The zealous owner throws in a lot of waste. And our summer resident finds use for every trinket. Not many eggshells are thrown away in a year, but many collect and hoard them to use in the garden. Whether this makes economic sense, everyone decides for himself.
What is the value of eggshell as fertilizer
This is not to say that the eggshell is a complete fertilizer, but it contains many useful components. It is about 90% calcium carbonate, the same substance as natural chalk or limestone. Therefore, the use of shells in crop production makes sense, especially on acidic soils. The remaining 10% account for impressive list elements, including those very necessary for plants.
So, 100 g of raw shell contains 80 mg of potassium, 400 mg of magnesium, 150 mg of phosphorus, as well as copper, molybdenum, zinc, cobalt, etc. Is it a lot or a little? If the shells could be accumulated several kilograms, it would be a full replacement for purchased mineral fertilizers. In real life - a useful addition to them. But if there is an opportunity, why not take advantage of it?
The composition of the shell depends a little on its color and origin, but the approximate figures are the same
The main point in using shells is to lower acidity and improve the mechanical characteristics of the soil. To put in order the acidity on unsuitable soils, 1 m 2 must use a shell of at least fifty chicken eggs... Of course, it is easier to add lime, but ... A normally crushed shell is also a loosening agent of the soil, contributing to the flow of oxygen to the roots, but do not forget about trace elements!
The shell is also used as protection against many pests: if you grind it not very finely, then with its sharp edges the shell scratches the delicate skin of slugs, wounds the insides of the bear. Prevents the shell and the spread of some plant diseases developing in the ground.
How to use the shell
It is almost impossible to harm plants with eggshells (except for those who love acidic soil!). Nevertheless, it is necessary to prepare fertilizer and use it correctly so that the work does not go down the drain.
Shell harvesting
The maximum benefit will be when using shells from raw eggs: after cooking, many trace elements will pass into the water. In the shell boiled eggs, in fact, only calcium will remain of the useful components, and it is hardly worth spending time on its preparation. With the shell of raw eggs proceed as follows.
Variants of use in the vegetable garden, garden and for indoor plants
If the eggshell is used as a fertilizer, it is added to the soil during digging or the plants are fed with infusion (powder is poured hot water, after a day filter and water the beds). For example, under cabbage or melons, when planting, a teaspoon of powder is added to the hole. Under berry bushes in spring, a handful of crushed shells are buried shallowly into the soil. Annual flowers, onions, beets, legumes are watered with shell infusion 2 times a month.
You should not use the shell when growing those plants that grow on slightly acidic soils: hydrangeas, petunias, ferns, basil, sorrel, etc.
In indoor floriculture, you also need to be careful. Many flowers prefer acidic soils, so no shells are used for them. These are, for example, gloxinia, pelargonium and all types of violets.
For other indoor flowers, a lot of shells are not required. So, when planting on a standard pot, they take, mixing with the soil, no more than half a teaspoon of powder. Once a week, flowers are watered with a diluted infusion. For this, 2 tbsp. spoons of powder are poured into 1 liter of boiling water and insisted for 5 days, after which they are filtered.
In addition to being used as a fertilizer and soil deoxidizer, eggshells are used for the following purposes:
Eggshell - a valuable source of trace elements and a good soil deoxidizer. If used correctly, it saves money and improves the structure and fertility of the soil both in the garden and in pots for indoor plants.
and other fertilizers in the topic https://vk.com/topic-39798796_31678078
Eggshells can serve to increase soil fertility and can be of great benefit. Gardeners and gardeners use eggshells as an effective trace element and deoxidizing additive to the soil.
In terms of composition, the eggshell consists of 92-95% calcium carbonates (and this calcium carbonate is absorbed almost one hundred percent due to the fact that the poultry body has already been synthesized from organic calcium into inorganic),
* 1-3% from magnesium carbonates, 1-2% phosphates and
* 3-4% organic matter. And as you know, calcium and magnesium are absolutely essential nutrients for plants, right after nitrogen, phosphorus and potassium, in addition, they deoxidize the acidic soil of the Non-Black Earth Region and improve its structure. Excessive acidity reduces the fertility of the land, negatively affects the development and productivity of many plants.
