“…Under tropical conditions, increases in C and N microbial (Schjønning et al, 2004). biomasses under no-tillage have been observed mainly at 0-10 cm of soil depth Balota et al, 2003;Silva et al, 2010). Soil microbial biomass is affected not only by the soil management system, but also by the composition of plant species in the crop rotation system (Silva et al, 2010).…”

“…biomasses under no-tillage have been observed mainly at 0-10 cm of soil depth Balota et al, 2003;Silva et al, 2010). Soil microbial biomass is affected not only by the soil management system, but also by the composition of plant species in the crop rotation system (Silva et al, 2010). Under semiarid conditions and different tillage systems (disk ploughing, animal-drawn ploughing and minimum tillage) in Mexico, the soil microbial biomass carbon and organic carbon were identified as a minimum data set as potential indicators for soil health assessment (along with soil pH and exchangeable Mg 2+ ) in Agave angustifolia plantations, showing that these soil attributes are closely related and capable of distinguishing the sites and their associated tillage systems (Bautista-Cruz et al, 2011).…”

“…No entanto, sistemas de manejo que promovem mínima perturbação do solo, como o plantio direto associado a práticas conservacionistas, tendem a melhorar a fertilidade (Karlen et al, 2013), estrutura do solo (Vezzani e Mielniczuk, 2011) e atividade biológica (Franchini et al, 2007;Silva et al, 2010a), mantendo ou melhorando o equilíbrio e, consequentemente, a QS (Vezzani e Mielniczuk, 2009 Lourenzi et al, 2013). Estudos têm demonstrado que sucessivas aplicações de DLS em superfície, sob sistemas sem revolvimento, promovem alterações nas propriedades do solo, como: melhorias da fertilidade nas camadas superficiais do solo, especialmente daqueles nutrientes com menor mobilidade (Scherer et al, 2010;Guardini et al, 2012;Lourenzi et al, 2013); pouco ou nenhum efeito sobre os teores de carbono orgânico (Arruda et al, 2010;Scherer et al, 2010;Brunetto et al, 2012) e atributos de acidez do solo ; favorecimento da atividade microbiológica (Balota et al, 2012) e abundância de organismos no solo ; e manutenção da qualidade estrutural do solo (Arruda et al, 2010).…”

“…Os teores obtidos estão de acordo com os valores encontrados em outros trabalhos para diferentes culturas e condições climáticas (BALOTA et al, 1998;HAYNES, 2006;HUNGRIA et al, 2009;SILVA et al, 2010;SANTOS, et al, 2012b (BALOTA et al, 1998). Embora seja esperado que a biomassa microbiana seja maior em solo argiloso pela maior retenção da matéria orgânica do solo (SUGIHARA et al, 2010), nossos resultados mostraram que o solo arenoso respondeu mais expressivamente à alteração de manejo da palha.…”
