Environmental Effects and Relationship Between Soil Organic Matter and Total Nitrogen in Lushan Mountain, China

The content of soil total nitrogen (STN) and soil organic matter (SOM) is important in soil fertility. We analysed four typical soils (red soil, yellow soil, yellow brown soil and brown soil) in Lushan Mountain area to clarify the environmental effects and relationship between STN and SOM. The results showed that there was a significant correlation between soil organic matter and total nitrogen in Lushan soil, which can be established by stepwise regression analysis. SOM and STN may have negative impacts on the growth of plants on the red soil and high STN may lead the underground water into eutrophication. This study is of positive significance for understanding the correlation between soil nutrients, rational development and utilization of soil nutrients in Lushan Mountain.