In addition, the shell of eggs has a different crystalline structure than lime or chalk, so the pieces of the shell are quite well "absorbed" by the soil. Therefore, the shell is very useful for the garden.
The eggshell contains calcium carbonate, which can be used as a lime fertilizer.
To start the action of the shell faster, it needs to be crushed.
METHODS OF APPLICATION OF EGG SHELL FOR GARDEN AND GARDEN
Egg shells for the garden can come in handy when growing seedlings. Back in the last century, when pots for growing seedlings were not on sale, resourceful gardeners took clean eggshells, filled it with fertile soil and sowed vegetables and flowers in it. When the seedlings grow, the shell is crushed and the seedlings are planted from the ground along with the shell. At the same time, it is also one of the ways to replenish the supply of nutrients in the soil.
FOR SEEDLING
Dry shells are placed in a jar, tamped, and can be ground into dust in an electric meat grinder. Take a crushed shell from 4-5 eggs, pour a liter of boiling water, insist for 5 days. stirring daily. Watering seedlings of peppers, eggplants, asters, beets, roses, indoor flowers. You can add coarsely crushed shells to the seedling bowls as drainage. In the garden, the shell powder applied to the garden bed gently deoxidizes the soil and improves its structure. Dose: 1-2 glasses per 1 square meter. This powder can be used to powder seedlings of flowers to protect them from the "black leg".
SOIL ACIDITY
More accurately, you can determine the acidity of the soil using an agrochemical laboratory. But that will take a lot of hassle. I myself determine the acidity of the soil on my summer cottageusing a simple technique. I take a small amount of crushed soil from the area to be tested and pour it into a bottle for feeding babies until the second division from the bottom. Then I pour water to the fifth division and pour half a teaspoon of powdered chalk, and put a tightly rolled nipple on the neck and shake it vigorously for 2-3 minutes. When chalk interacts with soil, carbon dioxide is formed. The pressure in the bottle rises and the nipple expands. With weak acidity, it straightens slightly; the higher the acidity, the more the teat takes on its original shape.
AS A FERTILIZER
Eggshells are known to consist mainly of calcium, which is a fertilizer, but not as essential as nitrogen, phosphorus, and potassium. A significant benefit from it (if well ground) will be when applied with mineral fertilizers. The fact is that most of they are increased by the acidity of the soil, and the addition of shell powder neutralizes the acidity, which increases the efficiency of fertilizers.
HOW TO SUPPLY
But nevertheless, since the shell contains calcium and a set of various trace elements, necessary for plants, it is more expedient to introduce it under those crops that most often lack micronutrient fertilizers. For instance, cauliflower will certainly appreciate such a top dressing introduced into the hole during planting. It is best to grind the shells before use. It will not hurt to pour boiling water over it before this.

An impressive part of the products from our table contains the elements necessary for the development of plants and is deservedly used in the form of a fertility vitamin. One of the available and easy-to-use products is shells. Rich and healthy harvest provided for gardeners, who knows how to use eggshells as fertilizer, top dressing and protection and who knows how to make a vitamin cocktail out of it for the garden.
Elemental composition and benefits
The outer shell of bird eggs is a natural source of calcium carbonate, an element that is easily and quickly absorbed by plants. The calcium content in the shell of the egg exceeds 90%.
The enrichment of the soil with the listed microelements reduces its acidity and makes it friable, which leads to an increase in fertility. This is one of the reasons for using egg shells for vegetable gardens, gardens and indoor plants.
