrition. You can use any of the following recipes for yeast plant nutrition.

How to breed yeast to feed tomatoes: recipes.

In practice, yeast nutrition for tomatoes is prepared quite simply. For this purpose, baked goods are equally suitable, either fresh or dry or in granules.

Recipes for preparing fertilizer for tomatoes are:

Dry yeast (5 g) along with sugar (1 tbsp) is dissolved in warm water (5 l) and left for 2-3 hours to infuse, and right before use, diluted at a rate of 1 to 5.
Fresh yeast (1 kg) is placed in a container with heated water (5 l). Immediately before use, this composition is re-diluted in a ratio of 1 to 10.
You can also use alcoholic yeast, which, when combined with sugar, forms a “mash.” With its help, you can fertilize tomatoes quite effectively. To prepare it, you need to take yeast (100 g), granulated sugar (100 g), mix everything well and dilute it in warm liquid (3 l). The container in which the mixture is mixed is covered with gauze and left in a warm room for a week to let it brew. Before watering, take 1 glass of this liquid and dissolve it in a bucket of warm water, and then pour it over the tomatoes at the rate of 1 liter for each root.

Yeast feeding is designed not only to make tomatoes stronger, but, at the same time, to help them withstand the summer heat more easily. To do this, make a solution: take 100 g of fresh yeast in a bucket of warm water. 1 liter of the resulting liquid is poured under each tomato once a week.

Next, we recommend watching a video that shows how to properly prepare yeast fertilizer for tomatoes:

How and at what time is it better to feed tomatoes.

Tomatoes of any variety are treated with yeast, no matter where they are grown: in open ground, in beds, or in greenhouses. When using such fertilizing, it is important to take into account that the soil must be sufficiently warmed up, since they “work” only in a warm environment, and there is no point in introducing them into cold soil.

Seedling.

Tomato seedlings are fed after they have been planted. This allows it to quickly take root and take root. The solution only requires yeast and water. It is poured into a small watering can and the plants are watered at the roots.

You can also use foliar feeding. To do this, the yeast solution must be filtered, poured into a container with a sprayer and sprayed on the tomatoes, working in turn first on the stems, the inner, and then the outer parts of the leaf blades.

For young seedlings, such spraying has a greater effect, since the liquid is quickly absorbed by the leaves and immediately penetrates deep into the cells. You should not be careful about burns, since unfermented pure yeast simply does not have such properties.

Mature plants.

Tomatoes that were planted in open ground in beds in a permanent place need to be fed 1.5-2 weeks from the day they were planted. After another 2-3 weeks, watering is repeated, and before flowering - another one. For each bush take 1-2 liters of solution, but the dose should not be increased.

In greenhouse conditions, tomatoes are fed according to the same scheme as those growing in open ground.

Basic recommendations for gardeners.

Gardeners planning to fertilize tomatoes with yeast need to remember certain rules of conduct with this fertilizer, for example:

It is advisable to watering either early in the morning or in the evening.
It is important to observe the required dosages and not to water frequently.
The soil under tomatoes during root watering should be neither wet nor dry, but moderately moist.
A solution made from sugar is more effective when poured under the roots of plants, rather than on their leaves.
You should only use a freshly prepared solution at room temperature, since if it sits too long, it will lose its beneficial properties.
You cannot add yeast at the same time as bird droppings and manure, since the activity of fungi will be significantly reduced. At the same time, it is allowed to use powder from eggshells, ash, hops, green weeds, and tops of garden crops.
Since yeast absorbs calcium in large quantities during its functioning, ash is added to the tomatoes along with it.

Properly carried out yeast feeding of tomatoes will contribute to the good growth and proper development of tomatoes, and will also have a beneficial effect on their yield and fruit quality.

Reviews from experienced vegetable growers.

Based on reviews from gardeners who used yeast fertilizer in their tomato beds, we can draw some conclusions regarding the use of such fertilizer on their plot of land.

Maxim: I use this fertilizer every season. Its preparation is simple and does not require extra effort and time, and the end result is excellent. I water seedlings and bushes planted in the soil with it. Within a few days I notice an improvement in the appearance of the tomatoes: they become stronger, greener and richer. I think that such “live” feeding should not be ignored at all.
Nikolay: I grow tomatoes only on an organic basis. Yeast feeding is included in the complex of my care for this garden crop. During the season, 3-4 waterings are enough for me to accelerate the growth of plants and in the end get an increase in yield. I advise anyone who wants to grow organic tomatoes to use this type of feeding.
Pavel: I heard about this feeding from many fellow vegetable growers. According to them, tomatoes always respond positively to its use: their appearance and overall well-being improve. Based on their recommendations, I decided to water my tomato plantings with this yeast solution and I was pleased with the result.

