“…These results are in accord with those of Lenka et al (2012) from central India, who also reported a higher WSA in soils under forest based pasture. Tree roots can penetrate deeper into the soil compared to those of annual crops (Mekonnen et al, 1997) and they release enzymes, which accentuate the aggregation process (Paudels et al, 2012).…”

SUMMARYSoil physical quality is an important factor for the sustainability of agricultural systems. Thus, the aim of this study was to evaluate soil physical properties and soil organic carbon in a Typic Acrudox under an integrated crop-livestock-forest system. The experiment was carried out in Mato Grosso do Sul, Brazil. Treatments consisted of seven systems: integrated crop-livestock-forest, with 357 trees ha -1 and pasture height of 30 cm ); integrated crop-livestock-forest with 357 trees ha -1 and pasture height of 45 cm ); integrated crop-livestockforest with 227 trees ha -1 and pasture height of 30 cm ); integrated croplivestock-forest with 227 trees ha -1 and pasture height of 45 cm ); integrated crop-livestock with pasture height of 30 cm (CL 30 ); integrated croplivestock with pasture height of 45 cm (CL 45 ) and native vegetation (NV). Soil properties were evaluated for the depths of 0-10 and 10-20 cm. All grazing treatments increased bulk density (ρ ρ ρ ρ ρ b ) and penetration resistance (PR), and decreased total porosity (ƒ t ) and macroporosity (ƒ ma ), compared to NV. The values of ρ ρ ρ ρ ρ b (1.18-1.47 Mg m -3 ), ƒ ma (0.14-0.17 m 3 m -3 ) and PR (0.62-0.81 MPa) at the 0-10 cm depth were not restrictive to plant growth. The change in land use from NV to CL or CLF decreased soil organic carbon (SOC) and the soil organic carbon pool (SOC pool ). All grazing treatments had a similar SOC pool at the 0-10 cm depth and were lower than that for NV (17.58 Mg ha -1 ).Index terms: agroforestry, soil organic carbon, multivariate analysis. A qualidade física do solo é um importante fator para a sustentabilidade dos sistemas agrícolas. O objetivo desta pesquisa foi avaliar as propriedades físicas do solo e o carbono orgânico em um Latossolo Vermelho distrófico, sob sistema de integração lavoura-pecuária-floresta. O experimento foi conduzido no Mato Grosso do Sul, Brasil. Os tratamentos consistiram de sete sistemas: integração lavoura-pecuária-floresta, com 357 árvores ha -1 e altura de pastejo de 30 cm ); integração lavoura-pecuária-floresta, com 357 árvores ha -1 e altura do pastejo de 45 cm (CLF 357-45 ); integração lavoura-pecuária-floresta, com 227 árvores ha -1 e altura do pastejo de 30 cm ); integração lavoura-pecuária-floresta, com 227 árvores ha -1 e altura do pastejo de 45 cm ); integração lavourapecuária, com a altura do pastejo de 30 cm (CL 30 ); integração lavoura-pecuária, com a altura do pastejo de 45 cm (CL 45 ); e vegetação nativa (NV). As propriedades do solo foram avaliadas nas profundidades de 0-10 e 10-20 cm. Todos os tratamentos com pastagem aumentaram a densidade do solo (ρ b ) e resistência à penetração (RP) e diminuíram a porosidade total (ƒ t ) e macroporosidade (ƒ ma ), em comparação com a NV. Os valores de ρ b (1,18-1,47 Mg m -3 ), ƒ ma (0,14-0,17 m 3 m -3 ) e PR (0,62-0,81 MPa) na profundidade de 0-10 cm não foram restritivos ao crescimento de plantas. A mudança de uso do solo a partir NV para CL ou CLF diminuiu o carbono orgânico (SOC) e o estoque de carbono orgânico (SOC...

“…It means that in multicropping systems, such as agroforestry system, the presence of pioneer tree species and the lesser removal of plant residues contribute significantly to mitigate the loss of C and decrease greenhouse gas emissions. Also, agroforestry systems have higher potential to build up and sequester C in soils because of the increased rates of organic matter addition and retention (Lenka et al, 2012).…”

The aim of this study was to assess the carbon pools of a tropical soil where the native forest was replaced with different pasture systems. We studied five pasture production systems, including four monoculture systems with forage grasses such as Andropogon, Brachiaria, Panicum, and Cynodon, and an agroforestry system as well as a native vegetation plot. Greater availability of fulvic acid was detected in the agroforestry system as compared with that in the other systems. Higher lability of C was detected in the Andropogon system during the dry and rainy seasons and during the dry season in Cynodon. During the dry season, all pastures systems showed deficits in the net removal of atmospheric CO2. The structure and practices of the agroforestry system enables more carbon to be sequestered in the soil as compared with the monoculture pasture, suggesting that it is an important practice to mitigate climatic change and to improve soil quality.

“…Hence, roots may supply more stable C to the soil as observed by Makumba et al (2007) studying the effect of agroforestry practice on C sequestration and CO2-C efflux in a gliricidia-maize intercropping system. Lenka et al (2012) and Pinho et al (2012) have suggested that AFSs, especially with the insertion of trees, have higher potential to build up and sequester C in soils because of the increased rates of organic matter addition and retention. However, according to Derpsch (2008), clear increases in soil organic matter only appear 5-10 years after the adoption, as verified in the AFS13 system.…”

RESUMO -This study aimed at quantifying total organic carbon stocks and its pools in Acrisol under agroforestry systems with six (AFS6) and thirteen years old (AFS13), slash-and-burn agriculture (SBA) and savanna native forest (SNF) in northeastern Brazil. Soil samples were collected at 0-0.05 m, 0.05-0.10 m, 0.10-0.20 m and 0.20-0.40 m depths in the dry and rainy seasons to evaluate total organic carbon (TOC) stocks and labile carbon (LC), fulvic acid fraction (C-FAF), humic acid fraction (C-HAF), humin (C-HF) and microbial biomass carbon (Cmic) contents. Additionally, carbon management index (CMI) was determined. Higher TOC stocks (97.7 and 81.8 Mg ha -1 for the 0-0.40 m depth in the dry and rainy seasons, respectively) and LC, humic substances and Cmic contents were observed in the AFS13 in all the depths. CMI also was higher in the AFS13 (0-0. 05 m: 158 and 86; 0.05-0.10 m: 171 and 67, respectively for the dry and rainy seasons) especially when compared to the SBA (0-0.05 m: 5.6 and 5.4; 0.05-0.10 m: 5.3 and 5.8, respectively for dry and rainy seasons). The agroforestry systems increased soil quality through the conservation of organic matter and can be considered an excellent strategy to assurance sustainability in tropical soil of Northeastern Brazil Palavras-chave: Soil quality; Microbial biomass; Carbon management index. 0-0,05 m; 0,05-0,10 m; 0,10-0,20 m; e 0,20-0,40 5 m: 158 e 86, 0,10 m: 171 e 67, respectivamente, nas estações seca e chuvosa), especialmente quando comparado com 05 m: 5,6 e 5,4; 0,10 m: 5,3 e 5,8, respectivamente, nas FRAÇÕES DA MATÉRIA ORGÂNICA DO SOLO NO CERRADO SOB SISTEMA AGROFLORESTAL NO NORDESTE DO BRASIL ABSTRACT -Este estudo teve como objetivo quantificar os estoques de carbono orgânico total e de suas frações em um argissolo sob sistemas agroflorestais com 6 (SAF6) e 13 anos de idade (SAF13), agricultura de corte-e-queima (ACQ) e floresta nativa de Cerrado (FNC) no Nordeste do Brasil.
