Effect of Fertilizer Application on Rice Yield and Physical-chemical Properties of Paddy Soils

Abstract

Abstract: A field experiment was made for examining the effect of different fertilizers on the balance of nutrients and crop yields. It was showed that N and p were surplus in the treatment of pig manure application, but deficient in that of chemical fertilizer application, and K was deficient in the both. Crop yield was increased by using chemical fertilizer and orgaic manure. 4 years field experiment revealed that organic manure could increase the storage of natrients in soils and improve soil fertility and crop yield.

Key words: Soil humidity, Vegetation coverage, Wind erosion
