Use of ammonium sulphate as a sulphur fertilizer: Implications for ammonia volatilization [PDF]
Soil Use and Management, 2021 Ammonium sulphate is widely used as a sulphur (S) fertilizer, constituting about 50% of global S use. Within nitrogen (N) management it is well known that ammonium-based fertilizers are subject to ammonia (NH3) volatilization in soils with pH >7, but ...

Ammonia volatilization from a piggery pond
Water Science and Technology, 1996 There is a need to improve the performance of agricultural wastewater stabilization ponds. In particular, a better understanding of the relative importance of the nitrogen removal mechanisms is required.

Nitrogen removal via ammonia volatilization in maturation ponds
Water Science and Technology, 2007 A simple apparatus was designed to collect ammonia gas coming out from waste stabilization ponds (WSP). The apparatus has a capture chamber and an absorption system, which were optimized under laboratory conditions prior to being used to assess ammonia ...

MANAGEMENT OF IRRIGATION AND NITROGEN FERTILIZERS TO REDUCE AMMONIA VOLATILIZATION [PDF]
Revista Brasileira de Ciência do Solo, 2015 Nitrogen losses by ammonia (NH3) volatilization can be reduced by appropriate irrigation management or by alternative N sources, replacing urea. The objective of this study was to evaluate the efficiency of irrigation management and N source combinations

Ammonia volatilization from coated urea forms [PDF]
Revista Brasileira de Ciência do Solo, 2013 Nitrogen fertilization is a major component of the cost of agricultural production, due to the high cost and low efficiency of fertilizers. In the case of urea, the low efficiency is mainly due to losses by volatilization, which are more pronounced in ...

Ammonia volatilization from composting with oxidized biochar [PDF]
Journal of Environmental Quality, 2020 AbstractAnimal manure, agricultural residues, and other sources of biomass can be diverted from the waste stream and composted into valuable fertilizer. However, composting often results in substantial N loss through NH3 gas volatilization. We investigated biochar's capacity to improve NH3–N retention during composting of poultry manure and straw ...

Effect of Ammonia on the Volatility of Organic Diacids
Environmental Science & Technology, 2014 The effect of ammonia on the partitioning of two dicarboxylic acids, oxalic (C2) and adipic (C6) is determined. Measurements by a tandem differential mobility analysis system and a thermodenuder (TD-TDMA) system are used to estimate the saturation vapor pressure and enthalpy of vaporization of ammonium oxalate and adipate.
