“…Thereafter, a competition may have already occurred between species and consequently decreased soil coverage. The advantage of vegetation cover by Brachiaria has also been found in other research papers (Horvath Neto et al, 2012;Silva et al, 2014a;Silva et al, 2015;Paula et al, 2017). The onset of the rainy season in October contributed to increases in land cover compared to July.…”

“…Therefore, Brachiaria have better absorbed the fertilizer nutrients during regrowth, resulting in higher dry matter yield in the density of 8 viable pure seeds m -2 relative to the broadcast system. Therefore, the results demonstrate the potential of the forage biomass production and adaptation to cultivation in Cerrado soils (Paula et al, 2017).…”

“…The search for sustainability in Brazilian agricultural systems has led to diversification and integration of activities on rural property (Bonaudo et al, 2014;Lemaire et al, 2014;Paula et al, 2017). In this context, intercropping of annual crops with tropical forage grasses, being used in crop-livestock integration systems has been increasingly adopted by farmers in the Cerrado region (Loss et al, 2012;Oliveira et al, 2015;Paula et al, 2017). The system in question allows the cultivation of crops for grain and straw production, aiming to cover the soil or the formation of grazing pastures (Moraes et al, 2014).…”

Sorghum intercropping with Brachiaria has the potential to improve grain yield and dry matter in the Cerrado region, but there are no studies on the ideal density of Brachiaria seeds for adoption in intercropping when the system is deployed at the beginning of the rainy season. Thus, the objective of this study was to determine the intercropping of sorghum with Brachiaria ruziziensis that may provide higher yield of grain sorghum and dry mass of both crops. We also evaluated the performance of soybeans in succession after intercropping. The test was conducted in 2013/14 and 2014/15 in tropical climate region with wet and dry seasons. The experimental design followed a randomized complete block in a factor 3 x 5 + 1 + 5, corresponding to three intercropping Brachiaria ruziziensis seeding systems (row, inter-row and broadcast sowing) associated with five densities of Brachiaria (2, 4, 6, 8 and 10 pure viable seeds m -2) plus the additional treatments related to monocultures of the grain sorghum and the five densities of the Brachiaria. The Brachiaria ruziziensis association with sorghum cultivation proved to be a promising technique for improving grain yield and dry matter at different times of the year without affecting the development and yield of the soybean crop culture. The best results were achieved with planting of Brachiaria ruziziensis in the line at the sowing density of 8 viable pure m -2 seeds and the inter-row sowing density of 6 viable pure m -2 seeds.

“…It is a country that has the necessary resources to increase food production and contribute to the world's food supply [3,4]. The use of this technology has made it possible to expand the frontier to previously marginalized regions, especially the Cerrado region, which has contributed greatly to increasing the country's grain, livestock and agro-energy production [5,6].…”

Soybean is one of the most widely grown crops in the world and technologies are increasingly needed to increase productivity without impacting environmental degradation. In this context, the aim was to evaluate the action of forage plants of the genus Brachiaria sp. in crop–livestock integration on physical soil, agronomic and environmental aspects of soybean cultivation. The experiment was conducted in a subdivided plot design with seven integrated systems corresponding to the previous cultivation of Paiaguas palisadegrass, Xaraes palisadegrass and Ruziziensis grass in monocropping and intercropped with maize, as well as maize in monocropping. In the subplots, two grass management systems were evaluated: free growth and a grazing simulation cut. The bulk density and least limiting water range were assessed using soil samples and, after the pastures were desiccated when the soybean crop was planted, straw decomposition and plantability. A soil physics diagnosis by the bulk density and least limiting water range showed that the Paiaguas palisadegrass and Xaraes palisadegrass improved the soil environment due to biological soil loosening. The remaining mulch biomass did not affect soybean sowing and the adoption of Brachiaria sp. grass in the off-season, in addition to contributing to the provision of environmental services, and did not compromise grain productivity in succession.

“…The use of conservationist systems of soil management associated with previous crops (soil cover plants) to commercial crops may contribute to higher productivity [6]. Thus, in the conditions practiced by tropical agriculture, it can be considered that soil management aiming at reducing compaction, as a viable alternative, resulting from the absence of soil rotation and increased biological activity [7].…”

Conservation systems for less soil movement and when associated with previous crops may reduce the effects of soil compaction. The objective of this work was to evaluate soil mechanical resistance penetration (MRP) in different cropping systems associated with previous corn crop after fifteen years. The experimental design was composed of experimental strips with subdivided plots, combining three soils management systems: CC- conventional cultivation, MC- minimum cultivation and NT- no-tillage, and four species of crops antecedent to maize for the production of commercial ears of green corn. In the determination of soil MRP, the electronic penetrometer (FALKER model SoloTrack PLG 5200) was used, with readings up to a depth of 400 mm. The results showed that there was a significant effect on the MRP values of the soil when submitted to the different cropping systems and previous crops at the end of fifteen years. The lowest MRP values were located in the superficial layers in the CC and MC. The NT cultivar system showed higher MRP values, at depth 0-100 mm. At conditions of tableland, after fifteen years, it was observed that the NT system provides better corn productivity levels combined with lower MRP values along the profile.
