Agro-Silvo-Pastoralism integrates the knowledge and research of Agronomy, Forest and Extensive Animal Production systems where the soil is the common main factor and looks for application of new technologies on farming systems integrated as a multifunctional way. To improve soil capacity in Mediterranean environments the most efficient process is the improvement of Mediterranean Permanent Pastures and how higher the quantitative and qualitative production of pasture increase the level of Organic Matter in soil and the stocking rate. Also the increase of stock of water in the soil allows the enlargement of the annual cycle in pasture self reseeding plants which means higher biomass production. At some level of soil potential capacity the existence of perennial plants with summer dormancy becomes possible. This means the anticipation of the autumnal start of annual cycle of growth in pasture and decrease of forage supplementation according to the Feeding Scheme of Extensive Animal Production systems. The increase of stocking rates delay the regrowth of shrubs which means the enlargement of Montado Crop Rotation by the increase in variable n (years of pasture). This has positive effect on natural regrowth of tree component because of lower animal pressure and in the balance on vegetal stratus (arboreus, arbustive and herbaceous) with high levels of general biodiversity (animal, vegetal and microbioma). So, increasing the level of bioma in soil which has positive impact on the availability of nutrients and water for plants making easier the sanitary control of vegetal component and increase the general productivity of the whole system. The model of management and multifunctionality can be found in the project of conversion of Mediterranean forest in agro-silvo-pastoral system Montado by Potes et al (20 21).
