Whitiwhiti Ora - Biophysical susceptibility to nitrogen (N) leaching and runoff
-
Susceptibility to nutrient loss.
The dataset - what is it?
The layer shows the biophysical risk of leaching and runoff. The susceptibility was based on tracing Nitrogen loss from simulated urine patches using the Agricultural Production Systems Simulator (APSIM) model.
Why it's important
Provides the landowner with a high-level view of the susceptibility of leaching and runoff.

Caveats
The modelling is preliminary and uses coarse scale climate and soil data. It assumes that the simulated loses from a urine patch under pasture are representative of any actual land use
