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. I.15 Nitrate leaching from dairy