It is recommended to collect the shells of eggs not exposed to heat treatment... It contains all the elements necessary for soil nutrition. Effectively using chicken and quail eggs, their shell lends itself easily to mechanical processing, and the useful elements contained in it are well absorbed. The shell of the used egg must be rinsed to remove protein residues... If the conditions for drying the shell are optimal, then the remaining protein will not become a source unpleasant odor.
The shells should be dried in a dry, warm place. It's better to put them in paper bags, carton boxes, plastic pallets. Dried shells can be slightly crushed and stored in any container. Storage containers should not be tightly closed. Convert collected material to powder should be before use.
You can grind the shell into powder using a blender, meat grinder, coffee grinder. It is convenient to grind small portions in a mortar. Many housewives put the shells in a tight bag and rub them with a rolling pin.
Fertilizer form and applications
As a fertilizer or top dressing, the shell is used in the form of powder and infusion. It is also used as protective agent from pests. The method of using the shell depends on the degree of its crushing.
Seedling growth stimulant
The shell is ground to a state of flour and is used when transplanting seedlings into open ground... Pour 1-2 teaspoons of powder at the bottom of each hole, plant a seedling, cover the hole with earth. Egg fertilizer in the form of a powder, it dissolves quickly, releases nutrients into the soil and makes it less acidic. Egg flour can be sprinkled on the ground around the stem of the plant, this is the prevention of the disease "black leg".
Top dressing, nutritious pots
Uncrushed shells are used to prepare nutritional infusions. The halves are used as eco-pots for seed germination. Make a drainage hole from the bottom of the dried shell with a needle or awl. Fill egg containers with soil and plant flower or vegetable seeds, no more than 2-3 pieces per 1 shell. The soil will receive nutrients from the egg shell. When transplanting seedlings, it is enough to carefully split the pot so as not to obstruct the root of the young plant.
Reliable drainage and protection
The shell in the form of small pieces is a good barrier to garden pests... It is sprinkled with the aisle, if the supply of eggs allows, then it can be sprinkled around each plant. The sharp edges of the shell are an obstacle to slugs and snails. Shells small size used as drainage for soil, they can be laid at the bottom flower pots and put into the wells of plants. Such drainage makes the soil loose and does not form a crust with capillaries on its surface, through which moisture intensively evaporates. Due to the low decomposition rate, the egg drain works for several years.
Natural vitamin of fertility
Fertilization can be done in several ways, but the result of application is always the same - a healthy and disease-resistant plant.
For a decent harvest, you should know how to use eggshells as fertilizer and for which crops.
A positive result is brought by feeding with an infusion of withering and diseased indoor plants. Treatment should be carried out 1-2 times a month. A small amount of fertilizer is applied before watering the plant. It is not recommended to use the solution for healthy flowers. The infusion is used with caution to fertilize seedlings.
- They love watering young peppers, eggplants and tomatoes with an egg solution.
- Calcium is required for stone fruit crops - cherry, plum, bird cherry.
- Bushes and trees need fertilization with infusion - raspberries, currants, gooseberries, apple trees, pears, apricots.
- Egg infusion increases the yield of strawberries and strawberries.
- All varieties of onions, broccoli, beets, lettuce, melon, pumpkin, watermelon. - crops for which eggshells are indispensable as fertilizer.
Many crops thrive on heavy, acidic soils and do not tolerate excess calcium. In this case, not applicable eggshell as fertilizer... For which plants you should not use egg vitamin: for seedlings of strawberries, cucumbers, spinach and beans, as well as for indoor flowers - hydrangea, gloxinia, violet, azalea, gardenia and pelargonium.
Fertilizer for the garden or flower food from eggshells will be more effective if you add to it the husks of onions, garlic or ash. Good results bring sharing chemical and organic nutrients of soil and plants.
Attention, only TODAY!
Eggs are included in the diet of a healthy person. And not only chicken. Many people prefer quail, someone adores goose, and someone prefers exotic ostrich. One way or another, the contents of the eggs are eaten, and the shells are often simply thrown away. According to statistics, a family from three people consumes up to 800-900 chicken eggs per year. If a average weight one shell - 10 g, then during the season you can accumulate up to 8-9 kg of eggshell.
