Evolution of Paddy Soil Fertility in Tonglu County in the Past 30 Years

NI Zhongying;LIU Yonghong;SHI Yijun;TANG Bin;Agricultural Technology Promotion Center of Tonglu County;  
In order to understand the status and evolution trend of fertility of paddy soils in Tonglu county, Zhejiang province, historical changes in soil p H, organic matter, available P, available K of the cultivated layer were analyzed over the past 30 years by comparing data obtained from the current soil quality investigation of cultivated lands and the second national soil survey. The results showed that those soil fertility indexes of cultivated layer of paddy soils in the county changed greatly in the past 30 years, but the direction and degree of the change varied with nutrient types and zones. The soils were slightly acidified, and averaged pH declined0.07 p H unit. The soil cation exchange capacity of paddy soils in the county was at low level. The organic matter of the soils was significant decreased by 17.32%. The decrease proportion of soil organic matter in Fenshui town was 24.17%, and was the largest in the whole county. The available phosphorus and potassium were significant improved by 173.75% and 63.05%, respectively. The soil available P has emerged accumulation phenomenon in some area. The most obvious accumulation appeared in Tongjun town, and it was increased by 316.24%. The available K was also remarkable improved, but it was still at a moderate level, and Tongjun town was increased by 112.62%. The changes in soil fertility of paddy field in the county were relate to the changes in fertilization structure and cropping system in the past 30 years.
