A high-analysis source of Zinc (Zn) and Sulfur (S) for optimal leaf sizing, water absorption and strong production

Zinc is a very important yield factor in that it is chiefly responsible for leaf sizing. With the leaf being the plant's primary solar panel, the overall size (surface area) of the leaf will directly govern the amount of sunlight that can be captured by the plant to feed photosynthesis. Photosynthesis is responsible for 90% of all plant production so improving photosynthesis is improving plant production. 

In addition, when you supply adequate zinc levels to your crop, water absorption is enhanced as are flower and fruit development, as well.  Because water is required for all nutrient uptake and nutrient translocation within the plant, improving water absorption is key in achieving top production.

How to Apply

Zinc Sulfate 35.5% Monohydrate Maxi-granular is a dry amendment that can be applied directly to the soil. It can be mixed with other dry amendments such as humates and other dry fertilizers. The rate applied depends on the results of soil analysis.

Zinc Sulfate 35.5% can also be dissolved and added to foliar solutions. The application can be as often as every other week, depending on the results of tissue analysis.

In direct relation to Phosphorus, zinc should generally maintain a P: Zn ratio of 10:1. 

* A jar test should be conducted when mixing Zinc Sulphate with any other product to ensure compatibility.
