1976年夏天,在同一天,从Ste附近的17块有机土壤(组织土)中收集了作物行之间的样品。魁北克的克洛西德。土壤的33个属性进行了检查可能的相关性。发现样品的铜含量与其呼吸速率具有统计学显著的负相关性,呼吸速率是在21 ± 2 ° C下孵育时以CO2形式损失的碳。  酸性磷酸酶含量在这些组织土样品在每三个不同水平的土壤生化活性也同样呈负相关,其铜浓度。上述结果几乎无一例外地得到了1976年秋季从同一地区采集的7个样品的类似分析所获得的数据的证实,当时田地是光秃秃的。这些结果支持了Mathur和Rayment(1977年)的早期建议,即应研究施用铜(几公担/公顷)作为减轻采矿业的一种手段。
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...