How to prepare a solution for feeding

Preparing fertilizer is not too difficult. But you need to adhere to a few basic rules.

Yeast must be mixed with warm water to activate its action.
Fertilizer concentrate must be infused in a warm place so that it begins to ferment.
The prepared solution most often needs to be filtered before use. Especially in the form of foliar feeding.
Yeast fertilizer only works in warm weather.
Top dressing is not stored for long and loses its beneficial properties over time.
Yeast feeding works best together with other ingredients (ash, chicken manure, sugar, etc.).
Fertilizers are best applied to moist soil.

Feeding rules

Simple rules allow yeast to operate effectively in the soil.

Treatment is carried out on warm days, when the soil has warmed up sufficiently.
Fertilizer is applied to moist soil. If there has been drought for a long time, you need to moisten the soil before the procedure.
In one season, three yeast feedings are enough.
The remaining solution can be used to treat the stems and leaves of plants against late blight.

Some secrets of use

Recently, there has been a stir among summer residents around black yeast. It is believed that they are more suitable for fertilizing the soil. The product increases the survival rate of seedlings and increases plant endurance.

Important ! Yeast cannot be considered a panacea for all diseases. In addition, they are unlikely to be able to significantly increase the yield on poorly fertile soil.

Yeast works effectively only in heated soil. The first fertilizing can be carried out as soon as the soil temperature rises to +15C. In greenhouses this period usually occurs a month earlier.

In polycarbonate greenhouses, plant growth occurs faster due to more favorable temperatures. For the first two feedings, you can use a yeast solution without infusion.

Yeast fungus is not afraid of frost, heat and temperature fluctuations . However, other active microorganisms can inhibit its action, so experienced summer residents do not use yeast in combination with bird droppings, manure and chopped grass. It is better to apply all these natural fertilizers before planting seedlings.

Important ! If the root solution gets on the leaves of the plant, you need to wash it off with water, otherwise it will burn.

Before fertilizing with yeast, you need to water the soil generously with water heated in the sun, and also loosen it so that the beneficial substances can penetrate deeper.

Foliar yeast feeding

Foliar treatment is intended to protect the plant from diseases and pests . Yeast solution is also suitable for this procedure. Observations have shown that the active compounds in the product protect against late blight.

To spray tomatoes you will need: 100 g of yeast, 1 liter of warm milk, 30 drops of iodine. Milk and yeast are mixed and then left in a warm place for several hours. The concentrate is diluted with water so that the total volume is 10 liters, then iodine is added.

The bushes are thoroughly sprayed with a solution to prevent late blight. Treatment is carried out twice a season: before flowering and fruiting.

Dosage and stages of fertilizing in open ground

Feeding tomatoes with yeast
You need to water tomatoes with yeast fertilizer at the rate of 1 liter per plant. For large bushes you can increase the volume to 2 liters. It is very important to maintain proportions when preparing the solution.

There should be 3 yeast dressings in total.

First stage

10-15 days after planting tomatoes in the ground. At this time, we help the tomatoes take root better in their new location and stimulate the growth of stems and leaf development.

Second phase

15-20 days after the first feeding. The tomatoes have already grown, and we stimulate flowering and fruit set with yeast feeding.

Third stage

When the first ovaries appear on plants. The purpose of this feeding is to give the tomatoes additional energy for fruit formation. In addition, yeast has a positive effect on the taste of tomatoes.

How to make fertilizer from yeast

Fertilizing plants with yeast began to be actively used in the 70s of the last century. With the advent of chemical and other additives, interest in this method of feeding has fallen. But with all the advantages of various biocomplexes, yeast remains a useful fertilizer. They are responsible for plant growth by activating resources that other additives do not use.

