Abstract:
The agricultural soil on the surface of side slope besides the expressway in Anxin was used as the research object，by stratified sampling method for comparative analyzing the soil pH，organic matter，available nitrogen，available phosphorus and available potassium，so as to analyze the fertility of agricultural soils on the road slopes with different soil layers.The results showed that the contents of organic matter，available nitrogen，available phosphorus and available potassium in soils at 0-30 cm were higher than those at 30-60 cm in the slope，and the soil texture was dominated by silt clay loam，supplemented by loamy sand.The content of organic matters in agricultural soils in side slopes of expressway had the most significant influence，followed by available phosphorus，and available potassium had the least influence，pH in soil layers 30-60 cm was larger than that in soil layers 0-30 cm.There were some influence on the fertility of agricultural soils in different soil layers of expressway slope in Anxin area.
