Soil is the sustaining media to most of livings organisms, being a source of most nutrients. The correct management of soil marks the limits between deficiency and toxicity of some of these nutrients. Thus, soil management could represent a direct or indirect problem from nutritional and environmental point of view to plants, animals, and directly or indirectly to human health.

Because of the intensification of food production, the management of soils becomes an important defy for the coming years because of the increase of world population. In this new basis, the management of soils in a sustainable manner is a challenge for research, through proper nutrient management and right soil conservation practices. In this sense, further research will be needed to avoid further degradation of soils, through erosion and contamination, and to product food for healthy diets, in quantity and quality.
