A NEW STRATEGIC APPROACH USED FOR THE REGENERATION OF SOIL FERTILITY, IN ORDER TO IMPROVE THE PRODUCTIVITY IN ECOLOGICAL SYSTEMS.

The constant pressure to increase food, fiber, and fuel production in order to meet the increasing global demand and prevent malnutrition has put significant pressure on soil resources. Minimal attention to soil protection and conservation, inadequately aggressive management, as well as climate change have resulted in abandoned, degraded, and the expansion of agricultural marginal areas with major agricultural limitations. Agricultural production on degrading land necessitates increasing amounts of chemicals such as fertilizers and pesticides with a negative longterm effect. In recent years, many activities have been proposed to improve soil characteristics starting with the change of cultivation methods, grazing, mulching, composting, soil conservation, green manuring, soil remineralization, however no clear strategies are known to integrate all these measures in a unitary way. which helps farmers to restore degraded soils, while obtaining high yields in organic farming. To reverse these trends, fundamental adjustments in productive systems are required, including the implementation of sustainable natural resource management. Our study proposes a strategy that successfully integrates several soil regeneration techniques, as well as design new planning that allow farmers to benefit from the services offered by agroecosystems.
