| RESUMO O uso de dejetos líquidos de suínos como fertilizante do solo é uma prática comum na Região Sul do Brasil. Apesar de ter benefícios na reutilização dos dejetos, essa prática apresenta sérios riscos ambientais. Os indicadores microbiológicos de qualidade do solo são bastante sensíveis e permitem o monitoramento das condições do ambiente edáfico. Objetivou-se avaliar a qualidade microbiológica do solo de pastagens com diferentes históricos de uso sucessivo de dejetos líquidos de suínos. Determinaram-se o teor de C da biomassa microbiana, a respiração microbiana do solo, o quociente metabólico (qCO2) e a atividade das enzimas β-glicosidase, urease e hidrólise do diacetato de fluoresceína (FDA), em áreas de pastagem com uso de dejetos de suínos há dois... |

| Abstract The sweet potato (Ipomoea batatas L.) is a vegetable of great economic importance since it can be used for in natura consumption, for processing in agribusiness and/or biofuel production. The objective of this work was to evaluate the yield of three sweet potato cultivars: BRS Amelia, BRS Cuia and BRS Rubissol in the Northwest Region of Rio Grande do Sul. The experiment was conducted in the field for two consecutive years (harvests 2014/2015 and 2015/2016). The experimental design was in randomized blocks, evaluating 3 sweet potato cultivars for 2 agricultural years, with 4 replications. As results, it was observed that potato weights in the first year of study ranged from 272.0 g to 320.2 g. In the second year of evaluation, it ranged from 133.9... |

| ABSTRACT: The successive application of pig slurry to pastures is a common practice in southern Brazil, serving as a method of waste disposal as well as an important alternative to chemical fertilization. Although there are economic benefits to the use of manure as fertilizer, it may be associated with environmental hazards and cause changes to composition and activity of soil fauna. This study aimed to study the effects of pig slurry on the soil biota of pastures. Composition and biological activity of pastures where manure was applied successively for 2 years (A2) and 14 years (A14) were evaluated, and native forest (NF) was analyzed as a reference area. Successive application of pig slurry to the soil changed its biological characteristics according to... |