Is it a lot or a little? If you want to use effectively the substances in the shells, then not so much! It is estimated that, depending on the degree of acidity of the soil, from 0.5 kg can be introduced into it. up to 1 kg. for every square meter surface.
In general, pure calcium is a metal; in nature, calcium compounds are more common - bicarbonates and salts formed from it. These salts are the components of limestone, chalk, and also the shell of any eggs. Calcium carbonate occupies up to 95% by content in the composition hard shells eggs. In addition, another 27 elements of the periodic table are present in it. These are magnesium carbonate, magnesium phosphate, phosphorus, potassium, iron, aluminum, sulfur. In percentage terms, they occupy a very small part, but with constant fertilization, they will also not go unnoticed.
The films that accompany the shells themselves from the inside are rich in organic matter. Mostly mucin and keratin.
The structure of calcium bicarbonate present in large quantities in shell, differs from the structure of the received chemically chalk.
PLEASE NOTE: Since the shell is created by nature itself, calcium salts have a completely different crystalline form, which is better absorbed by plants.

Why shells are good for plants
The shell of eggs, ground and in water infusions, will benefit your garden, especially if it is located on clay, heavy and acidic soils, as it contributes to:
- deoxidation of the soil. All over the world, soils with a pH of 5.5 to 7 are considered fertile. Only at these values \u200b\u200bcan the nutrients surrounding the plant roots dissolve and these vital materials for photosynthesis and growth can be absorbed. And if the value of the level is 5, then this means that the soil is highly acidic, toxic to many plants and it is necessary to reduce the acidity by 100 times in order to lower this figure to an acceptable 6;
- enrichment with minerals;
- increasing soil looseness. Areas allotted for vegetable gardens are often clayey, heavy in structure. This (in addition to acidification) does not allow air to enter the root system, leads to stagnation of water in the soil, and when the weather changes - cracking of the soil and breaking off the roots. The introduction of eggshells significantly improves the aeration properties of the earth;
- scaring away pests (bear, slugs, moles). While powder can be used for slugs and snails, it is recommended to use large pieces of shells for bears, shrews and moles. You can only break it slightly with your hands. The sharp edges of the hard shells will interfere with the spread of pests;
- protection against certain diseases (black leg, apical rot).
Methods for using eggshell
The shell, crushed to a powder state, can be:
- just fill in the soil and then close it with a rake. This can be done both before and after planting, it is very useful to add to the holes for potatoes and onions;
- sprinkle over the ground to protect against cruciferous flea beetles, clutches of cabbage butterflies, reduce weed growth and mulching;
- use in decoctions and infusions for watering.
Finely crushed shells can be scattered by hand, but it is more rational to make a special device: plastic bottle evenly make small holes through which the powder will pour out onto the surface of the beds.
Shallow perimeter embedding is useful for trees. trunk circle in order not to damage the roots.
To use beneficial features shell film, you can make infusions from the shell without removing this film.
Usually, one to two weeks is enough for the water, into which the untreated shell will be dipped, to become cloudy and emit a specific smell of hydrogen sulfide. This means that the infusion is ready and you can water the plants with it. Take from 5 to 10 shells for 1 liter of water. The finished solution can be diluted with water during watering up to 10 times.
We collect and store the shell correctly
Those who have tried to collect the shells will immediately note the only drawback of this process - the smell, which over time begins to emit organic protein residues on inside shells and thin films remaining inside. We recommend two ways to safely collect and store the shells:
- with rinsing under running water in order to get rid of organic particles and the films themselves;
- roasting in the oven as the shells accumulate.
If you thoroughly wash the shells, you will get a positive side - the ability to dry future fertilizer without any inconvenience associated with odor. But also negative side will consist in the fact that you will not be able to count the useful substances contained in the films themselves.
