The value of eggs is not only in their nutritiousness and usefulness, but also that this product is waste-free. Gardeners successfully use egg shell as the organic fertilizer increasing fertility of the soil.
During forming of egg the organism of adult bird asks for the help secondary skeletal system: thin fragments of bones resolve, releasing calcium, magnesium and phosphates. At the expense of it around egg the shell for 95% consisting of carbonates of the calcium which is almost completely acquired by living organisms is formed.
Also the shell contains potassium, magnesium, sodium, silicon, organic protein, small amount of fats. Such content of useful substances does shell by the real mineral complex irreplaceable for fertilizing of plants and improvement of condition of soil.
The increased acidity of the soil has an adverse effect on its fertility and efficiency of the plants growing there. The most available, inexpensive and effective way of neutralization of excessive acidity – entering into the soil of egg shell. It is necessary to use shell only from crude eggs since during cooking of egg calcium collapses and it becomes almost useless. The shell is carefully washed out, well dried up and crushed manually or by means of the meat grinder, the coffee grinder.
Powder from shell is brought in the soil at its digging up or landing of plants, adding fertilizer directly to hole. For neutralization of excess acidity of the soil enough 0.5 kg of shell on 1 sq.m. Besides, it is possible to add such fertilizing to soil, having mixed it with wood ashes which are good converter of excessive acidity and potassium-phosphorus fertilizer too. It is important to remember that the shell decays in the soil long time and the surplus of calcium can negatively affect development of seedling therefore it is better to feed up the calcinated powder only adult plants, and for seedling to use the dosed liquid fertilizing. For preparation of liquid fertilizing the shell is put in glass capacity, filled in with boiled water and insisted several days to condition of turbidity of water. Before use solution is diluted with water in the ratio 1:3. It is possible to water with such fertilizer both houseplants, and garden, eggplants, pepper, beet, root crops, cherry, plum, roses treat such fertilizing especially favourably. Halves from shell it is possible to be used as original and useful container for cultivation of seedling. Are filled in Skorlupki by nutritious soil mix and are sowed by seeds of plants. After germination and strengthening of seedling the shell is crushed and together with earth lump the sprout is landed to the open ground. In order that in "container" there was no stagnation of water and rotting of young backs, it is necessary to do in the lower part of shell sharp needle or needle several holes playing role of drainage holes.
