Abstract: A rápida nitrificação do nitrogênio (N) amoniacal de fontes orgânicas e minerais no solo pode resultar em perdas de nitrato (NO3-) para o ambiente. Uma estratégia para a redução dessas perdas envolve o uso de inibidores de nitrificação. O objetivo do presente trabalho foi o de avaliar, em condições de laboratório, a eficiência da dicianodiamida (DCD), presente no produto Agrotain® Plus (AP), em inibir a nitrificação do N amoniacal de cama de aviário (CA) no solo. Foram avaliados cinco tratamentos, sendo um com… Show more

“…For the poultry litter, it was observed a decrease of the ammonia based nitrogen and, on the other hand, an increase of N in the nitrate form, as observed by Sistani et al (2008). Azeez & Averbeke (2010), observed a rapid mineralization of organic N by soil microorganisms; the N in ammonia form is a result of this process of the nitrification in the soil, which was also observed by Aita et al (2013) in their study. Agehara & Warncke (2005) observed that during the incubation process for poultry litter in two distinct phases, a fast mineralization of organic N occurred in the first two weeks, followed by a slow phase with lower increased rate.…”

“…The similarity among the nitrogen sources at the depths of 5, 10, 15 and 20 mm in the three soil layers may be related to the short period between the fertilizer application and the evaluation of the nitric nitrogen content. This similarity occurs because the rate of nitrification in unplowed soils is low, varying from zero to slightly more than 1 kg ha -1 day -1 (Cardoso et al, 2006), and because the temporary microbial immobilization of ammonia nitrogen can also retard the nitrification process (Aita et al, 2013).…”

“…De acordo com Correa e Miele (2011) a adubação com cama de aves quando efetuada de maneira adequada promove um acréscimo no potencial de produção agrícola. Entre os nutrientes presentes na cama de frango o nitrogênio está em maior concentração, devido à dieta das aves o que foi confirmado na análise dos macronutrientes dos cladódios das duas variedades em nosso experimento (Aita et al, 2013).…”
