Nitrogen fertiliser research plan

While the benefits of nitrogen fertilisers in improving crop yields have long been appreciated, a new study will look at ways of ensuring that it used to greatest efficiency in Scotland while minimising any damaging emissions.

The first phase of the research – backed by a £30,000 Scottish Government grant – will see the SRUC and the Centre for Ecology investigate which areas need to be targeted to minimise the release of greenhouse gases such as nitrous oxide and of nitrate pollution into waterways Commenting on the benchmarking work which will be used to set targets for future reductions in emission levels, rural affairs minister Mairi Gougeon said the Scottish Government wanted famers to move towards a more profitable, low-carbon future, while still ensuring business viability for future generations. “That is why I am establishing research into the feasibility of reducing Scotland’s emissions from nitrogen fertiliser,” she said.

While acknowledging that nitrogen was a key component in ensuring the sustainability of the country’s food production, she continued: “When applied in an inefficient manner, it can serve as a source of pollution, through either greenhouse gas emissions or impacts on air and water quality.”

Nitrogen use efficiency had been included as an element in the administration’s climate change plan, said Gougeon – and as a result the government was committed to continuing to provide advice, information and technical assistance through the likes of the Farm Advisory Service, the Soil Nutrient Network and Farming and Water Scotland.

“I hope that this new research will help to further develop our knowledge and understanding of nitrogen fertilisers to enable us to better support our plant and natural environment,” she added.
