SATDAS good management of land ensures that land do not become deficient of mineral elements or toxic to plants, and that right mineral elements enter the food chain. It implies that SATDAS will ensure 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 will be able to evade further degradation of land, through soil erosion or soil contamination, and to produce adequate safe and nutritious food for healthy diets.
