Legal Requirements on Ammonia Emissions from Animal Production Buildings in Eur...
Bjerg, B.; Demeyer, P.; Hoyaux, J.; Didara, M.; Grönroos, J.; Hassouna, M.; Amon, B.; Bartzanas, T.; Sándor, R.; Fogarty, M.; Klas, S.; Schiavon, S.This chapter gathers information about the current legal requirements related to the emission of ammonia from animal housing in 24 out of the 27 EU countries and in 7 non-EU countries. Overall, the chapter shows that most of the included countries have established substantial procedures to limit ammonia emission and practically no procedures to limit greenhouse gas emission. The review can also be seen as an in...
The Implications of Animal Manure Management on Ammonia and Greenhouse Gas Emis...
Fangueiro, D.; Merino, P.; Pantelopoulos, A.; Pereira, J.L.S.; Amon, B.; Chadwick, D.R.High livestock densities and the subsequent generation of large quantities of manure, in some areas of the world, generate hotspots of increased environmental risks through ammonia (NH3) and greenhouse gas (methane, CH4; nitrous oxide, N2O) emissions. Livestock production is therefore facing increased pressures from society to comply with environmental legislation, so that production systems are managed in a su...
Estimating soil organic carbon of sown biodiverse permanent pastures in Portuga...
Morais, Tiago; Tufik, Camila; Rato, A.; Rodrigues, N.; Gama, I.; Jongen, M.; Serrano, João; Fangueiro, D.; Domingos, T.; Teixeira, R.Grasslands in Portugal are key managed ecosystems, supporting and providing a diverse number of ecosystem services. Here, we developed a procedure for rapid estimation of soil organic carbon (SOC) in soil samples of sown biodiverse permanent pastures rich in legumes (SBP) in Portugal. We combined laboratory NIR spectral data analysis with artificial neural networks (ANN) to estimate the SOC content of SBP soil ...
Nitric oxide and nitrous oxide emissions from cattle-slurry and mineral fertili...
Pereira, J.; Coutinho, J.; Fangueiro, D.; Trindade, H.The application of organic and mineral fertilisers to soil can result in increased gaseous emissions to the atmosphere such as nitric oxide (NO) and nitrous oxide (N2O) gases. The aim of this study was to evaluate under laboratory conditions the effects on mineral N dynamics and NO and N2O emissions of application to soil of cattle slurry derived liquid fraction (LF) obtained by screw press and mineral fertilis...
Effects of cattle-slurry treatment by acidification and separation on nitrogen ...
Fangueiro, D.; Pereira, J.; Bichana, A.; Surgy, S.; Cabral, F.; Coutinho, J.Cattle-slurry (liquid manure) application to soil is a common practice to provide nutrients and organic matter for crop growth but it also strongly impacts the environment. The objective of the present study was to assess the efficiency of cattle-slurry treatment by solideliquid separation and/or acidification on nitrogen dynamics and global warming potential (GWP) following application to an acidic soil. An ae...
Impact of cattle slurry treatment by separation and acidification on gaseous em...
Fangueiro, D.; Pereira, J.; Bichana, A.; Surgy, S.; Cabral, F.; Coutinho, J.Objectives: Cattle-slurry management became a priority in many livestock farms and slurry treatment is used to increase the fertilizer value of slurry and/or minimize its environmental impact. Indeed, significant emissions of ammonia (NH3) and greenhouse gases (GHG) as nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4) can occur during and after slurry application to soil. Application of acidified slur...
Técnicas de aplicação de chorume no solo e eficiência do uso do N pelas culturas
Carneiro, J.; Soares, D.; Monteiro, J.; Surgy, S.; Pereira, J.; Coutinho, J.; Trindade, H.; Fangueiro, D.Técnicas de aplicação de chorume ao solo e eficiência do uso do N pelas culturas

Impact of slurry management strategies on potential leaching of nutrients and p...
Fangueiro, D.; Surgy, S.; Napier, V.; Menaia, J.; Vasconcelos, E.; Coutinho, J.For farmers, management of cattle slurry (CS) is now a priority, in order to improve the fertilizer value of the slurry and simultaneously minimize its environmental impact. Several slurry pre-treatments and soil application methods to minimize ammonia emissions are now available to farmers, but the impact of such management strategies on groundwater is still unclear. A laboratory experiment was performed over ...
Effect of the pig slurry separation techniques on the characteristics and poten...
Fangueiro, D.; Lopes, C.M.; Surgy, S.; Vasconcelos, E.Solid-liquid separation of slurry is used to obtain a solid (SF) and liquid fraction (LF), both used as organic fertilisers. Previous works showed that the separation technique used influences the composition of the resulting SF but no data are available relative to the LF. Four commonly used separation processes were considered e centrifugation, sieving, enhanced settling by the addition of cationic polyacryla...
