APSIM: The Leading Software Framework for Agricultural Systems Modelling and Simulation

The Agricultural Production Systems sIMulator (APSIM) is internationally recognised as a highly advanced platform for modelling and simulation of agricultural systems. It contains a suite of modules that enable the simulation of systems for a diverse range of plant, animal, soil, climate and management interactions. APSIM is undergoing continual development, with new capability being added to APSIM Next Generation. Its development and maintenance is underpinned by rigorous science and software engineering standards. The APSIM Initiative was established in 2007 to promote the development and use of the science modules and infrastructure software of APSIM. The current members are CSIRO, The State of Queensland, The University of Queensland, AgResearch Ltd. (NZ), University of Southern Queensland, Iowa State University, (US) and Plant and Food Research (NZ)
