Abstract

The results of a two-year lysimeter investigation into the effects of fertiliser nitrogen (N) combined with pig or cattle slurry applied in winter or early spring on nitrate (NO3-N) leaching are presented. Soil type, fertiliser N and a combination of fertiliser plus slurry N affected concentrations of NO3-N in the drainage water. Peak concentrations were recorded usually in the December-February period. In the drainage water the maximum admissible concentration (MAC) of NO33-N for drinking water was breached to the greatest degree by pig slurry (Year 2) applied in November (117 kg per hectare) combined with fertiliser N (300 kg per hectare).
