What harm does sowing only use vermiculite to plant?
Vermiculite is a natural, non-toxic mineral that expands at high temperatures.
Agriculture, vermiculite can be used as a soil conditioner, because of its good cation exchange and adsorption, can improve soil structure, soil water storage, improve the permeability of soil and water, acidicto neutralsoil; vermiculite can also play a role of buffering, rapidchanges ofphtohinder,. Slow release fertilizer on crop growth medium, and allows a slightly excessive use of fertilizers and no harm to plants;
It is a relatively rare mineral, belonging to silicates, whose crystalline structure is monoclinic and looks like mica from its appearance. Vermiculite is produced by hydration of certain granite, which is usually produced simultaneously with asbestos. Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of the soil.
Vermiculite can also provide the crop with its own K, Mg, Ca, Fe, and trace amounts of Mn, Cu, Zn and other elements. Vermiculite has the characteristics of water absorption, cation exchange and chemical composition, so it has many functions such as fertilizer preservation, water retention, water storage, air permeability, mineral fertilizer and so on. The experiment shows that adding the expanded vermiculite of 0.5-1% into compound fertilizer can increase crop yield by 15-20%.
Horticulture, vermiculite can be used for flowers, vegetables, fruit cultivation, seedling raising, etc., in addition to potting soil and regulators, but also for soilless cultivation. As a nutrient base for growing potted trees and commercial beds, it is especially advantageous for the transplanting and transportation of plants. Vermiculite can effectively promote plant root growth and seedling growth is stable.
