The owners of the Organic Farm Company and BioFarm Products, James and Catherine Tait-Jamieson, took legal action against Brookfields Park Golf Club in 2002.
Mr Tait-Jamieson says since he filed court proceedings, 20,000 golf balls have been picked up from the 30 hectares of his property near the golf course.
"All inputs to an organic farm must be approved, and golf balls are not an approved input. The effect was that we couldn't make hay or silage in the paddocks surrounding the golf course."
He says he is relieved that the farm's future organic rating will now be safe.
