Large particle seedling substrate vermiculite improves soil mechanism, water storage and soil moisture conservation

Vermiculite can be used as a soil modifier. Because of its good cation exchange and adsorption, it can improve the structure of the soil, store water and preserve moisture, improve the permeability and water content of the soil, make the acid soil become neutral soil, and the vermiculite can also play a buffer role, obstruct the rapid change of the pH value and make the fertilizer in the medium of crop growth. It is slowly released and allowed to use fertilizer a little too much and no harm to plants; vermiculite can also provide its own K, Mg, Ca, Fe, and trace elements such as Mn, Cu, Zn, and so on.
