Resumo: | Soil attributes may affect the residual activity and impacts of herbicides on non-target organisms. This study aimed to evaluate the residual activity of the sulfentrazone herbicide and its impacts on microbiological parameters of Brazilian Savanna soils, as well as to identify soil attributes that can be used to predict the residual activity of the herbicide in these soils. The experimental design was completely randomized, in a 6 x 5 factorial scheme, with 4 replications, being 5 soil types (Rhodic Acrustox; Typic Quartzpsamment; Rhodic Haplustox; Typic Humaquepts; Fluventic Dystrustepts) and 6 periods (0, 15, 30, 45, 60 and 90 days after herbicide application - DAA). The residual activity of the sulfentrazone herbicide is dependent of the soil type, and the time that the herbicide can control at least 80 % of Urochloa decumbens plants ranges from 0 (Typic Humaquepts) to 38 days (Rhodic Haplustox). The bases saturation is the only soil attribute correlated with the herbicide efficacy over time, in the Brazilian Savanna soils, showing a moderate correlation up to 90 DAA. The pH, organic matter and clay content are not correlated with the herbicide efficacy over time in these soils. Sulfentrazone reduces the microorganisms activity from 45 to 90 DAA in all the studied soils. However, it does not affect the microbial biomass carbon.

Objetivou-se avaliar a atividade residual do herbicida sulfentrazone e seus impactos em parâmetros microbiológicos de solos de Cerrado, bem como identificar atributos do solo que possam ser utilizados para a predição do efeito residual do herbicida nesses solos. Utilizou-se delineamento experimental completamente casualizado, em esquema fatorial 6 x 5, com 4 repetições, sendo 5 tipos de solo (Latossolo Vermelho Ácrico; Neossolo Quartzarênico Órtico; Latossolo Vermelho Distrófico; Gleissolo Melânico Distrófico; Neossolo Flúvico Tb Distrófico) e 6 períodos (0; 15; 30; 45; 60; e 90 dias após a aplicação do herbicida - DAA). A atividade residual do sulfentrazone é dependente do tipo de solo, e o tempo em que é capaz de controlar pelo menos 80 % de plantas de Urochloa decumbens varia de 0 (Gleissolo Melânico Distrófico) a 38 dias (Latossolo Vermelho Distrófico). A saturação por bases é o único atributo do solo correlacionado com a eficácia do herbicida ao longo do tempo, nos solos de Cerrado, apresentando correlação moderada até 90 DAA. O pH, a matéria orgânica e o conteúdo de argila não têm correlação com a eficácia do herbicida ao longo do tempo, nesses solos. O sulfentrazone reduz a atividade de micro-organismos entre 45 e 90 DAA em todos os solos estudados. Entretanto, o carbono da biomassa microbiana não é afetado.
