However, it is important to
note that at the highest annual N application rate of 400 kg Nha1,
which is double the recommended best practice rate, split N
fertiliser applications on top of a urine patch increased the total
NO3
leaching loss (i.e. from non-fertiliser N sources). We
confirmed the second hypothesis, that leaching would be greatest
under an autumn deposited urine patch when compared to a
spring deposited urine patch. The results of this study indicate that
best practice fertiliser management (i.e. fertiliser applied at
