Soil is the base where crops grow and develop. While organic substances are not only major material base for fertilizer supply and preservation in soil, but also the most effective constituent forming soil granular structure and preventing soil hardening.
Microorganisms are active organic substances in soil.
They improve soil physicochemical property, convert soil fertility, increase soil porosity, and accelerate active substance indispensable for soil maturation. Metabolic activity of microorganisms in soil are key to conversion of soil substances into energy. Through the key reaction of the combination, large amounts of various physiological active substances are produced, thus achieving the aim of improving soil fertility. At the same time, Yililai bio-fertilizer contains large amount of organic substances good to growth and multiplication of beneficial flora, thus effectively improving activity of beneficial rhizosphere bacteria. That is the scientific principle of using Yililai bio-fertilizer to improve soil fertility.
