Soil Organic Matter; Soil; Arable Land; Agricultural.Abstract
Soil organic matter (SOM) in China's arable land is a critical foundation for maintaining agricultural productivity and ecosystem health. However, in recent years, the content of SOM has shown a declining trend due to unsustainable agricultural practices, excessive use of chemical fertilizers, and land degradation. This decline has adversely affected soil fertility, water retention capacity, biodiversity, and carbon sequestration. Although certain regions have seen improvements through the application of organic fertilizers, straw return, and conservation tillage, the overall SOM levels remain low. Therefore, there is an urgent need to develop comprehensive management strategies to increase SOM content, promote sustainable agricultural development, and protect the ecological environment.
