Average dry matter yield for the control without fertilization in the period 1991{\textendash}2002 was 11.67 t of dry matter per ha, which was by 2{\textendash}2.9 t less than for fertilization treatments. Statistically significant differences between the control and fertilization treatments were determined for the first time in the 4th experimental year. Average nitrogen uptake by the aboveground biomass was 116 kg N/ha for the control, 162{\textendash}170 kg N/ha for fertilization treatments. All experimental treatments had a negative balance of N inputs and outputs, and it was {\textendash}1394 kg N/ha for the control (for 12 experimental years). After the application of mineral fertilizers, a lower content of total carbon and nitrogen was measured in the topsoil compared to the control and treatments with organic fertilization. The changes in the nitrogen regime of soil were characterized by the content of extractable nitrogen and carbon in extractions by 0.01M CaCl2. With respect to the content of mineral nitrogen and easily extractable organic nitrogen and carbon in the topsoil the control was most stable followed by farmyard manure treatment. Soil lysimeters were installed in these experiments (depth 60 cm, size 0.2 m2). For an eight-year period (1994/2002) 11.78 kg N-NO3 {\textendash}/ha were determined in lysimetric waters. These values for fertilization treatments ranged from 21.0 to 58.2 kg N-NO3 {\textendash}/ha. Straw application reduced nitrate contents in lysimetric waters.}, keywords = {EPNB}, author = {Balik, J and Cerny, J and Tlustos, P and Zitkova, M} } @article {75, title = {Processes controlling ammonia emission from livestock slurry in the field}, journal = {European Journal of Agronomy}, volume = {19}, year = {2003}, pages = {465-486}, abstract = {The processes of NH3 emission from field-applied slurry are reviewed and their relative importance assessed. In achieving this objective, the study served to focus on a number of features that have not previously been highlighted. These include the effect of the size of the area to which slurry is applied, the interaction between solar radiation input and wind speed, the role of the solid chemistry and the interaction between slurry NH4 and the slurry/soil cation exchange capacity (CEC). The most important processes controlling NH3 volatilisation were considered to be turbulent and molecular diffusion in the atmosphere, meteorological processes controlling evaporation and surface temperature, the ion production and buffering processes controlling the pH of the slurry/soil liquid, the solid chemistry that determines precipitation of NH4 to slurry dry matter, the physical processes controlling the movement of slurry liquid into and within the soil, and the interaction of slurry liquid with soil CEC.}, keywords = {EPNB}, author = {Sommer, S.

Such integration is important for comprehensive understanding of environmental issues, policy formulation and assessment of trade-offs between different environmental concerns. Here, we systematize published footprint studies and define a family of footprints that can be used for the assessment of environmental sustainability. We identify overlaps between different footprints and analyse how they relate to the nine planetary boundaries and visualize the crucial information they provide for local and planetary sustainability. In addition, we assess how the footprint family delivers on measuring progress towards Sustainable Development Goals (SDGs), considering its ability to quantify environmental pressures along the supply chain and relating them to the water-energy-food-ecosystem (WEFE) nexus and ecosystem services. We argue that the footprint family is a flexible framework where particular members can be included or excluded according to the context or area of concern. Our paper is based upon a recent workshop bringing together global leading experts on existing environmental footprint indicators.}, keywords = {Environmental footprint, Environmental footprint assessment, Family, Footprint, Footprint family, Planetary boundaries}, issn = {00489697}, doi = {10.1016/j.scitotenv.2019.133642}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0048969719335673 https://doi.org/10.1016/j.scitotenv.2019.133642}, author = {Vanham, Davy and Leip, Adrian and Galli, Alessandro and Kastner, Thomas and Bruckner, Martin and Uwizeye, Aimable and van Dijk, Kimo and Ercin, Ertug and Dalin, Carole and Brand{\~a}o, Miguel and Bastianoni, Simone and Fang, Kai and Leach, Allison M. and Chapagain, Ashok and Van der Velde, Marijn and Sala, Serenella and Pant, Rana and Mancini, Lucia and Monforti-Ferrario, Fabio and Carmona-Garcia, Gema and Marques, Alexandra and Weiss, Franz and Hoekstra, Arjen Y.} } @article {AdrianLeip, title = {{The value of manure - manure as co-product in life cycle assessment}}, journal = {Journal of Environmental Management}, volume = {241}, number = {March}, year = {2019}, month = {jul}, pages = {293{\textendash}304}, publisher = {Elsevier}, keywords = {Allocation, Fertilizer, Life cycle assessment, Livestock supply chains, Manure, Nutrients}, issn = {03014797}, doi = {10.1016/j.jenvman.2019.03.059}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0301479719303627}, author = {Leip, Adrian and Ledgart, Stewart and Uwizeye, Aimable and Palhares, Julio C.P. and Aller, Fernanda and Amon, Barbara and Binder, Michael and Cordovil, Claudia M.d.S. and Dong, Hongming and Fusi, Alessandra and Helin, Janne and H{\"o}rtenhuber, Stefan and Hristov, Alexander N. and Koelsch, Richard and Liu, Chunjiang and Masso, Cargele and Nkongolo, Nsalambi V. and Patra, Amlan K. and Redding, Matthew R. and Rufino, Mariana C. and Sakrabani, Ruben and Thoma, Greg and Vert{\`e}s, Fran{\c c}oise and Wang, Ying and Ledgard, Stewart and Uwizeye, Aimable and Palhares, Julio C.P. and Aller, M.
