Online calculator measures consumers’ ‘nitrogen footprint’

Individuals can assess how their behaviour is affecting nitrogen pollution with a newly developed nitrogen footprint calculator, which was developed by a team from the University of Virginia (U.S.) and the Energy Research Centre (ECN, the Netherlands). For many people in wealthy countries, reducing protein consumption to the recommended levels and reducing the amount of red meat and energy they consume would significantly lower their nitrogen footprint.

Changes in European sulphur dioxide, nitrogen oxides and CO2 emissions since 1960

Emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) have fallen significantly across Europe since 1960. According to recent research, this is caused by a combination of factors including improved energy efficiency, a changing fuel mix and specific emission control measures. At the same time CO2 emissions have only increased moderately, mainly due to improvements in energy efficiency.

Increased fire frequency may cause long-term changes to soil carbon and nitrogen

Fire frequency is changing globally, yet it is unclear how such changes affect soil carbon and nitrogen storage, and, in turn, impact on ecosystem productivity. A study was conducted to evaluate how increased fire frequency drives changes in soil carbon and nitrogen over multiple decades. Data from 48 sites that have experienced altered fire frequency were analysed, spanning up to 65 years. The meta-analysis found that frequently burned sites experienced a significant decline in surface soil carbon and nitrogen over time — on average having 36% less carbon and 38% less nitrogen, after 64 years, than sites that were protected from fire. The researchers also observed comparable changes in an independent field dataset and in dynamic model simulations of global vegetation. The results indicate that future changes in fire frequency may lead to long-term changes in the amount of carbon and nitrogen stored in soils, especially in savanna grasslands and broadleaf forests. This has implications for the global carbon cycle and for ecosystem productivity and should, therefore, be considered in the design and implementation of relevant policy instruments.

Nitrogen pollution measures need tailoring to specific areas to ensure cost-effective results

New research has shown that policy measures in Denmark have successfully reduced total nitrogen loading to 10 estuaries by 39% in recent decades. However, to fully meet the targets of the EU Nitrates Directive and comply with the EU Water Framework Directive in a cost-effective manner, further mitigation measures must be tailored and focused to particular areas.

Agri-environment scheme cuts nitrogen pollution from beef farm in Ireland

Ireland's national agri-environment scheme can reduce nitrate leaching from beef farming, shows a recent study. Nitrate leached at an average rate of 17.3 kilograms per hectare (kg/ha) on studied plots which complied with the scheme. This compares with 63.1 kg/ha on intensively farmed plots. The programme can therefore help Ireland meet requirements of the EU’s Water Framework Directive (WFD) and Nitrates Directive, the researchers suggest.

Soil nitrogen increased through greater plant biodiversity

Increased plant biodiversity improves grassland soil quality by boosting its nitrogen levels, even in the absence of nitrogen-fixing plants, recent research has found. Previous research has shown that grasslands with higher biodiversity had higher levels of carbon and nitrogen. However, in the case of nitrogen it has been suggested that this was purely a result of increased numbers of nitrogen-fixing legumes, such as clover. This study was the first to show that, even without legumes, increased numbers of grassland species increased both carbon and nitrogen soil stocks.

Soil biodiversity reduces nitrogen pollution and improves crops’ nutrient uptake

Increased soil biodiversity can reduce nitrogen pollution, improve nutrient uptake by plants and even increase crop yields, new research suggests. The two-year study found that levels of nitrogen leaching from soil with an abundant soil life were nearly 25% lower than for soil with a reduced level of soil life. Practices which enhance soil biodiversity such as reduced tilling, crop rotation and organic farming may therefore help reduce the environmental impacts of fertilisers and improve agricultural sustainability, the researchers say.

Risks of biodiversity loss posed by nitrogen and phosphorus pollution in European freshwaters

The risk of eutrophication as a result of nitrogen and phosphorus pollution in Europe’s freshwaters fell by 22% in lakes and by 38% in rivers between 1985 and 2011, new research has shown. The researchers analysed data across 88 European river basins using a new statistical approach which could be used to help identify factors which increase eutrophication risks.

Measuring the impacts of the Nitrates Directive on nitrogen emissions

The EU's Nitrates Directive has led to significant decreases in nitrogen pollution in Europe, a new study suggests. Modelled scenarios with and without implementation of the Directive showed that it had resulted in a 16% reduction of nitrate leaching by 2008. These improvements could be further increased as implementation becomes stricter, the researchers conclude.

Reduced heavy metals and nitrogen in mosses reflect falling air pollution across Europe

Deposition of heavy metals and nitrogen is falling across Europe, a new study suggests. The researchers used the levels of these pollutants in mosses as indicators of how deposition has changed from 1990 to 2010. These reductions are likely to be the result of effective air pollution policies, they say.

