The overall objective of the project was to develop practical slurry application timing strategies to minimise nitrogen (N) losses to the air and water environments. Replicated field scale experiments were carried out on commercial farms covering a range of livestock and cropping systems, soil and climatic conditions. Ammonia, nitrous oxide and nitrate leaching losses were measured from contrasting improved technology slurry (bandspread/shallow injection) application timings. The effects of the contrasting application timing strategies on different N loss pathways (i.e. N ‘pollution swapping’) were quantified.