How to prepare yeast fertilizer for tomatoes

There are a large number of ways to prepare yeast solution for tomatoes. It all depends on capabilities and personal experience. There is plenty to choose from: yeast with sugar, fermented yeast, with herbs and chicken droppings. But traditionally, without various additives, the solution is prepared based on the following proportion: for 1 kg of yeast (preferably baker's yeast) - 5 liters of water. Yeast in briquettes is suitable for this, which will be more economical than in granules. The water must be warm so that the microorganisms in the yeast “wake up”. By the way, the soil also needs to be heated before watering. The resulting solution should be left for a day, and then 0.5 liters should be diluted in 10 liters of warm water. Total: 10 buckets with the necessary solution. This amount is enough for 20 bushes, with this calculation: use half a liter for 1 bush for young tomatoes and two liters for an adult. When watering, the soil should be slightly moist, but not wet or dry. It is advisable to carry out the procedure no more than twice a year, first a week after transplanting into the ground, and then before flowering begins, preferably in June.

How to do foliar feeding?

Foliar feeding involves spraying tomato leaves. Typically, this method is used when urgent application of fertilizers is required. The solution is quickly absorbed by the leaves and acts immediately.

Foliar feeding with yeast

Foliar feeding is carried out according to the following rules:

The concentrate must be further diluted twice more in the same proportions.
Spraying should not be carried out in sunny and hot weather.
In greenhouses and greenhouses, spraying is carried out in the morning.

Conclusion about the benefits of yeast fertilizers during the ripening of tomatoes and other vegetables

Thus, by adding a solution of yeast and readily available potassium to the tomatoes at a time when the bushes are simultaneously forming ovaries on the upper clusters and filling the lower tiers with fruit, you will help increase the yield and improve the marketability of the harvested tomatoes. The same statement is true for pumpkin crops growing in open plantations and greenhouse beds - cucumbers, zucchini, pumpkins, squash, as well as eggplants and sweet peppers, which, like tomatoes, belong to the nightshade family.

Easy work and good weather for you this season!

Features of feeding seedlings

Tomato seedlings are fed with a yeast solution after picking. Fertilizer will allow plants to better tolerate the transplantation process and take root in a new place. In addition, in this way we stimulate root formation.

No other elements are usually added to yeast fertilizer for seedlings. Watering is done at the root.

When foliar feeding, the solution is filtered and further diluted with water.

IMPORTANT! To feed seedlings, yeast does not need to be allowed to ferment. That is, you simply mix them with water and immediately treat the tomato seedlings.

When should you apply fertilizer?

When planning to use yeast nutrition, you need to consider the following factors:

Season. It is allowed to fertilize plants at the root only when the earth is warm. There is no need to rush the first time; it is recommended to wait until the end of spring or the beginning of summer. During this period, the earth is warmed up, useful elements are completely absorbed. Another important factor is the time of use of fertilizing. It is best to fertilize tomatoes at dawn or dusk, when the sun is not shining too much. If tomatoes grow in a greenhouse, fertilizing should be done in the morning so that the tomatoes dry out before sunset.
Soil condition. If the open soil is dry, it needs to be slightly moistened before applying fertilizer.
Dosage. Do not think that yeast fertilizers are generally harmless. An overdose can cause the condition of tomatoes to deteriorate and the yield to decrease.
Frequency of application. Tomatoes are fertilized with yeast a maximum of three times per season. The product fills the soil with nitrogen elements, but removes potassium and calcium. In view of this, it is advisable to add wood ash to the fertilizer or sprinkle the ash on the beds.

How to feed tomatoes with yeast in a greenhouse

Fertilizer application for tomatoes growing in a greenhouse follows the same pattern as in open ground.

The first feeding is carried out 10-15 days after planting the seedlings. The second - after another 15-20 days. The last feeding is carried out when the first ovaries appear on the plants.

IMPORTANT! Foliar feeding of tomatoes in a greenhouse is best done in the morning. This is necessary so that the tomato leaves have time to dry during the day. At night the temperature drops, and moisture on the leaves can provoke a fungal disease.

How to treat tomatoes with boric acid

Another important element that tomatoes need for successful fruiting and development is boron. Boric acid allows you to nourish the plant, activate its flowering, prevent the shedding of ovaries, the development of diseases and the invasion of parasitic insects. All this can be achieved if spraying is done correctly.

Find out also how to get rid of midges on tomatoes.

No special skills are required to feed plants with boric acid. You just need to properly prepare the solution and spray it with a spray bottle. The consumption of working fluid is 1 liter per 1 sq. m or 10–15 ml per 1 bush. The solution is prepared in different ways, depending on the purpose for which it is used.

Seedlings

In order for seedlings to grow quickly and develop properly, it is necessary to soak the seeds in boric acid before sowing. The solution is prepared by mixing 0.5 g of powder with a liter of warm water and infusing for 24 hours. The seeds are placed in gauze and then placed in a container with boron liquid. Soaking duration is 24 hours.

