In agriculture, vermiculite can be used as soil conditioner. It develops the soil permeability and water content, makes acidic soil change into neutral soil. Exfoliated vermiculite plays a very good heat insulating effect, making the building warm in winter and cool in summer. In gardening, vermiculite can be used for flowers, vegetables, fruit cultivation, breeding and other aspects.
