Grain, meat, and milk production systems in the Brazilian savannas, also known as the Cerrados, are currently experiencing increasing economic and environmental problems. These problems could have detrimental effects on the natural resource base and on the sustainability of agriculture in the region over the long term if alternative systems are not developed. One option that would intensify agricultural production while minimizing negative impacts on soil and water involves the integration of cropping and livestock systems in time and space (agropastoralism). Since 1992, CIAT and EMBRAPA-CPAC have worked together with other institutions to develop agropastoral systems that are based on forage legumes adapted to low and high inputs, and to quantify their impact on productivity and on soil. Most of these activities were carried out on farms in the Uberlandia region of the State of Minas Gerais in central Brazil. Experiments with the legumes Stylosanthes guianensis cv. Mineirao and Arachis pintoi BRA-031143 in crop/pasture systems showed that while the first legume was effective in low-input systems, the latter was better adapted to high-input systems, crop rotation (ley farming) or as a permanent ground cover in direct sowing. However, chemical or mechanical methods were needed to control A. pintoi's competitivenss with crops. The results of a crop/livestock case study confirmed 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 underwent a process of physical protection under pastures, especially in sandy soils. Subsequent surveys showed that crop/livestock integration is gaining aceptance amongst grain producers.
