Marine fishing: Fishing for bait.

Other aspects: adsorbent, filter aid, active carrier of chemical products and fertilizer, sewage treatment, seawater oil adsorption, cigarette filter, explosive density regulator.

In agriculture

In agriculture, vermiculite can be used as a soil amendment, because of its good cation exchange and adsorption, can improve the structure of the soil, water storage and retention, improve the soil permeability and water content, acid soil into neutral soil; Vermiculite can also play a buffer role, hinder the rapid change of PH value, so that fertilizer is slowly released in the crop growth medium, and allow slightly excessive use of fertilizer without harm to the plant; Vermiculite can also provide crops with K, Mg, Ca, Fe and trace amounts of Mn, Cu, Zn and other elements. The properties of water absorption, cation exchange and chemical composition of vermiculite make it play multiple roles such as fertilizer preservation, water retention, water storage, air permeability and mineral fertilizer. The experiment showed that 0.5-1% of expanded vermiculite was added into the compound fertilizer, which could increase the crop yield by 15-20%.

horticultural

Horticulture, vermiculite can be used for flowers, vegetables, fruit cultivation, seedling and other aspects. In addition to being used as potting soil and conditioner, it is also used for soilless cultivation. As a nutritious base for growing potted trees and commercial seedbeds, it is particularly beneficial for transplanting and transporting plants. Vermiculite can effectively promote the growth of plant roots and the stable development of seedlings. Provide water and nutrients necessary for plant growth for a long time, and keep the root sunlight temperature stable. Vermiculite can make crops from the early growth can obtain sufficient water and minerals, promote faster growth of plants, increase production.
