During our years at Chaos Springs we have continually experimented and used a variety of plant extracts for managing the soils in our pastoral, orchard and market garden systems.This direction was initiated when we first purchased our farm in 2001. At that time we knew little about New Zealand flora or pastoral systems as we had been market gardening in Utah for 20 years.We were so excited about the farm we had just purchased covered in beautiful yellow flowers we never thought they would be a problem.  A week later when Jenny’s father Dennis arrived for a farm tour, I thought he was going to break into tears.  We tried to reassure Dennis that getting rid of ragwort and gorse would not be that difficult organically………………………………
