Productive Pastures Start Below the Surface!
EOI's have now opened for the 2026-27 DPIRD Soils - New Horizons program.
DPIRD’s Soils – New Horizons program is a Whole Farm Nutrient Mapping (WFNM) initiative that supports evidence-based fertiliser decision-making in high-rainfall pasture systems. This program is the latest evolution of DPIRD’s WFNM efforts, building on over 15
years of experience. It expands the approach across the entire >550 mm annual rainfall zone, excluding areas within the Healthy Estuaries WA priority catchments. WFNM aligns fertiliser use with pasture growth targets by using soil test data to optimise
nutrient application. This improves nutrient efficiency, supports profitable and sustainable pasture production, and reduces nutrient loss to waterways.
The WFNM process involves:
✓ Collecting representative soil samples from each paddock based on a standardised sampling methodology.
✓ Testing soil samples for phosphorus buffering index (PBI), phosphorus, potassium,
sulfur and pH.
✓ Comparing results against validated nationally agreed critical soil test values.
✓ Creating colour-coded nutrient maps and tables to guide fertiliser application
✓ Using the nutrient and lime calculator tools and agronomic advice to develop fertiliser
action plans.
✓ Ensuring accurate and even nutrient delivery, following the 4Rs of fertiliser
management.
✓ Growing pasture sustainably and economically.
The WFNM process has been assessed and approved as an interpretation system under
Fertcare®.
If you would like to be involved in the Soils - New Horizons program, simply scan the QR code below or follow the link provided and register your EOI, alternatively you can email Bridgetown-Greenbushes Community Landcare at [email protected] for further information.
