Optimising benefits of vermiculture in commercial-scale vegetable farms
Earthworms are known to be an indicator of healthy soil function. However, there has been limited research into how commercial vegetable farming practices impact on earthworm activity levels and how earthworms can potentially contribute to farm productivity.
Conducted from 2016 to 2019, this project aimed to investigate and promote the benefits of increased earthworm activity for commercial vegetable farms. The research included:
- A literature review of the potential benefits of earthworm activity in commercial vegetable growing, and the factors that affect earthworm populations and activity
- Detailed field research carried out at two sites in Victoria and Tasmania, with a further 16 demonstration sites across Australia
- An economic assessment of the possible productivity benefits of farm practice changes that increase earthworm activity.
