Di Haggerty operates a 12000-hectare sheep and cereal property in Western Australia’s central Wheatbelt using animals, worm liquid, compost extract and low levels of nitrogen. Di farms with her husband Ian and son James. The recent Charles Massy book “Call of the Reed Warbler” writes that the Haggertys are two of the most radical and open-minded thinkers in world agriculture. They are not just healing, but also transforming the earth because they are working with and not against Mother Nature”.
