Lignite improved biogas production during anaerobic digestion of swine manure
• Anaerobic digestion (AD) converts organic waste into biogas, a renewable fuel which is a potential solution for mitigating greenhouse gas emissions and energy crisis. • Poor operational stability, caused by the...
Investigating the fate and behaviour of nitrification inhibitors in soil systems
Increased use of synthetic nitrogen-based (N-based) fertilisers has become a common practice to achieve higher crop yields. However, a large proportion of the applied N is lost to the surroundings via ammonia...
Improving calculation of critical loads with N2O-emission experiments
What are Critical Loads? Long-term exposure to high levels of N has shown impacts on forest growth and biodiversity. It leads to soil acidification and a decline in microbial biomass. To protect forest ecosystems from...
Leaching of nitrogen from polymer coated and stabilized, controlled-release nitrogen fertilizers.
Extensive use of nitrogen fertilizer, coupled with their low nitrogen use efficiencies, cause significant amount of environmental and socio-economic problems worldwide. Use of stabilized and controlled-release nitrogen...
Nitrogen deposition increases sensitivity to drought observed in Swiss forests
•N deposition decreased the growth of European beech in long-term forest observation sites in Switzerland. •Mortality rates of both beech and Norway spruce trees were increased with N deposition. •Drought increased the...
Communicating consequences of excess nitrogen- short films for social media linking nitrogen and sustainable development goals
A good communication of complex environmental problems is essential to make a change. This communication should not only focus on policy makers, but also on citizens, as they are central for transformation processes....
An Integrated Approach to Nutrient Management on Dairy Farms
Animal production is criticised for excessive environmental impact. The dairy industry has improved nutrient efficiency through cow genetics and feeding but further improvements require an integrated farm approach that...
Relocation of pig productionin EU27 to reduce external N pollution costs
Why relocate? We test the hypothesis that relocation of pig production within the EU27 can reduce the external costs of nitrogen (N) pollution. For economic reasons, pig production is often concentrated in regions...
Evaluation of changes in landscape loading of total nitrogen to U.S. waters using monitoring results from the National Aquatic Resource Surveys
Uncertainty about how land use practices changes will quantitatively affect water quality and how long it will take to see improvements from management actions hinder efforts to reduce nitrogen (N) in streams. It is...
A national nitrogen target for Germany
The anthropogenic nitrogen cycle is characterized by a high complexity. Different reactive nitrogen species (NH3, NH4, NO, NO2, NO3 and N2O) are set free by a large variety of anthropogenic activities. At the same time...
Evaluation of nitrogen balance at different scale in Hokkaido dairy farming
New dairy system in Hokkaido, Japan [TMR system] • The farms which joining TMR (total mixed rations) systems grow (1)corn and grass on their fields. However, harvesting and utilization are done as a community basis. •...
1,2,3-Triazoles as Nitrification Inhibitors for Australian Soils
Nitrification is the multi-step oxidation of ammonium (NH4 +) to nitrate (NO3-). Nitrification inhibitors (NIs) can be used to reduce nitrogen losses from synthetic fertilisation application, by slowing the microbial...
Nitrapyrin helping farmers to get more value of slurry and increase silage production on dairy farms in italy and Germany
Slurry is always a byproduct in animal production. Historically farmers never perceived the value of slurry as a fertilizer as equal to mineral fertilizers. Using nitrogen stabilizers such as nitrapyrin helps farmers...
A nitrogen footprint tool (NFT) for communities: A case study in Baltimore, Maryland US
Nitrogen footprint tools (NFTs) allow entities to determine the amount of reactive nitrogen lost to the environment as a result of the entities resource use. The community NFT model estimates these loses for census...
Connecting soil nitrogen availability and crop yield for a greener agriculture
• The microbial conversion of nitrogen in agriculture is an undeniable challenge,since high rates of N are introduced into the soil (up to 120Tg per year) • Up to 70% of the introduced N is converted by...
Gridded Soil Surface Nitrogen Surplus on Agricultural Land: Impact of Land Use Maps
Nitrogen (N) compounds as plant nutrients play a key role in food production. Additional N nutrients, including mineral fertilizers, have been applied to agricultural land to an extent that impacts on the global N...
Assessment of nitrogen flows at farm and regional level when developing the manure management system for large-scale livestock enterprises
Priority environmental concern in livestock and poultry farming in Leningrad Region is manure utilisation on large-scale agricultural enterprises. The nitrogen flows on large-scale livestock enterprises in Leningrad...
Sensor technologies for detection of urine patches in livestock-grazed pastures
Urine patches in grazed Results pastures are hotspots for nitrogen (N) losses through leaching and nitrous oxide (N2O) emissions. A New Zealand designed ground-based sensing machine, Spikey®, can detect urine patches...
Buried traits in the rhizosphere: crop control of nitrification
Biological nitrification inhibitors (BNIs) in root exudates reduce nitrification rates [1]: •increasing N retention time in the root zone – mobility NH4+<<NO3-; •decreasing fertilizer need and the associated...
Citizen dialogue on policy instruments for the reduction of reactive nitrogen in Germany
The introduction into the topic of reactive nitrogen and the collection of ideas for mitigation was focus in the regional conference six volunteers were sent to the conference of delegates. There the most important...
Tree nutrition increasingly imbalanced in European forests
Element ratios in foliage are used to detect imbalances in tree mineral nutrition. Imbalances occur when the relative availability of nutrients is reduced. Despite emission reductions over the last 30 years, nitrogen...
High-resolution maps of ammonia concentration and nitrogen deposition for Baden-Württemberg
Maps of wet and dry deposition of reactive nitrogen (Nr) compounds are generated on a hectare raster for Baden-Württemberg (BW), Germany. An integrative modelling approach is applied, combining interpolation methods...
