Nowadays, Australia is the fourth leading wheat exporting in the world wheat market. In 2005-6, Australia exported 16 million tonnes of wheat to the world which earned around $A 3.54 billion of foreign exchanges for the nation. Most grain in Australia is harvested at lower moisture content than safe storage moisture. As grain dries in the field, losses due to natural shedding and lodging increase. Furthermore, a summer rainfall pattern prevails and causes weather damage when the crop is ripe but not yet harvested. For instance, the losses of sprouting due to rainfall are at least $30-40 million per year across Australia. Therefore wheat harvest represents a period of high risk and is also a bottleneck in wheat production in Australia. This study aims to develop and apply a Grain Harvest Simulation Model as a potential tool to quantify and test the various management options to effectively manage the risks associated with weather damage at harvesting time. The overall aim of the study is to maximize the economic returns to growers, through maximizing the quality and quantity of delivered grain whilst minimizing annual and long-term financial risks associated with weather damage.
