Chelated Copper EDTA Fertilizer 14% Cu

Greenway Biotech Chelated Copper EDTA is a water-soluble copper fertilizer with a guaranteed 14% copper, all of it chelated by EDTA. It supplies one micronutrient for two jobs: correcting a copper shortage that a soil or tissue test has confirmed, and providing the copper line in a complete hydroponic or fertigation recipe. Copper is a cofactor in photosynthesis and several plant enzymes and is barely mobile in the plant, so a shortage shows first in young growth.

The label soil rate is 0.8–1.2 oz of product per 1,000 sq ft for vegetable and field crops and 0.8–1.6 oz for tree and vine crops, weighed and watered in once per tested need. For reservoirs, a 1.00 g/L measuring stock delivers 0.14 mg of copper per mL.

Copper accumulates in soil and excess injures plants: apply on a test result, not a symptom, and retest before repeating. Not a fungicide, algaecide, or feed supplement; no foliar rates are given. Packaged in Madera, California, in 1, 2, 5, and 25 lb sizes.
