Zinc Sulphate Heptahydrate 21.5% & 22%

Zinc sulfate heptahydrate (ZnSO4·7H2O) is usually used as one of the trace element fertilizers to supplement the demand of plants for zinc. The following are the main uses of zinc sulfate heptahydrate in chemical fertilizers:
1.Zinc supplementation: Plants generally have a low demand for zinc, but it is one of the key elements for plant growth and development. Zinc participates in various physiological processes of plants, including plant growth, photosynthesis, fruit development, etc. By adding zinc sulfate heptahydrate to chemical fertilizers, it can provide the proper amount of zinc needed by plants, promote the healthy growth of plants, increase yield and improve quality.
2.Prevention and treatment of zinc deficiency: Some soils have low zinc content, or there are other factors that prevent plants from fully absorbing zinc, which may cause plant zinc deficiency. In this case, the use of fertilizers containing zinc sulfate heptahydrate can replenish zinc in the soil in time, effectively preventing and treating zinc deficiency in plants.
3.Soil improvement: Zinc has a certain soil improvement effect, which can promote the decomposition of organic matter and the release of minerals in the soil, and provide the nutrients needed by plants. In some cases, soil quality can be improved by adding fertilizers containing zinc sulfate heptahydrate, increasing soil fertility and water retention capacity.

NOTE: It should be noted that the use of zinc sulfate heptahydrate in chemical fertilizers should determine the appropriate application amount and application method according to specific crops and soil conditions. It is recommended to follow proper fertilization guidelines based on soil test results and plant zinc requirements to avoid over or under application.
