Second, the main purposes:

Agriculture: vermiculite can be used as soil conditioner, because it has good cation exchange and adsorption, can improve soil structure, water soil moisture, improve soil permeability and water content, so that the soil becomes acidic neutral soil; vermiculite can also cushion and hinder the rapid changes in PH value, so that fertilizer in slow release of plant growth media, and allows slightly excessive use of fertilizers is not harmful to plants; vermiculite can also provide self-contained to the crop of K, Mg, Ca, Fe, and trace amounts of Mn, Cu, Zn and other elements. Vermiculite absorbent, ion exchange and chemical composition characteristics, it plays a fertilizer, water, water, ventilation, and the multiple role of mineral fertilizers. Results show that: the 0.5-1% of the expanded vermiculite mixed with fertilizer in crop production could increase 15-20%.

Gardening: a horticultural vermiculite, and its main role is to increase the soil (media) of the aeration and water retention. Because of their fragile, with the use of time, tends to lose the dense medium aeration and water retention, so thin coarse vermiculite to use than a long time, and the effect is good. Therefore, the horticultural vermiculite should be selected coarse vermiculite flakes, even planting a small seed sowing medium and as a cover, are to thick for good.

Livestock: the expanded vermiculite has a unique structural characteristics and surface properties, as well as non-toxic, sterile and chemically inert, can be used as carrier, adsorbent, fixing agent, and feed additives.
