Summary: | Impacts on the environment and soil biological activity result in changes in the processes of formation of biogenic and fisiogenic aggregates. Aiming to evaluate the influence on physical and biological genesis of aggregates of Cerrado soils and determine the main environmental factors that determine the characteristics of households in the area of production under integrated crop-livestock (ICL), was developed this study in Farm Cabeceira, Maracaju-MS, in areas of ICL. The areas evaluated were: Savana, pasture/maize, corn/cotton and cotton/soybeans being evaluated during the dry (May/2009) and rainy (March 2010) season. To identify the pathways of aggregation were used morphological patterns, and established three clusters: fisiogenic, biogenic and intermediates. The aggregates were analyzed for exchangeable cations, carbon and aggregate stability, soil was analyzed for the exchangeable cations, particle size fractionation of soil organic matter, oxidizable fractions of total organic carbon, particle size analysis and soil macrofauna. In all areas studied, in the dry season, the highest values were quantified aggregate intermediates, while in the rainy season, in general, no differences were observed aggregates formed by different routes in areas except cotton/soybeans. The aggregates showed positive correlation with biogenic carbon and were found in lesser amounts compared to fisiogenic and intermediates. The different types of aggregates formed, besides having different characteristics morphological also differ as to chemical characteristics. |

Com o objetivo de avaliar a influência física e biológica na gênese de agregados dos solos do Cerrado, bem como determinar quais os principais fatores do ambiente que determinam as características dos agregados em área de produção sob sistema de integração lavoura-pecuária (ILP), foi desenvolvido esse trabalho na Fazenda Cabeceira, Maracaju- MS, em áreas de ILP. As áreas avaliadas foram: Cerradão, pasto/milho, milho/algodão e algodão/soja, sendo realizadas avaliações nas épocas seca (maio/2009) e chuvosa (março/2010). Para identificação das vias de agregação foram utilizados padrões morfológicos, sendo estabelecidos três tipos de agregados: fisiogênicos, biogênicos e intermediários. Os agregados foram analisados quanto ao complexo sortivo, carbono e estabilidade, o solo foi analisado quanto o complexo sortivo, fracionamento granulométrico da matéria orgânica do solo, frações oxidáveis do carbono orgânico total, análise granulométrica e macrofauna edáfica. Em todas as áreas estudadas, na época seca, foram quantificados os maiores valores de agregados intermediários, enquanto na época chuvosa, de maneira geral, não foram observadas diferenças dos agregados formados pelas diferentes vias nas áreas, exceto algodão/soja. Os agregados biogênicos apresentaram correlação positiva com teores de carbono e foram encontrados em menor quantidade em comparação aos fisiogênicos e intermediários. Os diferentes tipos de agregados formados, além de apresentarem características morfológicas diferentes, também apresentam diferenças quanto às características químicas.UEL2013-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1061310.5433/1679-0359.2013v34n4p1535Semina: Ciências Agrárias; Vol. 34 No. 4 (2013); 1535-1548Semina: Ciências Agrárias; v. 34 n. 4 (2013); 1535-15481679-03591676-546Xreponame:Semina.
