The pH and content of available N,available P,available K and trace elements of different soil samples from the western regions were determined by acidimeter,flame photometry and atomic absorption spectrophotometer,and the effect of planting oat on content of inorganic elements and trace elements in soil was studied to know the soil composition and nutrient content in western region of Jilin province.The results showed that the distribution of available N,P and K was not uniform in alkaline soils,the content of trace elements had no obvious difference and the pH of some soil samples was up to 9.6.Planting oat in alkaline soils was beneficial to soil acidulation,which indicated that planting oat in alkaline soils can provide a certain help for improvement of alkaline soils in western regions of Jilin province.
