Abstract: RESUMOEm sistemas de integração lavoura-pecuária, boa parte do suprimento de nutrientes para as pastagens provém das excreções dos animais, na forma de esterco e de urina, o que resulta em estímulo à atividade e ao acúmulo de nutrientes nas suas células. Este estudo foi desenvolvido num experimento de integração lavourapecuária em plantio direto, iniciado em 2001, e objetivou avaliar o impacto de diferentes intensidades de pastejo da pastagem de inverno (aveia-preta + azevém; 10, 20 e 40 cm, e um tratamento se… Show more

“…Thus, the treatment with the highest pasture height and lowest grazing intensity (GI-40) most likely resulted in a decreased water loss and a lower soil temperature, favouring a greater microbial biomass. This result is in accordance with Mercante et al (2008), who evaluated various management systems involving varying cover intensities, and Souza et al 2010, who examined conditions similar to the present study. A decrease in MBC under the highest grazing intensity was also observed by Souza et al (2010) under water stress conditions.…”

“…Carneiro et al (2009) observed lower qCO 2 values for integrated crop-livestock areas relative to a native Cerrado area. A similar result was reported by Souza et al (2010) for a long-term experiment with various grazing intensities. In the GI-20 treatment, as previously mentioned, an abundance of easily decomposable material is created, resulting in a high efficiency of microorganisms for the conversion of the deposited organic wastes.…”

“…Beutler et al (2015) also observed higher concentrations of Pt-H for an NT area with CLI than for native Cerradão (transitional tropical forest). This may be attributed to the annual application of P fertilization, which initially resulted in increased labile inorganic P fractions, and then in increased moderately labile P fractions over time, as a result of P adsorption to iron and aluminum oxides through inner-sphere complex formation (SOUZA, 2008).…”
