| Abstract: | Continous application of organic manure combined with chemical fertilizers to purple paddy soils enhanced the capability of the root-horizon soil of forming chelated com- pounds of Fe and Mn and increased the content of<0.01mm and<0.001mm water stable aggregates of the soil,thus improving rhizosphere nutrition of N,P and K to the plants. |
