SATDAS’ good management of land ensures that land does not become deficient of mineral elements or toxic to plants, and that right mineral elements enter the food chain. It implies that SATDAS ensures that soil become resilient, (i.e. after land being imperiled to the stresses involved in crop production, it obligation for the land to have the capability to return to its prior state, or an improved state). SATDAS land management is critical, both directly and indirectly, to environmental sustainability, agricultural productivity, and human health. Through research, SATDAS land management evades further degradation of land, through soil erosion or soil contamination, and to produce adequate safe and nutritious food for healthy diets.
