The granular is milky white in color with two sizes: 1-2mm and 2-4mm. The compressive strength of 2kg and is made by mixing zinc sulphate powder into granules.
Absorbs moisture easily, dissolves quickly in water, and insoluble in propanol. The zinc content can be produced according to customer requirements.
Usage:
This product is mainly used in agriculture as a base fertilizer or water-soluble fertilizer to improve soil zinc deficiency. By adding zinc fertilizers to the soil in agriculture, plants can absorb and utilize zinc, which improves plant growth and yield, thereby increasing the intake of zinc in the human food chain.
