It is available in granular and powder forms and is designed for two core applications: soil remediation and aquaculture water quality improvement. It can also be used as an animal feed additive.In soil, it adsorbs and passivates heavy metals, loosens compacted soil, regulates the rhizosphere, promotes beneficial microorganisms, supplements calcium, magnesium, boron, and silicon, improves fertilizer use efficiency, suppresses nematodes and soil-borne diseases, delays senescence, and improves yield and quality. In aquaculture, it stabilizes pH, buffers acid-base fluctuations, supplies calcium and magnesium for shrimp and crab molting and shell hardening, purifies water, improves sediment, and inhibits harmful bacteria and black odorous bottom.
