This is a granular zinc sulfate product with 36% zinc.  Zinc levels should match phosphates levels on a soil test...  If you are deficient phosphate, zinc should be on the low side.  High phosphates necessitates high zinc levels to keep the system balanced.  
The yearly application limit is 35 lbs per acre/year (12.6 lbs actual zinc)
Organic use requires a soil test showing deficient zinc.  Always check with your organic certifier before using any product.
