Resumo: | The central Brazilian Savanna biome, known as Cerrado, has a vast area of pastures affected by some degree of degradation, where one of the main challenges is incorporating these areas into a crop production system. This study aimed to evaluate the effect of pasture renewal systems on the microbiological and structural quality of a medium-texture Oxisol. A randomized blocks design was adopted, with four replications and eight pasture renewal systems: 1) soybean/off-season maize/soybean; 2) soybean/maize-grass intercropping/soybean; 3) grass for 10 months and then one soybean crop; 4) grass + rattlepod for 10 months and then one soybean crop; 5) grass for 13 months and then one soybean crop; 6) grass + rattlepod for 13 months and then one soybean crop; 7) one soybean crop; 8) original pasture (control). The microbiological quality was assessed based on soil microbial biomass carbon, soil microbial activity, microbial metabolic quotient - qCO2 and activity of the β-glucosidase enzyme; and the structural quality based on the soil structural quality index. The implementation of pasture renewal systems with grass as a single crop (systems 3 and 5) or intercropped with rattlepod (systems 4 and 6) improves the soil microbiological and structural quality. The pasture renewal system beginning with soybean/off-season maize succession (system 1) is not indicated for the medium-texture soil evaluated in this study. KEYWORDS: Rapid soil structure diagnosis, β-glucosidase, soil microbial biomass. |

Microbiological and structural quality of Oxisol under pasture renewal systemsQualidade microbiológica e estrutural de Latossolo submetido a sistemas de renovação de pastagemThe central Brazilian Savanna biome, known as Cerrado, has a vast area of pastures affected by some degree of degradation, where one of the main challenges is incorporating these areas into a crop production system.

KEYWORDS: Rapid soil structure diagnosis, β-glucosidase, soil microbial biomass.O Cerrado brasileiro possui vasta área ocupada por pastagens com algum grau de degradação, e um dos principais desafios está na incorporação dessas áreas a um sistema produtivo. Objetivou-se avaliar o efeito de sistemas de renovação de pastagem na qualidade microbiológica e estrutural de um Latossolo de textura média. O delineamento experimental foi em blocos ao acaso, com quatro repetições e oito sistemas de renovação de pastagem: 1) soja/milho safrinha/soja; 2) soja/consórcio milho-capim/soja; 3) 10 meses de capim e uma safra de soja; 4) 10 meses de capim + crotalária e uma safra de soja; 5) 13 meses de capim e uma safra de soja; 6) 13 meses de capim + crotalária e uma safra de soja; 7) uma safra de soja; 8) pasto original (testemunha). A qualidade microbiológica foi avaliada por meio do carbono da biomassa microbiana do solo, atividade microbiana do solo, quociente metabólico - qCO2 e atividade da enzima β-glucosidase, e a qualidade estrutural por meio do índice de qualidade estrutural do solo. A implantação de sistemas de renovação de pastagem com capim solteiro (sistemas 3 e 5) ou consorciado com crotalária (sistemas 4 e 6) melhora a qualidade microbiológica e estrutural do solo. A renovação de pastagem iniciada com sistema de sucessão soja-milho safrinha (sistema 1) não é indicada para o solo de textura média avaliado neste estudo.
