Premium Compost

Biomix produces a mature compost product. All of Biomix compost products are produced to meet the Australian Standards (AS4454) for compost.


Premium Blended Compost

Biomix conducts free soil tests to determine if a compost blended with lime or gypsum would suit your individual soil types.



Similar to the vineyards, orchards are seeing the benefits of applying Biomix compost. The compost reduces water use, decreases soil fluctuations and improves overall results.



Biomix compost is widely used by wineries throughout Victoria. By using our compost on the vines it reduces water use and prevents weed growth.


Broad Acre

Biomix compost is used by broad acre farmers to improve soil structure, reduce water use and increase plant yield. Biomix compost can be blended with lime and gypsum to meet specific soil needs.


Vegetable Growers

Biomix compost is used by vegetable growers between crop rotations. The compost replaces organics lost during the harvest and provides a boost to improve growth and yield.
