Goals & Objectives 


The N2O programme focuses on manipulating some of the N inputs that drive the quantity of N2O released and on manipulating the processes that form and release N2O. 


Manipulating N inputs investigates ways to reduce N inputs through plant breeding/selection and plant management (Objective 2.1). Manipulating processes will address the challenge of optimising nitrification inhibitors so that their effectiveness and longevity is increased (Objective 2.2). Research will also be undertaken to determine the impact of soil amendments on the denitrification process and the N2O/N2 ratio (Objectives 2.3). Finally, the programme will investigate ways to mitigate N2O emissions through better understanding its relationship with soil physical characteristics and soil water status (Objective 2.4).
