Copper Sulfate

25% copper

Copper sulfate can be used in dry fertilizer blends when the soil copper levels are lower than 2-3 ppm. Normal rates are 2-5 lbs. per acre although higher application rates may occasionally be beneficial. Do not use in sheep pastures. Always mix a good carbon source (humus compost or humates) with copper sulfate before applying, or copper oxidation in soil can occur. If all trace minerals are low, consider using Micro Hume instead.

Disclaimer: NOP approved with restrictions on copper.
