Description

Soil Vulnerability Modelling, formerly known as EnSus, is a framework for analysing the environmental risk associated with land use pressure on the land and deriving best land management practices that will help mitigate these risks. This model can help provide a basis for confident policy development and farm management.

Purpose

Soil Vulnerability Modelling defines soil zones of similar vulnerability profile for nutrient and microbial contamination to waterways to provide a basis for: 1) setting nutrient load limits across a catchment 2) target management of non-point-source discharges 3) setting aside vegetated buffer zones to trap contaminants in overland flow.
