Disponibilização dos Nutrientes das Fezes de Bovinos em Pastejo para a Forragem

Abstract: RESUMO -Em local adjacente aos ensaios realizados por Braz et al. (2001) foi estabelecida outra área, com objetivo de avaliar a degradação das placas de fezes depositadas pelos bovinos e a influência dos nutrientes liberados na produção e nos teores de nutrientes da forragem. Foram coletadas 50 placas de fezes imediatamente após a excreção pelo animal e mantidas no campo sob incubação por períodos de 7, 14, 28, 56 e 112 dias. Foi verificada contínua e intensa variação nos teores de potássio das placas, que pa… Show more

“…As a result, K can be readily released from organic residues, either by rain or soil moisture, leading to greater rates of disappearance (Weeda 1967). Braz et al (2002) observed release of 90% of the K in a dung decomposition trial. The author attributed the greater K release rate to the washing of cattle dung pads and their subsequent leaching.…”

“…Tais resultados podem ser explicados pela homogeneidade das condições texturais e pela dinâmica simplificada de liberação de K a partir de resíduos orgânicos (Braz et al, 2002;Eghball et al, 2002;Moreira & Siqueira, 2006;Pitta et al, 2012).…”

“…Potassium (K) normally shows high release rates to the soil since it is not associated with any organic structure [17]. Phosphorus (P), in turn, presents soluble (inorganic) and insoluble (organic) forms, each showing distinct release patterns to the soil [18] and frequently requiring microbial action for mineralization [19].…”
