Description
Zinc is an essential component of plant hormones (such as auxins) and can activate more than 300 enzymes, closely related to nitrogen metabolism in plants.
Through citric acid, it fully chelates metal elements with organic active substances, exhibiting moderate chelation strength. This allows for the slow release of citric acid, metal ions, and organic active substances within the plant, resulting in a significant slow-release effect and high absorption and utilization rate.
With a zinc content (>20%) higher than EDTA zinc sodium, the required dosage can be reduced by 30%. It boasts high effective components, low molecular weight, and easier absorption, making it an ideal substitute for EDTA zinc sodium.
The slow release of citric acid and organic active substances can regulate the soil pH to a slightly acidic level, promoting a soil environment conducive to beneficial microbial activity and good soil aggregate structure, resulting in significant soil improvement.
All raw materials used are food-grade, with low heavy metal content, posing no harm to the environment. It is non-toxic and harmless, making it more environmentally friendly.
