Soil mapping for smarter farming
and a healthier environment
The Waiau catchment – covering Te Anau Basin, Orauea and Lower Waiau – is home to a community-led soil mapping project in partnership with Land and Water Science.
With guidance from a 12-member committee representing our three local Catchment Groups, this project aims to improve the accuracy of soil data through high-resolution maps that reflect the unique variability of our land.
We all rely on local knowledge and experience, and while this approach works well, existing soil maps are too coarse to support precise property or paddock-scale management. As modern farming is increasingly dependent on detailed soil information, there is a clear need for updated soil maps that can better reflect land variability.
The project has four phases, and we're currently working on Phases 1 and 2. We are integrating all the existing data to create preliminary soil maps and then ground-truthing those maps with 100 soil pits across the catchment. Land and Water Science will then create the high-resolution soil maps.
These maps will give farmers access to actionable, practical, paddock-scale insights to:
optimise fertiliser application
improve soil health
enhance farm productivity
create environmental sustainability.
