The study on the dynamics of water-stable aggregates in black soil after reclamation and its relation to soil nutrient status showed that the contents of soil water-stable aggregates decreased significantly at initial reclamation stage, but the declining became small with time. > 0.25 mm water-stable aggregates had a significant correlation with soil organic C, total N, total P and CEC, the correlation coefficients being 0.7625, 0.6794, 0.6084 and 0.8134, respectively, and also had a significant correlation with soil exchangeable Ca, Mg, K, Na. A closer relationship of the aggregates was found with soil organic C and CEC than with other fertility properties, while no evident correlation existed between the aggregates and soil total K, available P, available K and slow-release K. In order to maintain a good aggregate structure of black soil, it is of most importance to concern a proper balance of soil organic C.
