EFFECT OF "BIST" AND "BIST-M" BIO-PREPARATIONS ON CHANGES IN THE AMOUNT OF NITROGEN, PHOSPHORUS AND POTASSIUM RECEIVED BY PLANTS IN THE SOIL

It has been shown that salinity, which occurs in the case of agricultural practices, occurs when the amount of salts formed in the root system of the plant is low, and the amount of drainage water is low. The problem of low productivity of saline soils is explained not only by the toxicity of salts or the damage of plants by excess salt in the root tissues, but also by the lack of organic and mineral substances, especially N, P and K.
