Title: A Study on Spatial Variability of Soil Nutrients Based on GIS
Abstract:The soil nutrient status and their spatial variability in 0-20 cm soil layer of the thirteenth village of Gongpeng town, Yushu city,Jilin province were studied by application of geographic information...The soil nutrient status and their spatial variability in 0-20 cm soil layer of the thirteenth village of Gongpeng town, Yushu city,Jilin province were studied by application of geographic information system (GIS) and geostatistics knowledge. After the 239 soil samples were tested, the results showed that state of soil is better. It is also showed that there existed spatial variability of soil nutrients. The maps based on the spatial variability of soil OM ,available P and water content were designed and the spatial variability rules were designed by the application of GIS technology. The conclusion that different spatial variability of available nutrients was deeply affected by their mobility was got easily. The results would become a means of guiding farmer fertilization and be valuable in precision agriculture.Read More
