“…Average soil chemical analyses in the SPS and OP were, respectively, as follows: pH (water), 4.7 and 4.7; phosphorus (Mehlich-1), 3.7 and 1.9 mg/dm 3 ; potassium, 50.6 and 49.5 mg/dm 3 ; calcium, 0.9 and 0.7 cmolc/dm 3 ; magnesium, 0.4 and 0.3 cmolc/dm 3 ; aluminium, 0.9 and 0.7 cmolc/dm 3 ; H + Al, 6.0 and 5.4 cmolc/dm 3 ; and organic matter, 3.8 and 3.8 dag/kg. The experimental area, where this study was carried out, has been used in multidisciplinary studies since its establishment in November 1997 (Müller, Fernandes, de Castro, Paciullo, & Alves, 2010;Paciullo et al, 2010;Xavier et al, 2014). The SPS is structured in 30-m-wide strips with the tropical perennial grass Brachiaria decumbens syn.…”

Silvopastoral system (SPS) has been suggested to ensure sustainability in animal production systems in tropical ecosystems. The objective of this study was to evaluate the productive and nutritive value traits of Brachiaria decumbens and performance of dairy heifers in SPS and open pasture (OP) during the summer and autumn of two consecutive years in the SPS and OP (17th and 18th years after establishment). Experimental design was a randomized complete block with two treatments (SPS and OP) and three replications in subdivided plots with repeated measures in time. There was reduction in the tiller population density, total and green forage mass, and total and green forage bulk density in the SPS when compared to the OP in the summer. In the autumn, no difference was observed between the systems. Shading in SPS increased crude protein content of the grass pasture by 25% and 33% when compared to the OP during the first and second experimental years, respectively, and reduced neutral detergent fibre content. However, it did not change acid detergent fibre or lignin content. OP provided higher stocking rate and weight gain per area than the SPS. Average daily gain was higher in the OP in the second experimental year. Severe shading conditions should be avoided, because in the long‐term they may threaten the persistence and sustainability of pasture in the SPS. It is recommended to plant a low density of trees or implement management strategies of the tree component by either thinning or pruning over the years after planting.

“…All systems were important in carbon sequestration and had environmental benefits such as soil fertility and water quality improvement and erosion reduction 18,38–40 . The estimated MAI-AGB found was higher than the 1.43 t ha −1 yr −1 in a silvopastoral system with 105 trees per hectare (eucalypt and acacia) in Minas Gerais, Brazil 41 . The MAI-AGB of 7.67 t ha −1 yr −1 of an agrosilvopastoral system with eucalyptus spaced 10 × 4 m and rice in Paracatu, Minas Gerais, Brazil 42 was similar to that observed in the system 2 of this research.…”

Agrosilvopastoral and silvopastoral systems can increase carbon sequestration, offset greenhouse gas (GHG) emissions and reduce the carbon footprint generated by animal production. The objective of this study was to estimate GHG emissions, the tree and grass aboveground biomass production and carbon storage in different agrosilvopastoral and silvopastoral systems in southeastern Brazil. The number of trees required to offset these emissions were also estimated. The GHG emissions were calculated based on pre-farm (e.g. agrochemical production, storage, and transportation), and on-farm activities (e.g. fertilization and machinery operation). Aboveground tree grass biomass and carbon storage in all systems was estimated with allometric equations. GHG emissions from the agroforestry systems ranged from 2.81 to 7.98 t CO2e ha−1. Carbon storage in the aboveground trees and grass biomass were 54.6, 11.4, 25.7 and 5.9 t C ha−1, and 3.3, 3.6, 3.8 and 3.3 t C ha−1 for systems 1, 2, 3 and 4, respectively. The number of trees necessary to offset the emissions ranged from 17 to 44 trees ha−1, which was lower than the total planted in the systems. Agroforestry systems sequester CO2 from the atmosphere and can help the GHG emission-reduction policy of the Brazilian government.
