Soil represents source of nutrients to most of livings organisms. The deficiency or toxicity of some of these nutrients could represent a direct or indirect problem to human health, from nutritional and environmental point of view. The management of soils represents defies for the coming years where population will grow up very fast. The management of soils in a sustainable manner is a main challenge for research, through proper nutrient management and right soil conservation practices. In this senses, further research will be needed to renew soils though a proper management of organic matter to avoid degradation of soils, through erosion and contamination, and production of healthy food to maintain equilibrium to avoid malnutrition by excess or lack of nutrients.
