Relationship Between Soil Organic Carbon and Enzyme Activity in Rain-fed Field Under Different Tillage Methods

doi:10.11924/j.issn.1000-6850.casb17040030

Abstract

Abstract: To clarify different tillage on soil organic carbon and soil enzymes activity relationship, this study analyzes?three kinds of tillage methods with trends and correlations: shallow pine (QS), light spin (QX) and subsoiling (SS), and?traditional tillage (CT) as the control.?The result shows: With the soil organic carbon content increase, soil enzyme activity also increases. After using different tillage methods, soil catalase, urease, alkaline phosphatase activity and organic carbon content greater than CT. Compared with CT, different tillage systems also significantly improve yield of oats, and the highest increased rate is 92.18%. There was a significant positive correlation between catalase, invertase activity and urease activity during oat growing season. Therefore, QS, QX and SS are suitable for soil organic carbon content accumulation, yield improvement, and soil enzyme activities increase under drought farmland condition.
