Aim of model: PERFECT was developed for cereal growing areas of the sub-tropics of Australia. It is a paddock scale model that predicts the effects of:
climate, soil type, crop sequence and fallow management
on the water balance, erosion, and productivity.
Target user group: Originally developed for research but is an extremely useful educational tool.
Type of model: A mechanistic model. The overall structure is physically based but individual processes may be represented by empirical relationships.
Regional target: Developed for sub-tropical grain growing areas of Queensland but the model has been successfully validated and applied in semi-arid areas of north Queensland and India.
Developed by: Mark Littleboy, David Freebairn, Mark Silburn, David Woodruff, and Graeme Hammer.