Mature plants

Spraying of adult plants is carried out twice per season - during the blooming of flowers and during the ripening of fruits. The break between them should be at least 10 days.

We recommend reading how and why to treat tomatoes with iodine serum.

During flowering

For foliar feeding during flowering, prepare a mixture of 10 g of powder and 10 liters of hot water. The crystals should completely dissolve. Then the solution is collected in a spray bottle and sprayed onto the leaves and stems.

Before spraying the entire area, you need to treat one plant. If after 24 hours no negative changes have occurred, you can begin feeding the remaining tomato bushes.

Root treatment is also an option, but in this case it can cause a burn to the rhizome. To prevent this from happening, the plant should be watered abundantly before feeding.

Fertilizers are applied by any method on a cloudy day in the absence of precipitation. During the dry period, the concentration of the working solution is reduced by 0.5 times. Spraying is carried out in the evening.

Important! If after the first treatment the condition of the tomato bushes has worsened, the second spraying is not carried out.

During fruiting

As soon as the fruits on the bushes begin to turn brown, they can be fed again with boron-containing liquid. Such processing will preserve the presentation of vegetables longer and improve their taste by increasing the sugar content.

The solution is prepared in the same proportion as when feeding during flowering.

Treatments with boron-containing liquid are also carried out when the plant lacks boron. This problem is evidenced by curling, drying out and yellowing leaves, curved tops, the formation of brown and light spots on the foliage, and shedding of flowers and ovaries.

Fertilizers containing yeast

Fertilizers containing yeast
The effectiveness of yeast fertilizers has not gone unnoticed by the agrochemical industry.

EM preparations work on the same principle as yeast . These are special compositions with microorganisms, the action of which is aimed at improving nitrogen fixation, preventing plant diseases, increasing the productivity and taste of fruits.

The most popular fertilizer in this group is Baikal EM . Now it can be purchased at any hardware store. Therefore, if you do not want to prepare yeast fertilizer yourself, but want to get the effect of its use, you can use this drug or its analogues. Other EM concentrates include “Vostok EM”, “Gumat EM”, “Emiks”, “Emochka”, etc.

Methods for pitching yeast in a greenhouse

Now you know all the popular recipes for preparing yeast fertilizers. In addition, I will tell you what is better to use for root watering and what for foliar spraying.

Root feeding

The first root watering is indicated for tomatoes at the seedling stage. For young plants I dilute the following solution:

For 1 liter of water – 100 g of fresh yeast.
I insist for a couple of hours.
I dilute the mixture with regular water to 10 liters.

I use the composition on the same day. As soon as the first signs of fermentation appear in it, it is better not to use it for seedlings - such a mass is only suitable for adult plantings. Yeast feeding will help young seedlings form strong stems and develop evenly without stretching.

The second root feeding is after moving to the greenhouse. Use the same recipe for seedlings, or you can prepare the following compositions:

Traditional yeast. For 1 kg of wet yeast - 5 liters of heated water. I stir the mixture and let it sit for 1-2 days. After the characteristic smell of sourdough appears, I dilute the liquid with warm, settled water 1:10. Depending on the size, I pour 0.5-1 liters of fertilizer under each bush.
Yeast with sugar. For 3 liters of warm water – 100 g sugar, 100 gram yeast briquette. I stir, cover with a lid, and take it to a warm place to infuse until fermentation begins. For root watering, I dilute 200 ml of concentrate in 10 liters of water. One bush requires up to 1 liter of composition.
From dry yeast. For 10 liters of warm water – 10 g of powdered yeast, 2 tbsp. spoons of sugar. The older the tomatoes, the longer I insist on fertilizing - from several hours to several days. Don’t forget to dilute the concentrate with water 1:5 before watering.

At the same time, following the general rules of root fertilization:

Before fertilizing, I water the plants thoroughly with warm water and loosen the damp soil.
To feed tomatoes I use liquid fertilizer at room temperature.
I plan the procedure for the evening hours, after sunset.

I carry out root feeding without any special frills - I try to carefully pour the liquid under the stem, without splashing it on the tops.

Foliar feeding

If the main purpose of root watering is fertilizer, then the task of foliar watering is natural protection from pests and infections. Yeast treatment is an effective prevention of late blight. For these purposes I prepare the following composition:

For 1 liter of warm milk (replaced with whey) - 100 g of wet yeast.
I insist for several hours.
I add regular water to a total volume of 10 liters.
I add 30 drops of iodine to the working composition and stir.
I pour the liquid into the sprayer and carefully process the tomato bushes from bottom to top.

