| Resumo: O objetivo deste trabalho foi avaliar o efeito do manejo de plantas de cobertura na floração e na maturação fisiológica sobre a produtividade do milho cultivado em sucessão. O experimento, em delineamento de blocos ao acaso com parcelas subdivididas, foi realizado em Latossolo Vermelho, em sistema plantio direto, com nove espécies. Foram avaliados: produtividade de matéria seca; tempo de ciclagem dos resíduos vegetais; teores de N das plantas de cobertura; e produtividade de grãos e teores de N nas folhas do milho. As espécies Pennisetum glaucum, Mucuna aterrima, Cajanus cajan e Canavalia brasiliensis apresentaram as maiores produtividades de matéria seca na floração. Na maturação fisiológica, Sorghum bicolor, P. glaucum, C. brasiliensis,... |

| Abstract The objective of this work was to evaluate the dynamics of soil microbiological attributes under integrated production systems, continuous pasture, and native cerrado. The study was conducted in a transition area from crop to livestock. Four areas with different land uses were evaluated: an integrated crop-livestock-forestry system (ICLFS), cultivated with Eucalyptus urograndis alley cropping, spaced 2x2 m between plants and 22 m between alleys; an integrated crop-livestock system (ICLS); besides two adjacent areas of native cerrado and continuous pasture, used as a reference. For the assessment of microbiological attributes, soil samples were taken in the 0.00-0.10, 0.10-0.20, and 0.20-0.30-m layers, in February 2012 and February 2014 (rainy... |

| The aim of the present study was to evaluate the effects of cover crops on the soil's chemical fertility, in particular its carbon and nitrogen content, in a Typic Acrustox under conventional and no-tillage corn systems. We hypothesized that the no-tillage system associates with cover crops maintains or increases soil carbon and nitrogen stocks and enhance soil fertility. The no-tillage system did not present higher carbon and nitrogen stocks than conventional tillage, but resulted in higher concentrations of exchangeable bases, higher CEC, and higher base saturation in the surface soil layer, mainly under use of Canavalia brasiliensis. Carbon and nitrogen stocks (up to 40 cm depth) differ significantly between the different cover crop species. The use of... |
