Effect of different substrates on composting of poultry litter

Abstract: -The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The treatments were established according to material used as substrate for broiler litter: treatment 1 -rice husks; 2 -sugar cane bagasse; 3 -wood shavings; 4 -wood shavings + sugar cane bagasse; 5 -rice husks + sugar cane bagasse; and 6 -Napier grass.The following variables were monitored: temperat… Show more

“…The nitrogen is lost by the volatilization of ammonia in alkaline pH, which begins with the hydrolysis of nitrogen composts by microorganisms that degrade organic N, leading to the formation of NH -N (ammonification) (Orrico et al, 2012). However, the C/N ratio is not alone defining whether there is great loss of N during the composting process.…”

“…Já a redução de volume foi semelhante entre as leiras controladas e ao natural, com destaque ao tratamento com palha de trigo (T2), que apresentou a maior redução na leira controlada. Ao longo do processo de compostagem fatores como aeração, degradação de substratos podem interferir (ORRICO, 2012). Na Tabela 5.6 são apresentados os resultados das análises dos compostos finais e os valores limites das variáveis estipuladas pela Instrução Normativa N° 25/2009 do Ministério da Agricultura, Pecuária e Abastecimento (MAPA, 2009) para fertilizantes orgânicos.…”
