Perda de amônia por volatilização em pastagem de capim-tanzânia adubada com uréia no verão Ammonia volatilization loss in tanzaniagrass pasture fertilized with urea in the summer

Revista Brasileira de Zootecnia, 2004
Parte do nitrogênio (N) do fertilizante aplicado à pastagem pode ser perdida do sistema e, em pastagens tropicais, a volatilização de amônia (NH3) é uma das principais vias de perda.

Effects of biochar in combination with varied N inputs on grain yield, N uptake, NH3 volatilization, and N2O emission in paddy soil

Frontiers in Microbiology, 2023
Biochar application can improve crop yield, reduce ammonia (NH3) volatilization and nitrous oxide (N2O) emission from farmland. We here conducted a pot experiment to compare the effects of biochar application on rice yield, nitrogen (N) uptake, NH3 and ...

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)
