Carrots (Daucus carota L. cv. Gold Pak 128) were grown in microplots of two organic soils at site A (a peat), and site B (a muck) in the summer of 1984. The soil surface (0 to 20 cm) varied in total Cu from 13 to 1659, and 81 to 1745 μg/g at sites A and B, respectively, mainly due to three levels of applications of CuSO4,.5H2O in 1978. Neither the yield nor the nutrition (P, K, Ca, Hg, Fe, Mn, Zn, Cu, Mo and B) of the carrot crop was significantly adversely affected by the copper applications or the resultant total soil copper levels at both sites A and B. There were decreases in some foliar nutrient levels due to dilution effects attributable to the significant positive correlations between both root and leaf yields and total soil copper at site B. At both sites A and B, the copper additions appeared to have increased the availability of soil Mn, in accord with earlier evidence.
