Resumo: Soil structure has major influence on ecosystem sustainability and plant growth. Arbuscular mycorrhizal fungi (AMF) are an important functional group of soil microbiota, acting in the process of aggregation, especially in agroecosystems and related to the production and plant diversity. AMF are widely distributed in tropical agroecosystems and are extremely important for development of many agricultural crops. The present study evaluated the effect of inoculation with Glomus macrocarpum in different crop sequences on plant growth, microbial activity and aggregation of a Cerrado Oxisol. The study was conducted in a completely randomized design in a4 x 4 factorial scheme. Treatments consisted of four conditions of elimination and/or introduction of AMF (NS-NI: non-sterilized and non-inoculated; NS-I: non-sterilized and inoculated; S-NI: sterilized and non-inoculated; andS-I: sterilized and inoculated) and four crop sequences (Panicum maximum/Panicum maximum, Brachiaria ruziziensis/ soybean, sorghum/soybean and Stylosanthes spp./soybean). Inoculation favored growth of Stylosanthes spp. by increasing plant growth in up to 91% when inoculated. None of the grasses benefited from G. macrocarpum introduction. We observed that G. macrocarpum inoculation associated with indigenous AMF increased microbial biomass, phosphatase activity, mean geometric diameter and mean weighted diameter. The results indicated the beneficial effects of inoculation, which reflected in soil structure improvement and, hence, to agroecosystems sustainability

Os fungos micorrízicos arbusculares (FMAs) constituem um importante grupo funcional da microbiota do solo, atuando diretamente nos processos de agregação, principalmente em agroecossistemas e têm relação direta com a produção e diversidade vegetal. Esses estão amplamente distribuídos no agroecossistemas tropicais e são extremamente importantes para o crescimento de várias espécies vegetais agrícolas. No presente estudo, avaliou-se o efeito da inoculação com Glomus macrocarpum e diferentes sucessões de culturas no crescimento vegetal, na atividade microbiana e na agregação de um Latossolo Vermelho de Cerrado. O estudo foi conduzido em delineamento inteiramente casualizado com arranjo fatorial 4 x 4. Os tratamentos constituíram da combinação entre quatro condições de eliminação e/ou introdução de FMA (NS-NI: não autoclavado-não inoculado; NS-I: não autoclavado-inoculado; S-NI: autoclavado-não inoculado; S-I: autoclavado-inoculado) e quatro sucessões de culturas (Panicum maximum/Panicum maximum; Brachiaria ruziziensis/soja; sorgo/soja; Stylosanthes spp./soja). A inoculação com FMAs favoreceu o crescimento do estilosantes, apresentando aumento de até 91% na produção de massa seca quando inoculado. Nenhumas das gramíneas beneficiaram-se com a introdução de G. macrocarpum. Nós observamos que a inoculação com G. macrocarpum associado aos FMAs indígenas incrementou a biomassa microbiana, atividade da fosfatase ácida, diâmetro médio geométrico e o ponderado. Os resultados indicam os efeitos benéficos da inoculação que reflete na melhoria da estrutura do solo, contribuindo para a sustentabilidadeUniversidade Federal de Lavras2015-12-11T16:56:17Z2015-12-11T16:56:17Z2014-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfVILELA, L.
