Indicadores Microbiológicos de Solo em Pastagem com Aplicação Sucessiva de Dejetos De Suínos

Abstract: 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 … Show more

“…The areas had 0.69, 0.79 and 1.50 ha, respectively. Areas A2 and A14 received during the implantation of pastures, 2 Mg ha -1 of limestone and were managed in a rotational grazing system with dairy cows, receiving annually about 200 kg ha -1 year -1 of urea and 200 m 3 ha -1 year -1 of PS (SILVA et al, 2015).…”

“…In recent years, concern about soil quality (SQ) has grown, since intensive use and mobilization can reduce its ability to maintain a sustainable biological production (CARVALHO et al, 2004;FREITAS et al, 2012). In this sense, the intensive and inadequate use of rural environments makes it necessary to know the processes responsible for the correct management of the soil, being essential to obtain sustainable agricultural production systems (SILVA et al, 2015).…”

“…Os dados obtidos por meio da BMS são indicadores sensíveis que podem ser empregados no monitoramento das alterações ambientais, de forma que modificações nos sistemas de manejo possam ser sugeridas a tempo de evitar a sua degradação (ANDERSON & DOMSCH, 1985;JACOBI & BESEN, 2011;MOREIRA & SIQUEIRA, 2006;SILVA et al, 2015).…”
