Analysis of the Effects of Different Tillage Methods on Soil Water Holding Characteristics and Organic Carbon Storage in Farmland

Abstract

Analyze the impact of tillage on soil carbon storage, define scientific farming methods in Chengdu Plain, China, and provide the basis for regional optimization of farming models and soil improvement. Based on 4 location experiments, two tillage treatments, conventional tillage (CT) and no tillage (NT), were selected to analyze the difference of the impact of tillage on organic carbon. Due to different crop types and soil properties, there are regional differences in the impact of no tillage on soil organic carbon storage, which can significantly improve the surface soil organic carbon storage in various regions. In general, no tillage conservation tillage technology is an effective way to improve surface organic carbon storage.
