GM rapeseed could reduce fertiliser usage
Nitrogen fertiliser used in crop production is a substantial source of environmental pollution, contributing to around one third of the total greenhouse gas emissions from the world's agricultural sector. Recent research on a genetically modified (GM) variety of rapeseed, which has been made more nitrogen-efficient, suggests that yields comparable with conventional varieties can be obtained using ...

Soaring prices and climate change expose fertilisers as environmentally unsustainable
As oil and gas prices rise so does the price of artificial chemical fertilisers - the lynch-pin of industrial agriculture’s claims to be ‘efficient’. In the UK, the price of nitrogen fertiliser has doubled over the past year to around £330 per tonne. With oil currently at over $130 a barrel and with OPEC warning it could reach $200 by the end of the year, it has been suggested that fertilisers ...

Rising CO2 robs crops of protein
New analysis suggests that rising CO2 levels will affect the protein content of major food crops, and indeed this may already be taking place. Experts suggest this change in the composition of the foods we eat could have consequences for human nutrition. Farmers can limit these effects by using more nitrogen-based fertilisers, but these in turn have a high environmental cost. Research ...

Nitrogen fertilizer works way into sea and destroys marine habitats - EC
Substantial increases in the flow of nitrogen into the sea have raised concerns about marine pollution. New research shows that commercial fishing is playing an important, but now declining, role in transferring this nitrogen back onto land. Enormous amounts of nitrogen fertilizer are applied to agricultural land to increase crop productivity. However, the use of such fertilisers can be damaging ...

Perennial grass crops - a carbon neutral biofuel?
Perennial crops, such as grasses, are attracting increasing interest as potential biofuel crops. Perennial crops have significant advantages over many annual crops because they require less energy input during growth than annual crops which not only need to be planted each year, but typically require more fertiliser, herbicide and pesticide input. Research on farm-scale cultivation of the ...

Carbon credits to be used to fund GM food crops
US biotech firm Arcadia Biosciences has announced a plan to help fund the planting of genetically modified rice with carbon credits. The company will work with the Chinese government to give farmers who plant their crops carbon credits, which they can then sell on the global carbon trading market. Arcadia is touting its GM rice as a greener alternative to the regular crop. The plant has had a ...

America`s Emerging Bioeconomy
AMES, Iowa, August 30, 2007 (ENS) - Robert Anex wants to know what would happen if the increasing demand for ethanol prompts American farmers to decide against crop rotation and plant corn on the same fields, year after year. This spring farmers responded to the ethanol industry's demand for grain by increasing their corn acreage by 19 percent over last year, according to U.S. Department of ...

New Fertilizer Rule Protects Florida`s Liquid Heart
TALAHASSEE, Florida, August 30, 2007 (ENS) - The Florida Department of Agriculture and Consumer Services today adopted a final rule limiting the phosphorus and nitrogen content in fertilizers for urban turf and lawns. The Urban Turf Fertilizer Rule will reduce the amount of nitrogen and phosphorus applied in urban areas, limiting the amount of those compounds reaching Florida waters , including ...

IPPC guidance on ammonia, acids and fertilisers
Detailed EU guidance has been agreed on how to apply best available techniques (BAT) to minimise the environmental impacts of installations producing ammonia, acids and inorganic fertilisers. The BAT reference document, known as a bref, is of much more greater significance for the European industry than related IPPC guidance on specific inorganic chemicals (EED 09/01/07) as it targets chemicals ...
