Fertiliser taxation and regulation of nonpoint water pollution: a critical analysis based on European experiences
In Europe, the effectiveness of current forms of control of nonpoint nitrogen pollution is considered to be weak. This assessment highlights the need to introduce more efficient modes of regulation. Many economists recommend a simple tax based on known polluting factors, for example a tax on purchases of mineral fertilisers. In addition to its simplicity of application and low information cost, ...

Likely impacts of biofuel expansion on Midwest land and water resources
US ethanol production should exceed 12 billion gallons by 2010, and EISA 2007 mandates 36 billion gallons by 2022, diverting one-third of corn to ethanol and 13% of soybean production to biodiesel. Increased demand will ricochet through other agricultural sectors and alter production patterns and land use in the Corn Belt. This paper discusses effects of biofuel expansion on land and water ...

Influence of maturity at harvest, N fertiliser and postharvest storage on dry matter, ascorbic acid and β-carotene contents of vegetable amaranth (Amaranthus hypochondriacus)
Vegetable amaranth is a leafy vegetable traditionally grown in sub-Saharan Africa and Asia where it is the most consumed traditional vegetable. It is considered to have high nutritional quality, containing relatively large amounts of vitamins A and C. We have assessed the influence of the maturity of the vegetable and soil nutrition on the visual and nutritional quality of amaranth. We found that ...

Two Cases of Misleading Environmental Declarations Due to System Boundary Choices
Abstract Environmental Product Declarations (EPDs) on electricity and nitrogen fertiliser are used to illustrate how a declaration or labelling* based on data from the current supply chain can be misleading when the production capacity in the supply chain is constrained. Three ways of avoiding such misleading declarations are suggested. Introduction: The cause of deception As a specific ...

Reduce Fertilizer and Nitrogen Input
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 microbes - by increasing and improving ...

Analysis of price volatility of mineral fertilisers: possible issues for European farmers
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. Since 2007, the strong demand from emerging countries, geopolitical tensions over natural resources, and the rise in the price of energy have been ...

Farmers Can Now Reduce Their Nitrogen Inputs and Maintain Yields
Cbio develops biological product which could potentially reduce nitrogen use in farming, increase yields and improve water quality. 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 ...

Considerations on the importance of nutrition habits for the national nitrogen balance of Austria
The anthropogenic nitrogen turnover of Western societies is highly unbalanced. As a consequence, a permanent supply of nitrogen via mineral fertiliser (produced with high energy inputs) and/or imported fodder are required and result in significant impacts of nitrogen emissions on the environment (air, water, soil). Key factors to an improved nitrogen balance on a national scale are the nutrition ...

Efficiency of carbon sequestration by added reactive nitrogen in ocean fertilisation
Addition of limiting nutrients to the surface waters of the deep ocean will lead to increased photosynthesis and associated biological productivity. 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 ...

Participative modelling to help collective decision-making in water allocation and nitrogen pollution: application to the case of the Aveyron-Lere Basin
The aim of this study is to develop simplified tools and methods in collaboration with local stakeholders to facilitate collective decision-making. The project is based on a series of experiments carried out between farmers and environmental officers and researchers (Aquae Project)1 on the Aveyron-Lere catchment area. Within this framework, a model of the catchment area was constructed to examine ...

Boris Johnson sets out his ten-point green plan
Where are food and farming in the ten-point green plan? Along with colleagues across the environmental movement, I have been anticipating Boris Johnson’s Green Speech today, where he set out a 10-point plan for how the UK will meet Net-Zero. All eyes were on the landmark new commitment to bring forward the ban on petrol and diesel car sales to 2030. But where were food and farming? If we ...

Agriculture and Environment in EU-15 — the IRENA Indicator Report
Background and purpose The IRENA operation (Indicator Reporting on the Integration of Environmental Concerns into Agriculture Policy) is a joint exercise between several Commission directorates-generals (DG Agriculture and Rural Development, DG Environment, Eurostat and DG Joint Research Centre, and the European Environment Agency (EEA) to develop agri-environmental indicators for monitoring the ...

Shocking Truth About Modern Agricultural Waste and Pollution
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 ...

Reduction of ammonia emissions during composting by Uncoupling of oxygen demand and heat removal
Intensive pig production systems result in high emissions of ammonia, odour and greenhouse-gases (methane and laughing gas) by exhaust ventilation air. Moreover, large amounts of manure (faeces and urine) are produced with insufficient nearby land for applications (Imbeath, 1998). These outputs lead to environmental problems related to acidification and euthrofication of natural ecosystems, ...

Observing the nitrogen cycle in a green manure trial on an organic farm
As part of a 5 year Federal Government funded Landcare project in the Gippsland area of Victoria, a number of on-farm trials have taken place. One of these trials was monitoring a range of green manures on a certified organic vegetable farm. The demonstration trialled and compared 6 different green manure crops each year for 3 years against a control. The control was immediately adjacent to the ...

Unlocking the potential of poultry manure
The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been referred ...

Farmers fine-tune research, spread their own innovations
Smallholder farmers can aid the uptake of research fruits and drive grassroots innovations. Joel Winston reports. The 1960s' Green Revolution demonstrated how technological innovations can transform agriculture. 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 ...
