Abstract: Effect of high ridge and low gully, shallow root planting, integrated disposal on soil fertility in waterlloged Jiangnan alder forestry were studied. The results showed that integrated treatment had the most significant effect on soil fertility, and had the highest amount of agglomeration degree, >0.25 mm water stable aggregate content, total porosity, non-capillary porosity, and soil available nutrient content. Also it had the lowest amount of dispersion coefficient, soil bulk density and soil structure damage rate, and had the highest stand volume and the optimal comprehensive performance.
