The influence of land use and management measures on the quality of grassland soil

Abstract

Improper conversion of grassland utilization patterns leads to soil quality degradation and increased soil erosion. Analysis of the differences and sensitivities of soil physical, chemical and biological quality indicators under different agricultural management practices, research with the development of Xinjiang YiLi Nalati representing the natural grassland grazing grassland, conventional farming and organic farming fields as the research object. The results showed that the degeneration of soil chemical mass will be much more to see for grazing mode. The most sensitive chemical quality index is soil total nitrogen and organic carbon, especially 0.25-2 mm and 2-8 mm soil organic carbon content. The farmland cultivation mode stimulates the soil microorganism’s ability of absorbing carbon and nitrogen, which goes against the soil carbon and nitrogen’s conservation especially for a long-term fertilizer application in the regular farming mode.
