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.

Research shows that zincdeficient soils result in reduced grain yields partly

due to poor pollen frtility which is governed by zinc.

Zinc deficiency also causes stunted growth and a decrease in leaf size or “little

leaf”. As the leaf is the solar panel for the plant, it enables the most critical of plant

functions that govern overall production- photosynthesis.

Since zinc determines leaf size, the availability of zinc to the growing crop is of great

importance to improving plant performance and yield through enhanced photosynthesis.

application rates

Rates of application will vary based mineral content of soil and tissue and should be

determined using results of soil and tissue analysis. In general,zinc can be applied at

between 2-6 lbs/acre. Can be dissolved in water for spray application. Consult with your

advisor for liquid application options.
