DAISY to save on nitrogen in farming
Researchers from PLEN contribute with the mathematical model DAISY in a new government funded project that makes it possible to save significantly on the use of nitrogen in farming.
Researchers from PLEN contribute with the mathematical model DAISY in a new GUDP project that makes it possible to save significantly on the use of nitrogen in farming.
Lars Stoumann Jensen and his group is part of the new project StyrN, which is supported by the Ministry of Environment and Food. SEGES is the project leader and Department of Plant and Environmental Studies contributes with among others the mathematical model DAISY. DAISY is a dynamic nitrogen model meant to calculate the washout of nitrogen and changes in the organically bound nitrogen in the soil within a wide spectrum of climate, soil and farm types.
”A couple of years ago the EU Nitrogen Expert Panel, which I am a member of, proposed that environmental regulations of agriculture to a much larger extent should be based on nutrient balance accounting to prove their use efficiency. I am therefore very happy that the StyrN project will allow us to develop and test these monitoring tools together with SEGES and the farmers,” says Lars Stoumann Jensen, project lead for the KU part of StyrN.
StyrN is expected to lead to 1000 ton reductions of nitrate leaching, decrease greenhouse-gas emissions with almost 10.000 tons CO2-eq and reduce farmers’ economic costs g 18 mio. kr.
