Ammonia Volatilization from Urea-Application Influenced Germination and Early Seedling Growth of Dry Direct-Seeded Rice

open access: yesThe Scientific World Journal, 2012
Poor seed germination and early seedling growth associated with urea-induced soil ammonia volatilization are major constraints in the adoption of dry direct-seeded rice.

Reducing Ammonia Volatilization from Urea Fertilizer Applied in a Waterlogged Tropical Acid Soil via Mixture of Rice Straw and Rice Husk Biochars

open access: yesJournal of Agricultural Sciences, 2022
Nitrogen deficiency frequently occurs in agricultural soil because of ammonia volatilization to the environment, resulting in low urea-N use efficiency by plants.

Modeling ammonia emissions from dairy production systems in the United States [PDF]

open access: yes, 2015
Dairy production systems are hot spots of ammonia (NH3) emission. However, there remains large uncertainty in quantifying and mitigating NH3 emissions from dairy farms due to the lack of both long-term field measurements and reliable methods for ...

Simple model for the prediction of ammonia volatilization from water basin: effect of water temperature and pH [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2004
Ammonia is a primary chemical used for preserving rubber latex. Consequently, the wastewater from concentrated rubber latex processing contains high ammonia concentration.

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.

Ammonia volatilization in response to coated and conventional urea in maize crop field

open access: yesBioscience Journal, 2019
The properly measurement of gas emissions and nutrient availability to crops using technologies such as polymer-coated urea are required to monitored the possible nitrogen (N) fertilizer pollution in the environment.

A methodology for estimating the ammonia emission from crop residues at a national scale

open access: yesAtmospheric Environment: X, 2019
Crops and crop residues contribute to pollution of the environment by ammonia (NH3) volatilization. This study focusses on the volatilization from crop residues, defined as residues after a management action or frost i.e.

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.

Ammonia volatilization, nitrogen in soil, and growth of barley after application of peat manure and pig slurry [PDF]

open access: yes, 2006
Peat is added to manure, because its low pH and capacity to adsorb ammonia (NH3) give it potential to reduce nitrogen (N) loss. Peat manure was prepared by mixing pig slurry with moderately humified Sphagnum peat. Less than 1% of applied ammoniacal N was
