L'augmentation des niveaux de pollution dans les années 1980 a conduit à l'introduction, au début des années 1990, d'une législation pour les contrôler. Cette législation fut complétée par des codes de bonne pratiques agricoles. Une bonne pr

Nitrate leaching losses from intensively managed monoculture grass and grass-clover pastures were measured during 1994-96 at a long-term experimental farm in south-west Scotland. Field-size lysimeter plots were established in 1993 on the existing pas

The recovery and utilization of heat energy from the aerobic treatment of slurry to remove odour and BOD5 is being investigated. An earation unit with heat recovery has been built for a piggery, housing 300 fattening pigs and 100 weaners. A series of
