土壤有机质是土壤的基础物质,是土壤肥力高低的重要指标。因此,土壤每年消耗的有机质,需要施用有机肥料加以补充,以解决耕作土壤中有机质转化和其平衡问题。各种有机物料由于成份不相同,它们在同—土壤中的腐解残留率亦不同。为了能做到按预定的土壤有机质水平为目
Soil organic matter is the basic material of the soil, is an important indicator of soil fertility. Therefore, the annual organic matter consumed by the soil needs to be supplemented with organic fertilizers to solve the problem of organic matter transformation and its balance in cultivated soils. Due to the different composition of various organic materials, they are in the same - soil decomposing residue rate is also different. In order to be able to do so according to the predetermined level of soil organic matter for the purpose
