Nitrate leaching from dairy farming

Nitrate leaching from dairy farming - effect of grassland composition and frequency in crop rotation.

In nitrate vulnerable zones with agricultural production organic dairy farming may present an opportunity to reduce nitrate leaching if grassland N is efficiently utilised. The overall objective of the proposed project is to optimise N management in organic dairy farming. The work includes determination of precrop effect and nitrate leaching following ploughing of grassland as affected by grassland frequency in the crop rotation and with comparison between grass-clover and fertilised pure ryegrass.
