In the diet of each family in one way or another, there are eggs. When breaking them, do not rush to throw them away, because egg shells are an indispensable natural source of calcium. The unique ingredient is not only necessary for plants, but also perfectly absorbed by almost all types of horticultural crops. The composition of the shell contains a complex of trace elements and nutrients.
To obtain complete material, eggshells are placed in cardboard boxes and left in a dry place for drying in a natural way. It is necessary to first remove the residual protein and the inner matte film. After complete drying, it is crushed and put into paper bags, airtight jars or containers.
Advice! Do not use plastic bags for storage. The shell gains moisture and deteriorates.
The cooking process is carried out in stages:
- dried shells are laid out on the fabric and rolled out with a rolling pin,
- grinded in a coffee grinder or blender,
- folds into containers with lids.
There is another universal way. The shell is baked on an open fire and chopped together with wood ash. This fertilizer is even more effective for plants.
Advice! Using eggshells as drainage is an excellent solution for combining several tasks. This method will not allow water to stagnate, and the soil will receive the necessary additives.
For environmentally friendly products, the shell is indispensable, its use is obvious:
- promotes deoxidation of soil, is used for alkalization,
- an effective tool in the fight against pests and rodents,
- soil structure improves
- the process of adaptation is accelerated during plant transplantation,
- accelerating the development of the root system,
- restoration of air exchange,
- prophylactic against diseases,
- increase immunity
- enrichment of the soil with minerals and trace elements.
Reference! Some growers use shell halves to grow seedlings.
By harvesting such natural fertilizer for the future, you can not only save, but also provide almost all plants in the house and in the garden with fertilizing. Stocks can be stored for a long time. And do not worry about the dosage of dry shells introduced into the soil. Excess will not adversely affect the plants.
What does an egg shell consist of?
As for the chemical composition, it was deciphered back in 1980 by A. L. Stelle, a candidate of agricultural sciences. According to the results of the study, it consists of 93-95% of easily digestible calcium carbonate, the rest is magnesium, iron, phosphorus, aluminum, potassium and sulfur. And calcium and magnesium are the main components that are required for the normal development of plants. Moreover, these minerals lower the acidity of the soil, and also positively affect the composition and structure of the latter. Indeed, with high acidity, the fertility of the plot decreases, which negatively affects the yield and growth of most of the crops.
The chemical composition of the shell
Studies conducted by other scientists have shown that to normalize the level of acidity for each square meter of land, about 500 g of calcium carbonate is required (if the soil is more acidic or heavy, then 1 kg).
Important information! The shell has a crystalline structure, than this material compares favorably with lime or chalk. This is explained by the fact that such a structure contributes to a more rapid and intensive assimilation of trace elements.
Shell Collection Rules
How to collect the shell
For gardens, as a rule, the shell of eggs of domestic chickens is used. All nutrients in this shell are of natural origin, since village birds eat mainly natural food. But it is obvious that not everyone has access to such an environmentally friendly product, so you can use store eggs for these purposes (they also have enough calcium), although such fertilizer will be less effective.
Eggshell suitable for soil fertilization
It is recommended to stock up on shells in the winter, when the next laying season begins in chickens after a short break. At this time, the eggshell has the highest density, and more nutrients (especially calcium) accumulate when compared with the end of the season (May-September). It has also been observed that the shell of brown eggs usually has a greater thickness than white ones. Therefore, it weighs more, which has a positive effect on the concentration of beneficial micro and macro elements.
Also note that you can not collect the shell, which stuck pieces of protein or which has not been washed. Very soon it will start to smell unpleasant, and all the collected material will be discarded. To avoid this, the shell of raw eggs must either be washed or dried thoroughly.

Egg formation and shell quality
As for boiled eggs, only clean and well-behind shells should be taken from them. To determine the total weight of material that can be collected per year, the following formula is used:
in which A is the approximate weight of a shell from one egg (10 g), B is the number of eggs consumed during the month, C is the number of months. 10% is the number of shells to be discarded.
Boiled eggshells are not good
Important information! The shell of boiled eggs is best not to be used for feeding, since many elements in it disappear at elevated temperatures.
Egg shell as a fertilizer how to apply?
If you believe experienced gardeners, leaving reviews on thematic resources, then for effective recharge of 1 m? soil requires at least a hundred crushed egg shells. This, of course, is irrational, in connection with which other ways of using this natural fertilizer containing calcium were created. The most common methods are listed below.
Method number 1. Feeding indoor plants
Fertilizer for indoor plants
Such plants necessarily require additional top dressing, although many gardeners do not pay attention to the alarms sent by green pets. So, for flowers and other landscapers in enclosed spaces, the apartment environment is not favorable, especially in winter (lack of air, lighting and humidity). That is why it is necessary to apply various fertilizers. This can be not only store dressings, but also the eggshell considered in the article.
From the shells, for example, you can prepare an infusion. The action algorithm should be as follows.
Table number 1. Preparation of eggshell infusion
|Step 1. The shell is collected, washed with water and dried.|
|Step 2. Then it is carefully crushed and mixed with water (optional). The resulting mixture is infused for several days, from time to time it needs to be mixed, although you can use just a crushed shell.|
|Step 3. Egg powder or infusion is added to the soil.|
|Step 1. The shell is thoroughly washed and dried.|
|Step 2. Then it is crushed (no need to grind) and placed on the bottom of the pot. The resulting "cushion" will not only improve drainage, but also enrich the soil with calcium. The liquid will not stagnate, which will prevent the development of putrefactive processes.|
|Step 1. The shell is crushed in the same way as in the previous method. The edges should be coarse and sharp.|
|Step 2. The crushed shell crumbles around the plant. It is advisable to do this in circles.|
|Step 3. Its sharp edges will not allow pests to get to the plants.|
|Step 1. The shells of large eggs are washed and dried.|
|Step 2. At the bottom, make one small hole.|
|Step 3. Next, the shell is half filled with soil. |
|Step 4. The seeds are placed inside, sprinkled with a small amount of soil.|
|Step 5. You can also write the name of the culture on the shell, for which a marker is required.|
|Step 6. Inshell seedlings should be stored on the windowsill, periodically watering.|
