Abstract
ⶠWe hypothesized fractionating N losses are driven by land use in New Zealand. ⶠSoil δ15N was highest in cropping and dairy and lowest in indigenous systems. ⶠThere was a relatively strong correlation (Ï = â0.73) between δ15N and C/N. ⶠN balances showed that fractionating N losses increased with increasing land-use intensity. ⶠδ15N may be a useful tool in assessing potential N losses in different agronomic soils.
