Nature of the problem Th e transfer of nitrogen by either farm management activities or natural processes (through the atmosphere and the hydrological net• work) can feed into the N cascade and lead to indirect and unexpected reactive nitrogen emissions. Th is transfer can lead to large N deposition rates and impacts to sensitive ecosystems. It can also promote further N • 2 O emission in areas where conditions are more favourable for denitrifi cation. In rural landscapes, the relevant scale is the scale where N is managed by farm activities and where environmental measures are • applied.
