Ammonia volatilization in no-till system in the south-central region of the State of Paraná, Brazil Volatilização de amônia em plantio direto na região centro-sul do Paraná

Revista Brasileira de Ciência do Solo, 2010
Ammonia (NH3) volatilization can reduce the efficiency of urea applied to the surface of no-till (NT) soils. Thus, the objectives of this study were to evaluate the magnitude of NH3 losses from surface-applied urea and to determine if this loss justifies

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Subsurface banding increases ammonia emissions under rainfed cotton in Florida sandy soils

Frontiers in Agronomy
Ammonia (NH3) volatilization is a significant pathway for nitrogen (N) loss. The acidic, sandy soils of Florida offer ideal conditions for NH3 losses in rainfed cotton production systems.

Coal char affects soil pH to reduce ammonia volatilization from sandy loam soil

Agrosystems, Geosciences & Environment, 2020
Ammonia (NH3) volatilization loss adversely affects N availability in soil‐plant systems, reduces crop yield, and negatively impacts environment. Char (coal combustion residue), which contains up to 293 g kg−1 total C by weight, has been shown to reduce ...
