The Uses of Zinc Chloride in Agriculture

Nov. 12, 2021

Zinc is one of the essential trace elements for plants. Zinc is absorbed by plants in the form of the cation Zn2+. The mobility of zinc in plants is moderate. Zinc indirectly influences the synthesis of growth factors in crops, and is also an activator of many enzymes that help photosynthesis; also the application of zinc fertilizer enhances the resistance of plants to stress. Basic zinc sulfate, zinc chloride, zinc phosphate, zinc oxide, and zinc lignin carbonate can be used as zinc fertilizers.

With the growing awareness of zinc and the rapid development of new fertilizers, the development of zinc fertilizer is bound to be objective. The development of zinc fertilizer in China is also progressing steadily.

The Uses of Zinc Chloride in Agriculture

Physiological functions


Zinc mainly constitutes enzymes and plays its important active function. Zinc is irreplaceable as the active core element of many enzymes. The distribution of zinc-containing complex enzymes found so far has reached 59 species in six major categories, including oxidoreductases, transferases, hydrolases, cleavage enzymes, isomerases and synthases. Zinc can also activate oxaloacetate oxidase, enolase, etc. Therefore, zinc plays an important role in photosynthesis, respiration, nitrogen metabolism, hormone synthesis and plant growth of crops.  

(1) Zinc is a component of carbonic anhydrase, which promotes the release of carbon dioxide and accelerates its passage through lipid membranes into chloroplasts and provides substrate for ribulose diphosphate carboxylase.  

(2) Zinc inhibits the activity of RNA hydrolase and stabilizes ribosomes. In zinc deficiency, the content of ribonucleic acid (RNA) decreases and protein synthesis is hindered.  

(3) Zinc is closely related to carbohydrate conversion, involved in chlorophyll synthesis, and promotes photosynthesis.  

(4) Zinc promotes the synthesis of tryptophan from serine and indole, and indoleacetic acid is converted from tryptophan. Thus, zinc promotes the synthesis of growth hormone and the growth of young leaves, stem ends and roots.

(5) Zinc is related to tryptophan synthase and tryptamine metabolism.  

(6) Zinc is also essential for the stability and functional integrity of cell membranes and cell structures in the root system of crops. Zinc plays a role in protecting the cell membranes on the root surface or in the roots, which can improve the drought resistance of crops.  



To say the least, zinc chloride has a wide range of uses. Fertilization of corn and other crops with zinc chloride products is now being encouraged by authorities in several parts of the world. When zinc chloride is added to irrigation water, it helps to reduce the salt content of the water. This reduces the negative effects of salt on crop soil drainage and helps to eliminate the costly consequences of drainage problems for farmers. Contact COSTALZINC to get the product you want.
