Distribution of Available S in the Soil Environment of Yunnan Plateau

Abstract:

S element is essential nutrient element of the crop and has spatial variability in soil. It is the base of managing soil S nutrition and reasonable fertilization to understand spatial variability of soil S element fully. Distribution of available S for Baiyao base was studied in this paper. Results show that the available S content of Baiyao base soil was 18.39 mg/kg on average, but the variation range was larger, and 80.84% SAI value of the soil samples were lower than 14, so the base soil had a greater risk of S. The higher available S content were mainly distributed in the middle, east and south areas of Baiyao base, but there were wide areas with lower S content in Baiyao base. In addition, OM had low linear correlation with available S. Nutrient division management was recommended to improve the reasonable application of S.
