Plant uptake of nitrogen adsorbed to biochars made from dairy manure

Scientific Reports, 2021
The conversion of dairy waste with high moisture contents to dry fertilizers may reduce environmental degradation while lowering crop production costs. We converted the solid portion of screw-pressed dairy manure into a sorbent for volatile ammonia (NH3)

Significant reduction of ammonia emissions while increasing crop yields using the 4R nutrient stewardship in an intensive cropping system

Journal of Integrative Agriculture, 2023
Ammonia (NH3) emissions should be mitigated to improve environmental quality. Croplands are one of the largest NH3 sources, they must be managed properly to reduce their emissions while achieving the target yields.

Effect of source and level of forage in the diet on in vitro ammonia emission from manure of Holstein and Jersey dairy cows

JDS Communications, 2021
Reducing overall reactive N losses from dairy production systems depends substantially on reducing the atmospheric emission of manure ammonia (NH3). The objective of this study was to determine potential NH3-N emission of reconstituted manure using an in

Volatilização de N-NH3 na cultura de milho: I. efeito da irrigação e substituição parcial da uréia por sulfato de amônio [PDF]

Revista Brasileira de Ciência do Solo, 1997
Foi desenvolvido um experimento em latossolo vermelho-escuro muito argiloso fase cerrado, no Centro de Pesquisas Novartis-Seeds, Uberlândia (MG), para avaliar o efeito da irrigação e do N-uréia, em cobertura no milho, e de sua substituição parcial por sulfato de amônio, nas perdas de N-NH3 volatilizado.

Accuracy of the estimates of ammonia concentration in rumen fluid using different analytical methods

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
The accuracy of two different methods in measuring the ammonia nitrogen (N-NH3) concentration in rumen fluid were evaluated: a catalyzed indophenol colorimetric reaction (CICR) and the Kjeldahl distillation (KD).

Volatilização de N-NH3 em decorrência da forma de aplicação de uréia, manejo de resíduos e tipo de solo, em laboratório [PDF]

Ciência Rural, 2003
A volatilização de amônia (NH3) é a principal perda de nitrogênio (N) responsável pela baixa eficiência da uréia aplicada na superfície do solo. Este trabalho objetivou avaliar os efeitos do modo de aplicação da uréia e da forma de manejo dos resíduos de aveia preta sobre a volatilização de amônia, em dois solos com diferentes teores de argila e ...