I plan the treatment on a cloudy day or evening hours to avoid burning the leaves. For greenhouse tomatoes, two such feedings per summer are enough - before flowering and before fruiting.

Foliar feeding is more indicated for young plants at the seedling stage. Their important advantages:

Through capillaries, nutrients quickly enter the “body” of the plant.
Yeast feeding strengthens the seedlings - the stem becomes powerful and lush green foliage appears.
When applied foliarly, useful components are absorbed in a larger volume, since they are not washed out into the layers of the soil mixture, where the roots can no longer reach them.
More economical use of fertilizer.

For foliar application, use all the recipes I listed above, but with an important condition: I reduce the concentration by 2-3 times. I carry out the treatment using a regular sprayer, slowly - it is important to moisten both the stem and the foliage on both sides.

The best time to fertilize is a cloudy day or evening. Drops of liquid in the sun cause burns. Moreover, the fertilizer dries quickly before it has time to be absorbed. If the plant is already planted in the greenhouse, plan the procedure for early morning.

Contraindications for using yeast

Despite the fact that yeast is a practically safe fertilizer, it still needs to be used carefully.

Firstly , due to yeast, there is less potassium in the soil. Therefore, if your tomatoes lack potassium, then fertilizing should be postponed.

Secondly , for foliar feeding, yeast fertilizer is diluted in an even weaker concentration. This is necessary in order not to “burn” the tomato leaves.

Thirdly , yeast fertilizers are used only in warm weather. Otherwise, fermentation processes will not be activated.

Fourthly , you should not feed yeast to tomatoes suffering from fungal diseases. It will be much more useful to treat such plants with fungicides.

Pros and cons of such feeding

Recently, feeding tomatoes with yeast has become increasingly popular. The positive impact of their presence is as follows:

After fertilizing is applied to the soil, the process of fermentation and processing of organic matter contained in the soil, which begins under the influence of yeast, leads to the formation of a number of amino acids, carbohydrates, vitamins, proteins and easily digestible mineral components (organic iron, etc.) that are very useful for plants.
Being a single-celled fungus, yeast successfully suppresses the development of another pathogenic fungus that is extremely dangerous for tomatoes - late blight.

The accumulated experience of using yeast as part of fertilizers has made it possible to establish their good effectiveness in terms of:

significant stimulation of the formation and development of the root system;
strengthening seedlings and increasing their resistance to transplantation;
general growth and resistance of plants, increasing their productivity;
improving soil structure and fertility.

Such positive results were noted not only when feeding tomatoes and cucumbers with yeast, but also when growing other crops, in particular beans, root vegetables, zucchini, various melons, fruit trees and berry bushes.

Strawberries (strawberries) “respond” especially well to this type of feeding, as their rosettes begin to rapidly and efficiently root.

Minuses

Some disadvantage of fertilizing tomatoes with yeast is that its use depletes the soil of calcium, and, what is especially important, potassium. Considering this, as well as the fact that there are no natural sources of potassium entering the soil, it is necessary to provide for the replenishment of this important element in the soil.

Another disadvantage may occur if yeast is used in excess. If the dosage is exceeded, the possibility of disturbing the soil microflora due to too intensive development of yeast bacteria cannot be ruled out. The latter, having processed the organic matter in the soil, can turn the initially fertile soil into impoverished, rocky and difficult to cultivate, although at first the results of cultivation will only be pleasing.

Important!

Based on the above, using this type of feeding (which rather functions not as feeding, but as a growth stimulator) more than three times per season seems risky. Therefore, in order not to devalue the effect of its use, this fertilizing must be alternated with other types of fertilizing, especially in different phases of plant development (during flowering or during fruiting).

Possible mistakes

Too frequent fertilizing. Seeing the results of applying yeast fertilizer, you may be tempted to feed your tomatoes with yeast too often. But you can’t do that. The optimal number of feedings is 3 for the entire season.
Preparation of the solution in cold water. Yeast needs warm water or other liquid to begin fermenting.
Applying fertilizer in cold weather. Everything said above applies to this point. Yeast only works in warm conditions.
Too concentrated solution for foliar feeding. When spraying tomatoes with yeast fertilizer, the concentration must be reduced. To do this, the prepared solution is diluted at least 2 more times.

