APSIM has been used in a broad range of applications, including support for on-farm decision making, farming systems design for production or resource management objectives, assessment of the value of seasonal climate forecasting, analysis of supply chain issues in agribusiness activities, development of waste management guidelines, risk assessment for government policy making and as a guide to research and education activity. Potential reduction in crop productivity will be one of the biggest challenges. A new sunflower module was released in the Agricultural Production systems SIMulator - APSIM version.
Apsim modeling trial#
An example of model performance in a long-term cropping systems trial is provided. In Australia, APSIM-based modeling has been extensively used to investigate options for improving crop management and WUE in the dryland farming systems. Reports of APSIM testing in a diverse range of systems and environments are summarised.

These modules include a diverse range of crops, pastures and trees, soil processes including water balance, N and P transformations, soil pH, erosion and a full range of management controls. The paper outlines APSIM's structure and provides details of the concepts behind the different plant, soil and management modules. Mean ensemble model results showed reduced uncertainty for different crop parameter, especially the grain yield differences were reduced by 0.73-4.1 compared to observed yield. APSIM was developed to simulate biophysical process in farming systems, in particular where there is interest in the economic and ecological outcomes of management practice in the face of climatic risk. Sensitivity analysis of both models showed that grain yield in CERES-Wheat was more sensitive to field capacity and in APSIM grain yield was quite sensitive to nitrogen application rate. The Agricultural Production Systems Simulator (APSIM) is a modular modelling framework that has been developed by the Agricultural Production Systems Research Unit in Australia. Agricultural Production Systems Simulator (APSIM) is a modelling framework that allows individual modules of key components of the farming system (defined by.
