Granular soil foundations and soluble seasonal programs for broad-acre production.
Build a crop programMETRAHUM STRATEGY
Build a granular foundation before planting, then use targeted soluble products around establishment and active growth.

→SEASON LOGIC
A practical three-stage starting point.
Soil preparation
Use SOIL-G or Humate NPK Granule where mechanical spreading is required.
Establishment
Position WSG Core or WSG NK 6-0-10 in the early irrigation program.
Seasonal follow-up
Use K18 or validated biological WSGs according to crop stage and analysis.
BEFORE APPLICATION
Measure first. Dose second.
- Calibrate dry spreaders before full-field use
- Balance nutrient-enhanced products against the complete fertiliser plan
- Use biological products only within their validated protocol
