Study on Spatial Distribution of Soil Nutrients and Comprehensive Evaluation of Nutrients in Low Mountain-Hilly Region of Sichuan Province, China

Abstract:

It is generally accepted that to overuse fertilize can led to cause fertilize resource waste, increase agriculture production cost, reducing the quality of agricultural products, and cause agricultural non-point source pollution. Determining soil nutrient distribution is critical to identify sites which are at risk of N, P and K nutrition loading. In order to know the soil nutrition spatial distribution and to determine agricultural rational fertilization, a total of 98 soil samples from the plow layer (0-20 cm) were collected in low mountain-hilly region of Sichuan Province, China. Spatial variability and distribution of soil organic matter (SOM), total N (TN), available nitrogen (AN), available phosphorus (AP) and available potassium (AK) in agricultural soils were studied using geographic information system (GIS) software. And the analytical hierarchy process (AHP) was used to determine the weight of indexes by using quantitative analysis.
