Seasoned vegetable gardeners never throw away eggshells, as they can double your harvest .

How to use this useful fertilizer correctly, said agronomist Ivan Russkikh on his Zen channel.

How to use eggshells as fertilizer

Eggshells are a unique source of calcium and some other trace elements needed by plants, but due to their dense structure, they dissolve slowly in the soil.

The simplest way to use the bark as an antioxidant fertilizer is to grind it into a flour similar to dolomite flour. Even in this form, however, it becomes active only at the end of the season or the following year.

The action of the crust can be accelerated with phosphate mobilizers, but it is much easier to make a ‘fast calcium’ fertilizer.

Pour two liters of 9% vinegar into a three liter jar and put the peels in there as they come.

As the peels dissolve, foam forms, so do not fill the jar completely with vinegar and put all the accumulated peels at once.

Fertilizer is used as follows: dissolve a glass of fertilizer in 5 liters of water and water 0.5-1 liter per plant. Tomatoes, peppers, cucumbers, eggplants and cabbage like this fertilizer.

You can also use citric acid as a solvent (a tablespoon of citric acid per one and a half liters of water).
