It was established a silvopastoral multilayer system (SSPm) by natural assisted regeneration (T1) in the area of very dry tropical forest (bms-T) in the municipality of Mercaderes, Department of Cauca, Colombia, which was compared with a conventional system (SC) of Cynodon plectostachyus (K. Schum) Pilg) monoculture (T2). The study area is located at 580 m a. s. l., with precipitation between 600 and 800 mm-1 year-1, and average annual temperature between 27 and 35°C. Some chemical properties were assessed (N, P, K, organic matter [MO], pH) of the soil, floristic diversity, quantity and quality of the forage supply in the treatments, in rainy and dry season, in order to determine the productive and diversity advantages that the silvopastoral systems offer to achieve sustainable livestock production with a constant production of quality edible biomass at all times of the year, and guaranteeing the fertility of the soil. Soil analysis reported higher values in N, K and MO in the SSPm, while in the SC it was obtained higher value of P and pH. The number of plant species in the silvopastoral system was increased by finding 23 vegetable species compared with 4 species found in the conventional system. It was showed how silvopastoral systems favor the production of edible biomass (28.84 Mg MS ha-1 year-1 in SSPm comparative 5.09 Mg MS ha-1 year-1 in SC), finding significant differences between treatments (p<0.05). Thus, it can be concluded that this type of systems represents a good alternative for livestock in this region.
