The soil nutrient were tested and analyzed by collecting 566 samples of paddy soils in Quangang district.The results showed that the average contents of organic matter was 23.08 g/kg,83.57% of the samples were in a middle and low level;the alkali-hydrolyzable nitrogen content of paddy soil was 115.11 mg/kg,95.05% of the samples were in a middle and absent level;the available phosphorous content was 14.82 mg/kg,54.06% of the samples were at absent level;the available potassium content was 61.73 mg/kg,81.27% of the samples were at absent level;the value of pH was in a low level,81.62% of the samples were at acidic to strong acid level;each type of the soil nutrient content was slightly different.At present,paddy soil fertility of Quangang distcict overall was low,medium low level of organic matter,low nitrogen,low phospho rus and low potassium level.
