We can all help in a response to our climate change fears with multi-benefits from diverting food waste from landfill, sequestering more carbon in soil, which improves soil fertility and the organic matter that helps retain soil moisture, which helps grow more plants, that sequesters more carbon and grows us healthier food! What's not to like?
We can all be doing some scale of worm farming in backyards, on back decks or balconies or contributing appropriate food scraps to a community worm farm or commercial operation. Then we get the opportunity to use the end products of vermicast, worm wee or vermisolution to improve the health of soils and plants.
I have stories to share of working with Brown Earth some years ago to help market their vermisolution product, Wormtastic. It was such an effective growth stimulant: more resilient lawns and plantings on golf course greens and council parks; longer roots and bigger garlic bulbs; longer flowering stems with more flower buds. But it wasn't a viable business because of the costs of trucking large amounts of this liquid product. How much more cost-effective to be able to make and apply this on-site i.e. multiples of localised scaled-to-suit production and application.
What right do we have to complain about our dry soils and water restrictions and increased bush fire risks if we're not doing our part to help restore degraded and dehydrated soil. The sum of the parts played by many contributors to environmental solutions can become a significantly positive outcome.
I have compiled a summary from the book by David Murphy (2005) "Organic growing with worms: A handbook for a better environment" of how to use the castings from a worm farm, as castings themselves and to make a vermisolution. Contact me if you would like a copy (for a donation to Binnowee Community Garden) or would simply like to talk about shared environmental concerns and interests.
