Evaluation of microbial activity, N-NH3 and CO2 losses in poultry litter treated with basalt rock powder

open access: yesInternational Journal of Recycling of Organic Waste in Agriculture, 2023
Purpose Poultry litter (PL) and basalt rock powder (BRP) are raw materials highly produced in some Brazilian regions. The association of these products can generate greater added value for the agribusiness chain and be a sustainable source of fertilizer.Method The experiment consisted of an incubation trial over time for chemical characterization of ...

Mathematical models for adjustments in the quantification of ammonia volatilization from urea fertilizer applied on tropical pastures

open access: yesCiência Rural, 2023
: In Brazil, urea is the most used nitrogen (N) fertilizer to improve forage production. However, their excessive use can cause environmental impacts through N losses, such as ammonia (NH3) volatilization.

Ruminal pH and N-NH3 behavior: a Bayesian approach

open access: yesSemina: Ciências Agrárias, 2016
In this work, we present the Bayesian approach as an alternative to frequentist analysis regarding correlated data of pH and N-NH3 in the Holstein cow rumen. It was observed that for pH and N-NH3 data, a posteriori estimates of coefficients of the regression models were significant, which was not observed for least-squares estimates. Thus, the Bayesian

Volatilização de N-NH3 de fontes nitrogenadas em cana-de-açúcar colhida sem despalha a fogo [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2003
Com a colheita da cana sem queima, espessa camada de palha é depositada sobre o solo. A presença da palha modifica o agroecossistema, exigindo reformulação na tecnologia de manejo da cultura. Na adubação nitrogenada da cana-de-açúcar, a uréia é a fonte de N mais utilizada e, quando aplicada sobre a palha, apresenta elevadas taxas de perda de N-NH3 por ...
