This is a granular copper sulfate product with 15% copper.  It is released slower in the soil than the water-soluble copper sulfates, making it less prone to leaching and far less harsh on soil microbiology.
The yearly application limit is 53 lbs per acre/year. (8 lbs actual copper)
Organic use requires a soil test showing deficient copper.  Always check with your organic certifier before using any product.
