Revive turf and pasture by breaking down thatch.

Healthy pasture and turf can be inhibited by the build-up of browntop and other thatch over time.

Biostart ThatchBusta is a blend of fermentation extracts that stimulates the decomposition of thatch. A biological dethatcher, ThatchBusta activates naturally occurring decomposition microbes to breakdown thatch and release its nutrients back into the soil.

Use ThatchBusta to:

  • Break down browntop thatch

  • Activate decomposition microbes

  • Improve soil structure

  • Improve moisture penetration

  • Stimulate clover growth

  • Improve pasture quality

  • Improve nutrient mineralisation

Breaking down browntop thatch allows white clover seeds to germinate, which leads to increased clover content in your pasture, thereby improving pasture quality and animal performance.
