Matured compost for broadacre systems that improves structure, retains moisture, and supports nutrient efficiency — especially after drought or hardpan stress.

Why Use Compost in Broadacre?

In cropping, fertiliser efficiency is only as good as your soil's ability to hold it. If you're dealing with soil fatigue, poor infiltration or yield plateaus, it's time to think beyond NPK. Biomix builds your soil capital so every input works harder — especially through dry spells.

We work with cereal and oilseed growers across Victoria, helping improve structure, microbial activity and carbon levels without compromising your schedule or margins.

Boosts moisture retention in light and loamy soils
Improves nutrient uptake and microbial balance
Reduces input losses from leaching or runoff
Helps alleviate compaction after heavy machinery use
Builds resilience after drought or stubble-burn years

“We cut our synthetic N back 25% and saw no yield loss after conditioning with compost. The soil holds water better and crops get out of the ground faster.”

Case Study

Broadacre Cropping – Shepparton, VIC

Farm Type: Mixed cereal cropping (wheat, barley)

Area Treated: 65 hectares

Application Rate: 10 t/ha Biomix Compost

Application Timing: Post-harvest, early autumn

Challenge:

After consecutive dry years and heavy synthetic input use, the farmer reported poor soil tilth, hardpan compaction, and inconsistent moisture retention.

Solution:

Biomix compost was applied to improve soil structure, water infiltration and biological activity. Compost was spread in early autumn and lightly incorporated.

Outcomes:

Improved topsoil structure by harvest (friability and aggregation noted)
Organic Carbon increased from 0.9% to 1.4% over 12 months (lab tested)
Fertiliser use reduced by 20% the following season
ROI: Achieved breakeven on compost within first year via fertiliser savings and improved grain yield (4.6 t/ha vs 3.9 t/ha previous year)
