摘      要：Conservation management practices e including agroforestry,cover cropping,no-till,reduced tillage,and residue return e have been applied for decades to control surface runoff and soil erosion,yet results have not been integrated and evaluated across cropping *** this study we collected data comparing agricultural production with and without conservation management *** used a bootstrap resampling analysis to explore interactions between practice type,soil texture,surface runoff,and soil *** then used a correlation analysis to relate changes in surface runoff and soil erosion to 13 other soil health and agronomic indicators,including soil organic carbon,soil aggregation,infil-tration,porosity,subsurface leaching,and cash crop *** all conservation management practices,surface runoff and erosion had respective mean decreases of 67%and 80%compared with *** of cover cropping provided the largest decreases in erosion and surface runoff,thus emphasizing the importance of maintaining continuous vegetative cover on ***-and medium-textured soils had greater decreases in both erosion and runoff than fine-textured *** in surface runoff and soil erosion under conservation management were highly correlated with soil organic carbon,aggregation,porosity,infiltration,leaching,and yield,showing that conservation practices help drive important in-teractions between these different facets of soil *** study offers the first large-scale comparison of how different conservation agriculture practices reduce surface runoff and soil erosion,and at the same time provides new insight into how these interactions influence the improvement or loss of soil health。
