Use of urease inhibitors to reduce ammonia volatilization in Amazonian soils [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2019
: The objective of this work was to evaluate urease inhibitors for the reduction of ammonia volatilization in Amazonian soils. The work was carried out on a clayey yellow Oxisol, a clayey red Oxisol, and on a light silty Ultisol.

Nutrient Release and Ammonia Volatilization from Biochar-Blended Fertilizer with and without Densification

open access: yesAgronomy, 2021
Blending fertilizer with biochar followed by densification to make it into a tablet can enhance the adsorption of fertilizer on the biochar surface and reduce the nutrient loss during handling.

Achieving volatile potassium promoted ammonia synthesis via mechanochemistry

open access: yesNature Communications, 2023
AbstractPotassium oxide (K2O) is used as a promotor in industrial ammonia synthesis, although metallic potassium (K) is better in theory. The reason K2O is used is because metallic K, which volatilizes around 400 °C, separates from the catalyst in the harsh ammonia synthesis conditions of the Haber-Bosch process.

Effects of rice husk biochar in minimizing ammonia volatilization from urea fertilizer applied under waterlogged condition

open access: yesAIMS Agriculture and Food, 2021
Rapid ammonia volatilization from surface applied urea in waterlogged condition is one of the drawbacks as it leads to poor nitrogen use efficiency by plants. Thus, a laboratory scale closed dynamic air flow system was carried out in this study to assess

Evaluation of ammonia volatilization losses by adjusted parameters of a logistic function

open access: yesRevista Brasileira de Ciência do Solo, 2014
The dynamics of N losses in fertilizer by ammonia volatilization is affected by several factors, making investigation of these dynamics more complex. Moreover, some features of the behavior of the variable can lead to deviation from normal distribution ...

Loss of ammonia from nitrogen fertilizers applied to maize and soybean straw

open access: yesRevista Brasileira de Ciência do Solo, 2013
In Brazilian agriculture, urea is the most commonly used nitrogen (N) source, in spite of having the disadvantage of losing considerable amounts of N by ammonia-N volatilization.

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.

An improved mechanistic model for ammonia volatilization in Earth system models: Flow of Agricultural Nitrogen version 2 (FANv2)

open access: yes, 2020
. Volatilization of ammonia ( NH3 ) from fertilizers and livestock wastes forms a significant pathway of nitrogen losses in agricultural ecosystems and constitutes the largest source of atmospheric emissions of NH3 .
