Introduction – Biosolids application Biosolids: Organic waste products from sewage & wastewater Beneficial uses: Contains nitrogen, phosphorous and organic matter Fertiliser for soil remediation, lawns, gardens, public land, agriculture & forestry Safety: Ensure no environmental harm is caused by its use, including by the potential ...
Alongside the Climate Change Committee’s focus, there is still much more to be done, most notably to reduce the use of nitrogen fertilisers and pesticides, and support farmers to adopt agroecological and organic systems. The EU’s recent Farm2Fork and biodiversity strategies set the ambitious target that 25% of land is under organic by 2030, with a 50% ...
If we cut grain-fed meat from our diets, we could free up 50% of cropland and phase out 80% of nitrogen fertiliser use. As our recent Fixing Nitrogen report revealed, excess nitrogen has a huge impact on our rivers and wildflowers and drives nitrous oxide emissions, a greenhouse gas more long-lived than methane. ...
SUMMARY Odour pollution is a recurring source of complaint. Incidents related to olfactory pollution can cause physical discomfort in people. Although some emissions come from natural sources, others are related to specific industries or processes. Establishing an early-warning perimeter system, based on sensors, for leaks and diffuse emissions can help to reduce odoriferous pollution episodes. ...
The intention was to demonstrate that soil quality characteristics would either be enhanced, or at least maintained, through the use of green manure crops and that soil nitrogen levels could be enhanced. Organic horticulture practiced on this farm relies on the development of healthy fertile soils through the use of soil building crops of legumes, green manures, sound rotations ...
We have previously discussed soil degradation and now turn our attention to agricultural waste and pollution. As the population of the world increases so does the demand for food. This in turn leads to pressure on those in the agricultural sector to increase yields whilst doing so at affordable pricing. This has caused farmers to abandon traditional methods in favour of the intensive farming we ...
Storage duration has a large impact on GWP, while amount of chemical nitrogen fertiliser substituted has a large impact on primary energy use. ...
This is mainly caused by a high concentration of nitrogen in the substrate. Nitrogen in the manure is converted into ammonia which inhibits the formation of biogas already in low concentrations. ...
The Agricultural phase results to be the process that produces the highest GHG emissions, mainly because of the production and the use of nitrogen fertiliser.Keywords: GHG emissions, greenhouse gases, LCA, life cycle analysis, rapeseed biodiesel, biofuels, biodiesel production, biodiesel consumption, EU, European Union, environmental impact, agriculture, nitrogen ...
Anthropogenic nitrogen loading, particularly fertiliser usage in agricultural soils is thought to be a potentially important source of nitrous oxide (N2O) emission, which can be controlled by properly managed fertiliser usage. ...
European farmers are currently affected by an increase in the price of fertilisers (from an index of 100 in 2005 to 150 in 2012 after it peaked at almost 200 at the end of 2008) that calls into question the future availability of these kinds of inputs. ...
Meet Didymo. Didymo, or Didymosphenia Geminata as it’s known scientifically, is a microscopic algae plaguing rivers around the globe. It produces thick, mat-like growths or blooms that coat stream beds and rocks in both flowing and still rivers. The slime, which is flourishing more and more every day, is caused by a microscopic alga, a diatom that hasbecome so notorious it is recognised ...
Some of carbon taken up by phytoplankton will sink to the deep ocean, providing sequestration of carbon in the deep ocean. This paper considers nitrogen as the added nutrient and determines the losses in this sequestration process, taking into account a number of mechanisms. ...
Across Africa, for example, agriculture that removes soil nutrients such as nitrogen, potassium and phosphorus without replenishing them (sometimes termed nutrient mining) contributes to low crop productivity. ...
High-yielding crop strains, irrigation, fertilisers and pesticides were brought into developing countries, including India and the Philippines, increasing yields by more than 250 per cent, and pulling over a billion people back from the brink of starvation. ...
Three sections along the mainstream of the Yellow River were chosen as sites for monitoring the concentration variations of nitrogen species. First, the nitrogen in the water was mainly dissolved and dominated by nitrate–nitrogen. ...
The Twinwoods AD plant produces 30,000 tonnes of a nutrient-rich liquid bio-fertiliser per annum that can be used back to grow more arable crops. This replaces the need for bought-in manufactured nitrogen fertilisers for the 600Ha arable farm. ...
The resulting treated sewage is then used as nitrogen-rich organic fertiliser for agriculture."There is no shortage of outlets - the farmers love it," said Site Process Controller, Phil Smith. ...
We found that leaf ascorbic acid content is strongly influenced by both maturity and soil nutrition, with leaves of seven week old matured plants having the highest content. β-carotene increased with increasing amount of soil nitrogen and with increasing plant age. The loss of both visual and nutritional quality during storage was influenced more by maturity at harvest and the ...
SCIENTISTS at an environmental biotechnology company have developed a biological product that could potentially be used to directly reduce the amount of nitrogen and other fertilisers used by arable farmers. Amnite® A100, created by Stockton-on-Tees-based CBio (Cleveland Biotech), relies on an improved symbiotic relationship between plants and soil ...
