Atividade Microbiana Do Solo Com a Aplicação De Esterco Bovino E Efluente De Biodigestor

Abstract: No período de novembro de 1983 a fevereiro de 1984, em Santa Maria. RS, em solo da Unidade de Mapeamento São Pedro (Podzólico Vermelho-amarelo), foi conduzido um experimento de incubação com o objetivo de avaliar o efeito de doses crescentes (9, 18 e 27t/ha), em peso seco de esterco bovino in natura e efluente de biodigestor sobre a atividade microbiana do solo. A atividade microbiana, avaliada através da liberação de CO2 foi proporcional às doses de resíduo orgânico utilizadas. A quantidade de CO2 evoluída em… Show more

“…The first work related to biodigestion was carried out by Sawazaki et al (1985), who discussed the potential of rice husk for the production of biogas through the action of alkaline hydrolysis. The 1990s was a transition period, in which the focus came to be biodigestors (Alta and Frios, 1992;Prada et al, 1998), biogas (Lacerda et al, 1990) and anaerobic biodigestion (Manfron, 1991). After this period, the number of studies increased sharply.…”