In what form is it better to apply?

It does not matter what kind of yeast is used for fertilizer - raw or dry. Both will be equally effective. It is possible to make fertilizing even from old bread with crackers.

Raw

Recipe for making fertilizer from dry yeast:

Place 100 grams in a ten-liter container filled with heated water.
Pour 2 tablespoons of sugar into the container to activate fermentation.
Wait 2 hours.
Dilute the resulting mixture in 50 liters of water.

Dry

Recipe for preparing fertilizer from raw product:

Mix 200 grams of raw yeast with one liter of milk.
Wait a couple of hours for the starter to increase in volume.
Dilute the finished mixture with water (the volume of water should be ten times the volume of the mixture).

FAQ

Preparation of yeast fertilizer concentrate

Why do you need to feed plants with yeast?

Yeast is a source of many vitamins and minerals, as well as a growth stimulant. Using them as fertilizer improves plant health and stimulates growth. Yeast is also good for the soil.

How to properly prepare fertilizer from yeast?

Yeast is diluted in warm water and left to ferment. This produces a concentrate, which is then diluted with water and the tomatoes are treated with the resulting composition.

What to do if the plant gets worse after feeding it with yeast?

Feed the tomatoes with potassium and calcium compounds and next time reduce the concentration of the yeast supplement.

How long can yeast nutrition be stored?

Fertilizer should be applied immediately after preparation. Every day it will lose its beneficial properties. If you don’t have a lot of tomatoes, then adjust your feeding schedule in such a way as to treat not only tomatoes, but also other vegetables.

Why didn’t fertilizing give any results?

Firstly, you may simply not see the external result. This happens especially often when processing mature plants. Secondly, you need to apply yeast fertilizer only in warm weather. When it's cold outside, this feeding will not work.

What is yeast feeding

First, you need to decide what baker's or baker's yeast is, and it is about them that we will talk, how they live, what they eat, and how they can be a plant food. Yeasts are single-celled fungi from the Saccharomyces family that do not have mycelium and live in liquid and semi-liquid substrates rich in organic matter.

Please note that yeast lives in liquid and semi-liquid substrates, which soil is not. Moreover, they are quite demanding in terms of nutrition, consuming fats, carbohydrates and organic acids. But compounds found in the soil such as cellulose or lignin, which are the remains of plant stems, are inaccessible to them.

All this suggests that the soil is far from their habitat and they will not be able to live there for a long time. They will live longer in moist and organically rich soil, and will die immediately in dry and poor soil. So why are they so praised and what is the use of them?

I hope I won’t make a discovery for anyone if I say that yeast doesn’t eat tomatoes. They eat only the waste products of yeast, which in turn eat organic matter in the soil. But not only plants consume yeast waste products; the entire soil microcosm participates in this process. By introducing such fertilizing, we thereby activate the entire microflora, and it is as if a small storm of food chains is sweeping through the soil - some eat others, their excretory products serve as food for others and protect them from fourths.

As a big plus of all this, the metabolites of all this vital activity become available to plants as food. What they previously could not absorb from the soil, after feeding with yeast, it is given to them like dinner on a silver platter.

Of course, yeast, in the process of its life activity, consumes a lot of what is in the ground. For example, there is an opinion that they deplete the soil by drawing potassium and calcium from it. Yes, these elements are required for their nutrition, but they do not put it away and after their life they will also become someone’s food and all the elements will remain where they were, i.e. in the soil. Adding ash to yeast nutrition can serve as additional nutrition for them if these elements are not enough in the soil. And if you also take into account that the lifespan of yeast in the soil is very short, and does not exceed one day, then they will extract very, very little from the soil.

Yeast needs nitrogen and phosphorus in much larger quantities, but for some reason no one talks about this. Experienced moonshiners will support me; in order for the mash to ferment well, for every kilogram of sugar you need to add 2 grams of ammonium sulfate and 3 grams of superphosphate. Or, as an alternative, 4-5 grams of rotted chicken droppings or 1 ml of ammonia for every 2 liters of mash.

After the end of its life, the yeast will also become food. And this is very good food. For example, they contain 12% protein, the decomposition of which releases quite a lot of nitrogen, which is precisely a good nitrogen supplement. Therefore, the main purpose of yeast in the soil is to die there. Not right away, but that’s their fate.

And since a lot of nitrogen is released after them, it becomes clear when such fertilizing is recommended and when not.
