Not AvailabletResource shortages, driven by climatic, institutional and social changes in many regions of Asia,combined with growing imperatives to increase food production whilst ensuring environmental sus-tainability, are driving research into modified agricultural practices. Well-tested cropping systemsmodels that capture interactions between soil water and nutrient dynamics, crop growth, climateand farmer management can assist in the evaluation of such new agricultural practices. One suchcropping systems model is the Agricultural Production Systems Simulator (APSIM). We evaluatedAPSIM’s ability to simulate the performance of cropping systems in Asia from several perspec-tives: crop phenology, production, water use, soil dynamics (water and organic carbon) and cropCO2response, as well as its ability to simulate cropping sequences without reset of soil vari-ables. The evaluation was conducted over a diverse range of environments (12 countries, numeroussoils), crops and management practices throughout the region. APSIM’s performance was statistically.Not Availabl