Travelling slower reduces fuel consumption and nitrogen oxides emissions of ships

Ships that reduce their speed use less fuel, which lowers costs for shipping companies. The slow steaming practice also cuts nitrogen oxides (NOx) emissions. A study found that ships travelling on four European routes lowered their NOx emissions by 12% during the economic crisis of 2008/2009. Shipping continues to be a major way of transporting goods, however, and as the global economy recovers the researchers and civil society call for additional measures to reduce NOx emissions from shipping and improve air quality in Europe.

Monetising the biodiversity benefit of reducing nitrogen pollution in the air

Nitrogen deposited from the atmosphere is in decline in Western Europe due to targeted policies on emissions, with emissions 25% lower than their peak in 1990. Policy measures to lower nitrogen air pollution — which damages plant diversity, buildings and human health — have made an impact and are forecast to continue to lower nitrogen levels in the future, offering an opportunity to evaluate their impact. This study uses the UK as a case study to answer the policy question: what is the economic impact on biodiversity of forecast reductions in nitrogen pollution?

The Fall River Long-Term Site Productivity Study in Coastal Washington: Site Characteristics, Methods, and Biomass and Carbon and Nitrogen Stores Before and After Harvest

The Fall River research site in coastal Washington is an affiliate installation of the North American Long-Term Soil Productivity (LTSP) network, which constitutes one of the world's largest coordinated research programs addressing forest management impacts on sustained productivity. Overall goals of the Fall River study are to assess effects of biomass removals, soil compaction, tillage, and vegetation control on site properties and growth of planted Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Biomass-removal treatments included removal of commercial bole (BO), bole to 5-cm top diameter (BO5), total tree (TT), and total tree plus all legacy woody debris (TT+). Vegetation control (VC) effects were tested in BO, while soil compaction and compaction plus tillage were imposed in BO+VC treatment. All treatments were imposed in 1999. The preharvest stand contained similar amounts of carbon (C) above the mineral soil (292 Mg/ha) as within the mineral soil to 80- cm depth including roots (298 Mg/ha). Carbon stores above the mineral soil ordered by size were live trees (193 Mg/ha), old-growth logs (37 Mg/ha), forest floor (27 Mg/ha), old-growth stumps and snags (17 Mg/ha), coarse woody debris (11 Mg/ha), dead trees/snags (7 Mg/ha), and understory vegetation (0.1 Mg/ha). The mineral soil to 80-cm depth contained 248 Mg C/ha, and roots added 41 Mg/ha. Total nitrogen (N) in mineral soil and roots (13 349 kg/ha) was more than 10 times the N store above the mineral soil (1323 kg/ha). Postharvest C above mineral soil decreased to 129, 120, 63, and 50 Mg/ha in BO, BO5, TT, and TT+, respectively. Total N above the mineral soil decreased to 722, 747, 414, and 353 Mg/ha in BO, BO5, TT, and TT+, respectively. The ratio of total C above the mineral soil to total C within the mineral soil was markedly altered by biomass removal, but proportions of total N stores were reduced only 3 to 6 percent owing to the large soil N reservoir on site.

To compete with the increasing global food demand, it is necessary to increase the food production. Fertilizers which are in practice now a days has major disadvantage that 50% of nutrient contents loss due to leaching and also leads to ground water contamination. Slow release nitrogenous fertilizers are good in this regard in that they have minimum nutrient loss due to leaching. Potassium aluminum silicate (Leucite) nanoparticles occluded by calcium ammonium nitrates are slow release fertilizers and are synthesized by hydrothermal method. Its application as slow released nitrates fertilizers was determined by observing nitrate release for 16 days.

NAD+ biosynthesis in bacteria is controlled by global carbon/nitrogen levels via PII signaling [Microbiology]

NAD+ is a central metabolite participating in core metabolic redox reactions. The prokaryotic NAD synthetase enzyme NadE catalyzes the last step of NAD+ biosynthesis, converting nicotinic acid adenine dinucleotide (NaAD) to NAD+. Some members of the NadE family use l-glutamine as a nitrogen donor and are named NadEGln. Previous gene neighborhood analysis has indicated that the bacterial nadE gene is frequently clustered with the gene encoding the regulatory signal transduction protein PII, suggesting a functional relationship between these proteins in response to the nutritional status and the carbon/nitrogen ratio of the bacterial cell. Here, using affinity chromatography, bioinformatics analyses, NAD synthetase activity, and biolayer interferometry assays, we show that PII and NadEGln physically interact in vitro, that this complex relieves NadEGln negative feedback inhibition by NAD+. This mechanism is conserved in distantly related bacteria. Of note, the PII protein allosteric effector and cellular nitrogen level indicator 2-oxoglutarate (2-OG) inhibited the formation of the PII-NadEGln complex within a physiological range. These results indicate an interplay between the levels of ATP, ADP, 2-OG, PII-sensed glutamine, and NAD+, representing a metabolic hub that may balance the levels of core nitrogen and carbon metabolites. Our findings support the notion that PII proteins act as a dissociable regulatory subunit of NadEGln, thereby enabling the control of NAD+ biosynthesis according to the nutritional status of the bacterial cell.
