  • 2. SOILS ARE IMPORTANT! - Basis for the provision of food, fibre, fuel and medicinal products. - Stores and releases water, both for plant grow and water supply. - Greatest pool of soil organic carbon. - Regulates carbon, oxygen and plant nutrient cycles (N, P, K, Ca, Mg, etc). - Sustains biological activity, diversity and productivity. - Habitat for seeds dispersion and dissemination of the gene pool. - Central role in buffering, filtering and moderation of the hydrological cycle. - Platform for urban settlement and as material for construction.