The second option is more troublesome, since it will be necessary to warm them up on a baking sheet or in a patch as the shells accumulate. But it will be much easier to crush and grind the shells.
Every gardener transforms tough and hard shells into useful lime dust in his own way:
- can be scrolled through a meat grinder;
- do it fairly quickly with a coffee grinder;
- just crush with a crush manually;
- wrap in a tight canvas bag and beat with a hammer.
You can store already dried shells for a long time. Preferably not in polyethylene, but in paper bags or glass containers that are not tightly closed. The potential plant balm you have prepared should not suffocate.

For which plants can shells be used as fertilizer
As you know, each plant has its own individual preferences. Some of them like more acidity of the soil, some less. Therefore, trying to feed the infusion from the shells or pour the crushed powder from them into the ground to violets (Saintpaulia usambara) is not only useless, but even harmful.
Do not add excess alkaline additives to the planting of asters. Seedlings of tomatoes, peppers and eggplants are more likely to be pleased with watering from shells than directly applying it to the substrate.
But they will respond very positively to the introduction of the shell into the ground:
- leaf salad;
- all types of cabbage;
- radish;
- swede;
- pumpkin;
- watermelons, melons;
- greens (parsley, dill, celery);
- legumes (peas, beans, beans);
- stone fruit crops (cherry, plum);
- pome trees (apple, pear);
- bushes of raspberries, currants, gooseberries;
- citrus and conifers.
Important nuances
To find out which soil prevails in your area, you can use the official method: take samples and take them to a laboratory, where, after research, you will be given exact numbers.
IN recent times indicator tapes became popular. A strip of such a tape is moistened with damp earth and the acidity indicators are immediately determined.
But there is a faster and affordable way: about 50 g of earth is collected in a bottle, topped up with water to 200 ml. A compressed (rolled) rubber nipple (finger pad) should be used instead of a cover. After a few minutes of vigorous shaking, bubbles from the chemical reaction will begin to form in the bottle. If at the same time the rubber on the teat stretches a little, then the soil is weakly acidic. But if gas formation is strong, then most likely you will not escape liming.
Soil neutrality will be said:
- clover;
- chamomile;
- mother and stepmother.
Acidic soil is indicated by:
- plantain;
- horsetail;
- Ivan da Marya;
- mint.
Alkaline will grow:
- mustard.
DON'T FORGET: one shell for good development garden plants is not enough!
The shell can be combined with purchased fertilizers, or you can combine this natural delicacy with the same natural fertilizerslike onion peels, ash, banana skins, orange peel, nettle, shells walnut, potato peelings... There is evidence that the potato did not get sick and grew large and even if ash, shells were added to the holes during planting. onion skins dry.
It is better to make decoctions (infusions) from banana skins and zest of any citrus fruits. For example: 10 eggshells and the zest of 2 oranges are crushed, boiled for about half an hour in 3 liters of water, after insisting and cooling for several hours, you can water not only seedlings, but also any houseplantssuffering from a lack of fertilizer, especially in the spring.
Video - using eggshells as fertilizer for the garden
To obtain a high-quality and rich harvest, everything cultivated plants need constant care, loosening, watering and fertilization. There are many varieties of fertilizers, both chemical and organic, but not all of them are available. One of the types is eggshell, which contains great amount useful elements, but the main thing is calcium.
Article outline
Everyone has eggs in their diet, which are used not only for direct appointment, and for different kind baked goods. On average, according to statistics, a family of three uses up to 1,000 eggs per year (this can get 10 kg of potential fertilizer, if the calculation is made on the assumption that the average weight of one shell becomes 10 grams). The volume, of course, is small, but taking into account the purposes and for what it is used, this amount may be sufficient.
Eggshell composition
The shell is 95 percent crystalline calcium carbonate, which is well absorbed by the soil and all plants. In addition to calcium, the eggshell contains many other elements, such as iron, sulfur, potassium, manganese, magnesium, phosphorus. And the films inside the shell are rich in organic matter, with a predominance of mucin and keratin.
