In the last three decades, the cerrado region covering approximately 205 million hectares, has made important contrubutions to the country's crop and livestock production. However, the intensive of this area, particularity for monocropping and pasture development, has give rise to forms of land-use that are neither environmentally nor economically sustainable. Alternative land-use systerms are needed in order to halt and revert declining productivity and losses of soil and water. Among the tecnologies with the potential to accomplish this goal is a combination of crops and pastures in space and time, which happens to be one of our best options. This technology has the potential to increase overall productivity, enhance soil fertility, and contribute to an improvement in the socioeconomic condictions of farmers in the area. Since 1992, the cerrados agricultutal research center (Embrapa Cerrados) and CIAT have worked together with other institutions to develop agropastoral systems based on forage legumes adapted to low high inputs, and to quantify their impact on productivity and soil. Management practices such as land preparation, liming and fertilization, and animal management influence the potential contribution of crops and pastures in integrated crop-pasture production systems. To measure these effects, a long-term experiment was established in a Dark Red Latossol at Embrapa Cerrados in Planaltina (DF), Brazil in 1991. The objective of the experiment was to determine the effect of integration on crop and animal productivity and to identify key soil parameters related to the improvement or degradation of those conditions. The experiment included continuous cropping systems, continuous pasture systems (grass only and grasslegume), and crop-pasture rotation cycles over a period of 4 years. The effects of land-preparation methods on crop productivity and the physical properties of soil were compared between conventional land preparation (with harrow disk plough) and flexible land preparation (with disk plough and moldboard). Fertilization treatments included maintenance fertilization and a corrective fertilization including the use of gypsum on crop and pasture productivity and soil fertility. The experiment was complemented by satelite plots located in several farms in Uberlandia MG. These plots were established in 1992 on sandy and clay soil types, and two production systems (continuous pastures and continuous cropping systems) were used to determine the potential contribution of forage legumes on improving the sustainability of crop-pasture systems. We monitored the changes in animal production and soil fertily of the improved and the unreclaimed systems over time. The results of the crop-livestock case study confirm the synergistic effect on production and soil quality. Soil fertility increased during the cropping cycle, whereas soil aggregation and soil organic matter increased under the pasture phase. Organic matter also appeared to be physically protected in the pastures, especially in sandy soils.
