Abstract
Water balance simulation techniques were used to evaluate three cropping systems under a range of soil-climate environments. The systems were assessed on economic and conservation grounds using crop yield and surface run-off estimates. A soil water balance model was developed and tested for the study region - the Darling Downs in southern Queensland. The model explained 87-96% of the observed variation in stored soil water in test runs. Relationships between grain yield and an index of crop water supply were established which explained 76% of the observed variation in wheat and sorghum farm yields. These relationships were used to derive yield estimates of simulated crops under two conventional cropping systems - continuous wheat and continuous sorghum - and a more flexible system, opportunity cropping
