碳酸钙与石膏对土壤磷及溶解有机碳淋溶的影响

Effects of CaCO₃ and Gypsum on leaching of phosphorus and dissolved organic carbon in soil

摘要: 研究碳酸钙与石膏对南澳大利亚典型土壤P和溶解有机碳淋溶的影响结果表明，碳酸钙可同时降低土壤P和溶解有机碳的淋溶，而石膏可降低土壤P淋溶和增加溶解有机碳的淋溶。

Abstract: The effects of CaCO₃ and Gypsum on leaching of phosphorus and dissolved organic carbon in soil of sampling areas in Southern Australia were studied. The results show that CaCO₃ can reduce the leaching of both P and dissolved organic carbon; Gypsum can also reduce the leaching of P, however, it dramatically increases the leaching of dissolved organic carbon.
