Abstract

Cauliflower (Brassica oleracea Botrytis cv. Snow Crown) was grown in field microplots of an organic soil containing residual fertilizer Cu varying from 81 to 1063 ppm (w/w) as a result of three levels of Cu applications made in the previous two seasons. The variation in soil‐Cu was found to have no significant influence on the yield, nutrition or copper status of the crop.
