“…Interestingly, reducing the temperature inside barns is one of the proposed strategies to increase the activity of microbes responsible for reducing the gaseous NH 3 concentration and nuisance odor [45]. McCrory et al suggested that higher temperatures inside storage barns favor the dominant pathway of NH 3 production [43], and Bleizgys et al [46] stated that reducing the temperature inside barns could be an excellent way to reduce NH 3 emissions. The above strategies align with the results of the current study, as seaweed masking decreased the barn temperature, consequently reducing gaseous NH 3 and amine emissions and eliminating the nuisance odor.…”

Manures from livestock industries and farmyards should be managed for land application. Currently, a deep pit or barn system is adopted by many swine farms for manure management, therefore releasing harmful gases and rising the total global emissions of GHGs. This research focuses on the effectiveness of the brown seaweed Sargassum horneri as a masking agent to mitigate odor-generating gaseous pollutants and reduce the emissions of volatile fatty acids (VFAs) from swine manure storage facilities. Using an optimized procedure, we compared the gaseous emissions from two manure storage barns, one containing swine manure masked with S. horneri and the other without masking as a control, over a 30-day period. The results showed that, compared to the control, seaweed masking significantly reduced the sulfide and VFA contents. Furthermore, reductions of 99.48% in H2S, 60 ± 5.21% in NH3 and 74.28 ± 2.14% in gaseous amine emissions were observed within the experimental period. Intriguingly, seaweed masking had beneficial effects, decreasing the total odor content by 97.78 ± 3.15% and increasing the nutrient quality of the manure. S. horneri has great potential as a masking agent in swine manure management to control environmental pollution.

“…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.…”

“…The laboratory tests have verified the effect of these factors. It was established that higher air and manure surface temperature resulted in an exponential increase in ammonia emissions [5], while the dependence of emission on the air velocity was best expressed by a second-degree polynomial [4]. At the same time, excessive ventilation reduction leads to the indoor air quality degradation [9].…”

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.

“…Sutton et al (2013) concluded from the results of various field campaigns that the percentage of N volatilized as ammonia increased exponentially as a function of average temperature Bleizgys et al (2013). also found similar correlations from experiment results from a naturally ventilated open cowshed lab, namely, ammonia increased emission gains at higher temperatures.…”

Improving the spatial and temporal variability of ammonia emissions from agriculture in Western Europe

allocation was improved by the implementation of the TIMELINES module, which correlates the timing of manure and fertilizer application with meteorology. The method produced an annual emission map and spatially explicit time profiles for Germany and the Benelux for 2010. The newly derived emission information was imported into LOTOS-EUROS to model the ammonia surface concentration and total column distributions. The validation with in situ measurements showed that the model performance improves significantly with respect to the temporal variation of ammonia concentrations in comparison to the simulation with static emission profiles. The comparison with satellite observations confirmed these results and identified an overestimation of ammonia concentrations in Southern Germany and an underestimation in Northern Germany. The conclusion was that the spatial details on the data input needed to be refined further, including crop and livestock distributions, excretion rates, emissions fractions, and the locations of animal houses.Chapter 3 builds on the work described in Chapter 2 and assesses how the spatial allocation in the ammonia emission modeling can be improved by using publicly available crop maps with higher spatial resolution and livestock number data from national registries for the Netherlands, Denmark, and Portugal. Livestock distributions affect the spatial distribution of excreted N and thus ammonia emission, while detailing the crop distribution affects both the spatial and temporal distributions of application emissions. Emission fractions were also updated using the results of local experiments. The differences in the spatial distribution of ammonia emissions are more evident in the animal housing and manure sectors than in the manure and fertilizer application sectors because the changes in animal number data were greater than that in crop distribution. At the same time, the adapted emission distributions show more spatial details because emissions from manure and fertilizer application to crops are only allocated to where the respective crops are grown. The emissions from the standard INTEGRATOR model and the adapted approaches were validated by comparing surface concentrations predicted with LOTOS-EUROS with in situ observations. The validation was made for springtime and wintertime separately to investigate the improvements brought by crop maps and livestock information. The results show that the inclusion of such data has improved both the spatial and temporal distribution of ammonia emissions. However, uncertainties in the spatial and temporal distribution of ammonia emissions remain, which are caused by not accounting for the exact locations of animal houses and the spatial variation in meteorological conditions, application techniques, manure composition, and soil properties. Moreover, the lack of in situ measurement data only allowed model validation for the Netherlands. Last, it has to be noted that crop maps are not always publicly available for other countries, which means that crop mappi...
