Effects of CaCO3 and Gypsum on leaching of phosphorus and dissolved organic carbon in soil
碳酸钙与石膏对土壤磷及溶解有机碳淋溶的影响

The effects of CaCO_3 and Gypsum on leaching of phosphorus and dissolved organic carbon in soil of sampling(areas) in Southern Australia were studied.The(results) show that CaCO_3 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.
