We also want to establish the limiting factors of soil productivity for different crops in different Agricultural Improvement Stations in Taiwan based on the soil fertility capability classification (SFCC) system. How to exclude the limiting factors of soil productivity from the data bases? The third item is to sample the representative soil pedons in the high variation area to reduce the spatial variability of different soil series in one soil management groups. The sampling proposal is to sample 2 soil management groups, 5 representative soil series and 10 pedons in one year.土壤管理組土壤品質土壤肥力限制因子永續農業soil management groupsoil qualitylimiting factor of soil fertilitysustainable agriculture