Thanks to a large number calcium contained in the eggshell, favorable processes occur in the soil that affect the growth and fruiting of plants.
Calcium functions
- Thanks to calcium in the soil, the vital activity of microorganisms is activated, which release nitrogen from organic matter and accelerate the decomposition of organic components.
- Calcium affects the acidity of the soil, reducing it to the required level, as well as improving the structure of the soil.
- Promotes better dissolution of all nutrients in a humid environment.
- Also, thanks to calcium carbonate, the immunity of plants increases, which is not only necessary to combat various diseases, but is also needed for easy adaptation to other conditions. external environment - this primarily applies to seedlings (during the period of planting in open ground).
- There is an activation of nodule bacteria in the process of soil deoxidation, which help to retain nitrogen in the root zone.
- And one of the main properties of calcium is the strengthening of the vascular walls, along which the movement of useful components necessary to accelerate the growth and development of the root system occurs.
Applying powder from eggshells increases soil friability. This is especially true in vegetable gardens with clay soil... This is necessary for the supply of air to the root system, since its access is minimal on heavy soils.
Also, when using the shell, the earth is enriched with useful minerals that are in its composition.
The shells can be used not only as a fertilizer, but as a means to protect against harmful insects such as a bear, slug and even a mole. To get rid of slugs, eggshell powder is used, but for bears or moles, it will be enough only to break the shell into small pieces, so that its sharp edges will prevent the further spread of pests.
The shell powder helps to prevent diseases such as top rot, black leg.
Even for indoor crops eggshells are beneficial not only as fertilizer, but also as drainage, when transplanting flowers into different pots.
Eggshells are used for different purposes and different ways, consider some of them.
Nowadays, special cups for seedlings are more and more in demand, which, when the plants are ready and planted in the ground, are dug in with them. After that, in the process of watering them, the cups become limp and do not interfere further development root system. By the same principle, you can use eggshells. Having made small pots out of the halves, having covered the earth there, you can start growing seedlings in them.
When the time comes for planting in the ground, it will be enough to crush or break the shell a little, and after dropping all the contents into the ground, the shell will serve not only as an additional fertilizer, but also as protection from pests.
In order for the absorption of calcium to occur as quickly as possible, you can prepare a water infusion on eggshells. To do this, you need to pour egg material into the container, which can be either in powder or as a whole. All this must be filled with water and allowed to infuse for a week. There are no proportions for this solution, it all depends on the presence of the number of shells and the required volume of the fed area.
The more shells there are, the more effective the solution will be, but the approximate proportion of shells to water is 1: 3. Before pouring the shell into the container, it is recommended to wash it, thereby preventing souring of the future solution.
How to make eggshell solution
Applying eggshells for compost
Each gardener has on his site compost pit for cooking organic fertilizer from a variety of waste such as weeds, tree foliage, food waste, and so on. To obtain a more effective and complex fertilizer, manure, ash and even sometimes are added to the compost layers. mineral fertilizers... So eggshells will play an important role in the quality of cooked humus, thanks to their useful functionswhich were discussed above.
Most home-grown plants, whether seedlings or indoor flowers, need good soil and drainage to avoid stagnant water and soil acidification. Usually expanded clay or crushed stone is used as drainage, sometimes foam or brick chips... Eggshells are an excellent drainage agent for indoor plants.
To use the shell as a drainage, it does not need to be crushed - it will be enough to crush it a little and lay it on the bottom of a pot or other container for planting. With a slight crush, the air gapthrough which liquid and air will pass, which have a beneficial effect on plant growth. Also, in this case, the shell will play not only the role of drainage, but also perform the functions of organic fertilizer.
Eggshells have many beneficial elements, thanks to which there is an active growth of plants, not susceptible to numerous diseases. Therefore, the shell is used both as the main fertilizer and as a top dressing. Before applying, the main condition for its effective effect on the soil and plants is crushing the shell into powder.
