| Abstract: |
| Taking Wuzhong State Agro-Hi-Tech Demonstration Zone as an example, this paper explained the large\|scale soil nutrients mapping based on Quickbird image, Arcgis 9 desktop and DGPS, as well as necessary field and lab works.The approach followed DGPS-based field 100 m grid soil sampling, ASI soil testing, Quickbird\|based field surveying for farmland and settlement boundary, and soil nutrients database, spatial interpolation and soil mapping.This 3S-based soil nutrients mapping approach, integrated into ArcGis geodatabase framework, was efficient and accurate.It facilitated greatly single and comprehensive nutrient assessment and fertilization recommendation. |
