Title: Study on Soil Nutrient Status of Woodland in Hilly Region——A case study in Xinguo county of Jiangxi province
Abstract: Soil samples were collected from 84 sample sites in woodland of Xingguo county in Jiangxi province. Sample sites were stratified on the basis of aspect and elevation, soil type,forest type. The strata were compared to determine the influence on woodland soil fertility. The results showed that the soils have small values for pH, total nitrogen, organic matter, total phosphorus and available phosphorus. Soils on southfacing slopes at low elevation contained significantly less total nitrogen and organic matter compared with soils from northfacing slopes at high elevation. The contents of total nitrogen, organic matter and total phosphorus are low, and the content of total potassium is high in Pinus massonniana forest; The contents of total nitrogen and organic matter are high in broadleaved forest; The contents of total nitrogen and organic matte decreased in turn from yellow soil, yellowred soil, brownred soil to red soil; The correlation with aspect and the content of total nitrogen and organic matter is positively significant. The correlation with elevation and total nitrogen, organic matter and total phosphorus is highly significant or significant.
