Ammonia emission and moisture evaporation from manure affect the climate inside the cow barn. According to our previous study, the manure surface area is of greater importance than its layer thickness in this respect. However, in practice, the manure passage area cannot be reduced in the loose housing of cows in cubicles. Therefore, other factors contributing to emission abatement are to be considered. The study objective was to identify the relation between the ammonia emission and moisture evaporation from cattle manure and the manure moisture and excrement content. For this purpose, a laboratory-scale set-up was designed. It consisted of a case with a fan installed and an exhaust pipe with a gas detector and an air velocity transmitter. The initial relative moisture content of cow excrement was 89 %. Peat with 57 % moisture content was added to reduce it, and tap water was added to increase it. The mass of each sample was 1 kg. In the experiment, the tested sample was placed in the set-up; the air was blown over its surface by the fan and the sensors in the pipe recorded the ammonia concentration and the airflow rate. Each experiment lasted for 30 minutes. The ammonia emission was calculated by the common methodology. The moisture evaporation was determined by the change in the sample mass during the experiment. The study results showed that the average ammonia emission from the initial excrement with 89 % moisture content was 68.26 mg•h -1 . When peat was added and the mixture moisture content reduced to 84 %, the average ammonia emission was 41.57 mg•h -1 . When water was added and the mixture moisture content increased to 94 %, the average ammonia emission was 32.93 mg•h -1 . In terms of the excrement unit, the ammonia emission decreased by 30.1 % when peat was added and only by 9 % when water was added. Therefore, the animal housing on bedding is preferable to reduce the ammonia emission from manure and to create a more favorable climate in the cow barn.

“…Lowering the cow barn temperature and the airflow rate above the manure surface [4][5][6], as well as cutting the manure-soiled area [7; 8] may reduce the ammonia emissions. The laboratory tests have verified the effect of these factors.…”

“…Information regarding measuring methods for NH3 emissions is also included in Table 1. NH3 concentration was mainly measured by photoacoustic methods (Adviento-Borbe et al, 2010;Leytem et al, 2011;Leytem, Dungan, Bjorneberg, & Koehn, 2012;Ngwabie, Jeppsson, Gustaffson, & Nimmermark, 2011;Ngwabie, Jeppsson, Nimmermark, Swensson, & Gustafsson, 2009;Ngwabie et al, 2014;Snell, Seipelt, & Van Den Weghe, 2003;Zhang et al, 2005) or by spectroscopy (Bagdonienė and Bleizgys, 2014;Bjorneberg et al, 2009;Gustafsson et al, 2005;Powell et al, 2008a,b). Angrecka and Herbut (2014) and Kavolelis (2006) measured NH3 concentrations using Dräger detectors whereas Flesch et al (2009) and…”

Livestock housing is one of the main sources of ammonia (NH3) emissions from agriculture. Different management and environmental factors are known to affect NH3 emissions from housing systems. The aim of this study was to quantitatively define the effect of temperature, wind speed, relative humidity, and ventilation rate in NH3 release rates from dairy cattle housing by conducting a meta-analysis of published scientific results. A literature survey was performed to review studies published before January 2018 that have identified statistical relationships between NH3 emissions and environmental factors such as air temperature, wind speed, relative humidity, or ventilation rate in dairy cattle housing. Experimental values were related using a mixed model analysis in order to analyze the effect of environmental factors on NH3 emissions. For this exercise, a total of 19 peer-reviewed papers were considered and 27 different relations between air temperature and NH3 emissions were used for the analysis.

“…As the ventilation rate is increased, the concentration of ammonia decreases in a barn whereas, NH3 emission is observed to increase disproportionally (Philippe et al, 2011;Samer et al, 2012). Reduction of air circulation inside dairy barns presents a good potential to reduce atmospheric pollution with ammonia gas from them (Bagdonienė et al, 2014).…”

Experimental studies performed at the laboratory enabled to find out the effect of the biopreparation on the process of ammonia volatilization from manure. Adding biopreparation to manure was found to slow down ammonia emission from manure. Depending on the manure composition, temperature of the environment, and duration of exposure to the biopreparation, the emission was found to decrease by up to 22 %. The maximum effect was observed on the day 6–14, whereas 30 days after biopreparation’s use its effect was significantly decreased. The effect of biopreparation on ammonia volatilization was observed to be higher under more intensive ammonia emissions, i.e. when the manure was fresh, with no crust formed on its surface, under high air flow velocity above the manure and high ammonia concentration gradient in the surface of the manure. Use of the biopreparation is highly recommended for reduction of ammonia emissions in litter-free barns where liquid manure accumulates. Its use is consistent with the modernization tendencies to implement litter-free liquid manure technologies.
