A Study on Characteristics and Enhancement Mechanism of Organic Carbon in Farmland Soils in Ningxia
Organic carbon is the core of soil quality and fertility,and directly affects the change process of soil physical,chemical and biological properties.Improving soil organic carbon pool is an important way to maintain sustainable agricultural development.Based on the relevant investigation and research,the content characteristics of soil organic carbon and its humus carbon components in Ningxia farmland and the correlation between them and soil nutrients are analyzed,the mechanism issues that need to be revealed in the study of farmland organic carbon enhancement in Ningxia are expounded,and the research direction of farmland organic carbon enhancement mechanism is proposed,aiming to provide theoretical basis for the continuous optimization of farmland organic carbon enhancement technology in Ningxia.
