Vermiculite is a natural, inorganic, non-toxic mineral that expands under the action of high temperature.In agriculture, vermiculite can be used as a soil conditioner. Because of its good cation exchange and adsorption properties, it can improve the structure of the soil, store water and retain moisture, and improve the air permeability and moisture content of the soil. In horticulture, vermiculite can be used in the cultivation of flowers, vegetables, fruits, and seedlings. As a nutrient base for planting potted trees and commercial seedbeds, it is particularly advantageous for transplanting and transporting plants.
