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 ...

Fertiliser tax of €0.05–0.27 per kilogram calculated for France as incentive to limit its use
Farmers seeking to make the most of high crop prices may increase the area of land farmed with a valuable crop and also apply more fertiliser. These two changes can have negative environmental effects, such as water pollution caused by nitrogen run-off, biodiversity loss due to land-use change, air pollution from fertiliser and the release of greenhouse gases through changes in land use. In the ...

Advancing agricultural adaptation and mitigation
This policy brief, published by Science, examines how agricultural science can help improve policies for climate change adaptation and mitigation. Global food production must rise to meet global food needs, but predicted increases in extreme weather events — combined with stresses such as poverty, conflict and weak governance — threaten food security. At the same time, agricultural ...

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 ...

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 ...
