Abstract:

In order to study the effects of straw mulching and subsoiling on soil organic carbon matter in summer maize field. Four tillage patterns were adopted in Xiping county, Henan province for three years. Four tillage patterns were subsoiling and mulching, subsoiling and no mulching, no tillage and mulching, no tillage and no mulching. Effects of different treatments on the contents of soil organic carbon (SOC), readily oxidizable carbon (ROC), and dissolved organic carbon (DOC) were analyzed. Results showed that the contents of SOC, ROC and DOC under different treatment appeared a declining trend with soil depth. The contents of SOC, ROC and DOC were higher in straw mulching than in no straw mulching, subsoiling and mulching > no tillage and mulching > subsoiling and no mulching > no tillage and no mulching. Below the 10-20cm soil layer, the contents of SOC, ROC and DOC were dropped sharply in the no tillage treatments, subsoiling and mulching > subsoiling and no mulching > no tillage and mulching > no tillage and no mulching. Correlation analysis showed that the contents of ROC and DOC were significant or extremely significant correlation to SOC content, respectively. It showed the ROC and DOC contents in soil were significantly correlated with the SOC content.

Key words: Straw mulching and subsoiling, Soil organic carbon pool, Readily oxidizable carbon, Dissolved organic carbon
