Notes:
Summary The amount of copper extracted from soils by EDTA was found to increase with the temperature of extraction. Under controlled conditions of extraction, the amount of applied copper extracted from soils by EDTA decreased during incubation of soils under both moist and dry conditions. The recovery of applied copper by EDTA appeared to be related to the amounts of manganese and iron oxides in the soil. On the basis of comparisons with calcium chloride-extractable copper and isotopically-exchangeable copper it is suggested that EDTA extraction could over-estimate the availability of soil copper to plants.
