An experiment of agro-pastoral systems is being conducted by the National Beef Research Center (CNPGC), in Campo Grande, MS, Brazil, since 1993/94, in the region known as Cerrados (typical Savannas). The hypothesis tested is that agro-pastoral systems could improve crop and animal production, being more profitable and sustainable than continuos and tradicional systems. Five farming systems are being tested: two traditional (continuous soybean annual cropping and continuous pastures cropping) and three agro-pastoral systems (two combinations of four by four years of rotational crop-pasture systems and one by three years of crop-pasture rotation). Sub-treatments of different planing systems (traditional: disking only; dynamic and conservationist: disk plowing-moldboard plowing-subsoiling; and direct planting: no-tillage) and differen tropical forages (Brachiaria decumbens, B.Brizantha and Panicum maximum) are also studied. Continuous pasture cropping of B. decumbens has three sub-treatments: with and without maintenance fertilizar and maintenance fertilezer plus intercropped pasture legume: Syloshantes spp. Two additional plots were included as treatment comparisons and to check for environmental impacts: an area of degraded pasture and one of natural vegetation. After nine years of cropping, overall average soybean yields are ranking over 2500 kg/ha. Grain yield of soybean in continuous notillage system was not different to continuous tillage systems.Soybean production in agro-pastoral systems differed between treatments, dependingupon residual soil fertility, climatic constraints (drought spells) and competition by pasture regrow. Animal production in continuos pasture cropping measured as liveweight gain/ha (LWG) are declining along the years in the subtreatment without fertilizer maintenance. Agropastoral systems, in the other hand, have shown promising results of LWG, either in the one by three or inthe four by four cropping combination. Soil fertility under continuous annual crops increased substantially. In crop/pasture rotation, soil fertility with grain crops, but decreased rapidly in subsequentgrazing systems with no fertilizer maintenance.
