WFS - The "Dunkerry South" Trial
 

Downloadable Trial Results (MS Excel® spreadsheet)               Results and Technical Information (PDF format)

A farming systems trial has been established on David and Liz Hill’s property “Dunkerry South” at Nindigully, near St George, since 1996. The aims of the trial are to assess the effect of contrasting crop/crop and pasture/crop strategies on sustainable and profitable farming systems in the less than 600 millimetre, sub-tropical rainfall zone, and to involve growers and agribusiness in target setting, decision making and management of the trial.
The systems being studied are:      •   continuous winter cereal (wheat, barley)      •   grain legume - winter cereal rotation (chickpea - wheat)      •   opportunity cropping rotations with wheat, barley, chickpea,           faba bean, canola, grain sorghum, millet, mungbean and lab lab      •   short-term legume leys of medic and lucerne in rotation with           wheat      •   mixed pasture leys of Bambatsi Panic plus legume (medic and           lucerne ) in rotation with wheat.
