Some farmers in the central west of New South Wales have used a new fertiliser to help deal with what's been called the worst drought in living memory.
It is human sewage, treated and dewatered to produce biosolids, an organic fertiliser transforming about 30 farms in the region.
From more than 20 metropolitan treatment plants, Sydney Water is producing about 180,000 tonnes of biosolid fertiliser a year.
About 70 per cent goes directly to farms such as Ulabri, a 900 hectare grazing enterprise at Wattle Flats near Bathurst owned by Gordon and Linda Nash.
