• 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...

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...

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...

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...

•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...

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....

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...

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...

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...

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...

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. •...

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...

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...

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...

• 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...

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...

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...

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...

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...

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...

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...

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...
