Over 40% of the estimated 130 X 10 (expoente) 8 cattle population in Brazil is found in the "Cerrados" (savannas), a region which covers more than 200 million hectares. Livestock production levels per animal and per area are low and have remained stagnant for several decades. Forages are low in protein, digestible energy and minerals, particularly phosphorus, especially during the long dry season. It is estimated that by 1990 over 40 million hectares had been planted to pasture and over 12 million hectares had been planted to annual crops. More than 150 million tons of crop residues and by-products, mainly from corn, soybeans and sugarcane are potentially available to help solve the dry season feed shortages in integrated crop livestock production systems. Numerous forage grasses and legumes adapted to the cerrado ecosystem have been released. Recent research on legume-based pastures has demonstrated their large potential. Effectiveness of cheaper alternative phosphorus sources has been demonstrated. The integration of livestock and annual crop production systems is new but shows promise of potential synergism with important advantages for both livestock and crops. One of the major goals in developing efficient and sustainable production systems for the cerrados to meet the growing demand for food is to reduce pressure on the rainforests of the Amazon basin. |

Glyphosate-Resistant Crops (GR crops) have caused considerable changes in weed management worldwide. In Brazil, GR cultivars of soybean and corn were officially introduced in the 2005/06 and 2011/12 crops, respectively. This technology has radically changed the weed management system, having an enormous impact on national agriculture. The objective of this review was to analyze the general aspects that led to the adoption of this technology in Brazil and present its future consequences and challenges. The adoption of GR soybean and corn was swift and comprehensive. Ten years after its introduction, GR soybean and corn are grown in most areas with these crops in Brazil. This success can be attributed to the reduction of costs, the broad spectrum of control provided by glyphosate, the solution for effective management resistance to ALS and ACCase inhibitors, the excellent managing of weeds that are difficult to control, the reduction of crop injury and carryover problems. However, the exclusive and consecutive use of glyphosate alone resulted in intense selection pressure for resistant weeds to this herbicide, which has become one of the most prominent challenges with these crops. Therefore, the future sustainability of GR soybean and corn will not be possible without the combination with other technologies, within integrated weed management. |
