Resumo: | The purpose of the present study is to evaluate the influence of different handling systems, the microbial population and its activity. To that end, soil samples were collected in October 2006 and March 2007, at Fazenda Sereno in the city of Jaciara, Mato Grosso State. The samples were removed at 0-10 cm deep with four replications in five areas with different handling systems: agriculture-livestock integration, corn/soy fields, pastures, native vegetation, and native vegetation under recovery. The method of Chloroform Fumigation-Incubation (CFI) was used to evaluate microbial biomass carbon (MBC) and microbial respiration (MR). The qCO2 was obtained through the relationship between MR and MBC. The averages were compared through the Scott-Knott test at 5%. During the analyses, it was observed that the different agricultural practices substantially affect the soil, causing disturbances in the microbial community, which may influence the biogeochemical processes occurring on the soil. The data obtained also makes it possible to conclude that: in the agriculture-livestock integration and pasture systems, the microbial population is influenced by collection times. In this work, in the field-livestock integration system, the microbial activity is constant at the different collection times and management systems influence the metabolic activity of microorganisms in the soil. |

Para tal, foram coletadas, em outubro de 2006 e março de 2007, amostras de solo na Fazenda Sereno no Município de Jaciara, Estado do Mato Grosso. Retirou-se amostras de solo na profundidade de 0-10 cm, com quatro repetições em cinco áreas com diferentes sistemas de manejos: integração lavoura-pecuária, lavoura de milho/soja, pastagens, vegetação nativa e vegetação nativa em recuperação. Para avaliar o carbono da biomassa microbiana (CBM) e a respiração microbiana (RM) foi utilizado o método do Clorofórmio Fumigação-Incubação (CFI). Já o qCO2 foi obtido pela relação entre a RM e o CBM. As médias foram comparadas pelo teste de Scott-Knott a 5%. No decorrer das análises, pôde-se observar que as diferentes práticas agrícolas afetam fortemente o solo causando distúrbios na comunidade microbiana que podem, por sua vez, influenciar os processos biogeoquímicos que nele ocorrem. Os dados obtidos permitem, ainda, concluir que: nos sistemas Integração lavoura-pecuária e pecuária a população microbiana é influenciada pelas épocas de coletas. Nesse trabalho, no sistema Integração lavoura-pecuária a atividade microbiana é constante nas diferentes épocas de coleta e os diferentes sistemas de manejos influenciam a atividade metabólica dos microrganismos presentes no solo.Universidade Estadual de Maringá2011-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/484110.4025/actasciagron.v33i2.4841Acta Scientiarum.