In this form, the shell is absorbed faster. And when it is invested in the land in large fractions, the decomposition process will take a long time and, as a result, the benefits from it will not come soon.
- To prepare the powder, it is necessary that the shell is well dried, and preferably fried in the oven.
- In order for the shell to be dry, after collecting it, it must be washed and put to dry in a dry and warm place... You do not need to rinse, but then there is a possibility of an unpleasant odor during long-term storage.
- It is necessary to store it in a dry and warm place so that moisture does not occur, which will hinder the grinding process.
- In order to grind it, you can use a meat grinder or coffee grinder. The following method is also popular: by wrapping the shell in a strong fabric, knock on the fabric with a hammer or other heavy object. You can also use a regular bucket and a stick with a diameter of at least 5–7 mm - once you put the shells in the bucket, you will need to crush it with this stick until you get the desired result.
If all the rules were followed when collecting the material, the powder will turn out to be very fine, without residual coarse fractions.
Once the powder is prepared, it can be stored long time subject to certain standards. So, in order for the shell to retain its properties and not deteriorate, the following rules must be observed:
- The container for storing the powder should not be closed too tightly for air to pass through.
- If a suitable container is not available, paper bags can be used.
- Do not use plastic bags.
- The storage area for eggshells should be dark and dry.
For which crops is eggshell fertilizer suitable
Each plant has its own individual needs, which depend on the quality and type of soil or on their growing season. For example, in one period more nitrogen is required, and during flowering and ovary - potassium and calcium. It is also worth knowing that for some plants, for example, violets, fertilizer from the shell can be harmful, and for example, such feeding will be useless for asters.
But there are plants that respond positively to this fertilizer, these include:
- tomatoes;
- pepper;
- radish;
- eggplant;
- cabbage and all its varieties;
- greens (lettuce, parsley, dill);
- pumpkin;
- melons and gourds;
- legumes;
- stone fruit trees;
- shrubs.
How and how much to fertilize from the shell
The shell fertilizer can be applied at any time and in different ways.
- During the spring or autumn digging vegetable garden - scatter eggshell powder over the plow, then cover it with earth at a depth of 10-15 cm. There is no specific application rate, it all depends on the amount of powder. The main advantage of this fertilizer is that if it is oversupplied, it will not harm the plants.
- The next way is feeding plants with prepared solution... Its preparation is very simple, you need to fill the shells with water and leave for 5-7 days to infuse. The resulting mixture, if it is concentrated, must be diluted with water about 1 to 2.
- Adding shells in any form (both in powder and in pieces) directly into the wells of plants - so you not only fertilize the plants, but also protect them from pests such as a bear or a mole.
- Powder not too crushed can be added in the spring and summer as mulch and to protect cabbage or other crops from slugs.
But with all positive qualities this fertilizer will not be enough for the full development of crops, therefore it must be used as an additional fertilizing with other mineral or organic fertilizers.
The shells can be added to fertilizers such as ash or bread, but the best option shells will be used to obtain organic fertilizer using composting, since not only shells can be put into compost, but also many other useful components.
Conclusion
Summing up the above, we can say that egg shell fertilization plays a large role in the growth garden cropsdue to the predominant element calcium carbonate. Also, this fertilizer is useful in that it contains many other elements necessary for plant growth.
The main functions of this fertilizer are soil deoxidation (as a result of which its structure improves), strengthening of plant vessels (along which all useful nutrients). Also, eggshells strengthen the immunity of plants, which helps to fight a variety of diseases. Eggshells can be used both as a pest control agent and as drainage or molds for growing seedlings.
The advantage of the shell is its safety (fertilization from eggs does not harm even with an excessive amount). AND main drawback shell fertilizer is that it cannot be used as the main one - for good harvest the shell must always be used together with mineral or organic fertilizers.
