Role of Copper in Tomato Production

Copper is involved with carbohydrate and nitrogen metabolism. It is also linked to chlorophyll performance.

General guidelines for Copper application

Reports of copper deficiencies are rare in greenhouses. In field cultivation, they are most likely on sandy or organic soils. Basal applications of copper sulfate to deficient soils increase yield and quality of tomato crops.
