Samples from 17 fields of organic soils (Histosols) were collected on the same day between rows of crops in the summer of 1976 from the environs of Ste. Clothilde, Quebec. Thirty-three properties of the soils were examined for possible correlations. The copper contents of the samples were found to have statistically significant negative correlations with their rates of respiration which were measured as carbon lost as CO2 upon incubation at 21 ± 2 °C. The acid phosphatase enzyme contents in these Histosol samples at each of three different levels of soil biochemical activity were also similarly negatively correlated with their copper concentrations. The above results were confirmed almost without exception by the data obtained by similar analysis of seven samples collected from the same area in the fall of 1976 when the fields were bare. The results supported an earlier suggestion of Mathur and Rayment (1977) that copper application (at a few quintals/ha) be investigated as a means of mitigating the miner...
