Eucalyptus Model

A model for Eucalyptus plantations has been released in APSIM Next Generation. The current version of the model is suitable for sub-tropical genotypes (e.g. Eucalyptus grandis, E. urophylla, E. saligna, and their hybrids) grown in temperate to tropical environments, as it has been validated and tested on data from multiple sites in Australia and Brazil. This model is suitable for broad-scale industrial plantations, but with further calibration and testing could be suitable for different management settings (e.g. agroforestry applications), or for different genotypes (e.g. temperate plantation genotypes). Examples provided include N-fertilising, irrigation, weeds, harvesting and replanting. The APSIM framework provides a flexible basis on which to further develop this model for both commercial and non-commercial applications. For commercial access, please email apsim@csiro.au

APSIM Training - 20th and 21st February 2019

The next APSIM Training Workshop will be held in Brisbane on the 20th and 21st of February. 

The 2 day course is aimed at providing training in the use of the Agricultural Production Systems sIMulator (APSIM) focusing on the user interface. It is very 'hands on' with a mix of short presentations and tutorials relevant to research activities.

The course has been designed for both beginners and more advanced users who have developed simulations and require specific technical assistance. It will focus on individual needs with tutors providing one-on-one assistance. Common issues will be summarised and presented as more formal group tutorials.

The course will be limited to a maximum of 12 participants and can be tailored to meet specific needs of individuals and groups. A minimum of 10 participants will be required to run the course.

COURSE REQUIREMENTS

To successfully undertake this course you will need to have:

  • A Laptop PC:
  • A licensed copy of APSIM version 7.10 installed on the laptop;
  • For advanced users, current simulations you are working on, or background data for building simulations;
  • Organised all travel and accommodation associated with your training.

If you would like to register or have any questions, please email apsim@csiro.au

A simple demonstration of connecting APSIM to optimisation techniques

The APSIM Initiative Reference Panel has provided two examples for connecting APSIM to optimisation techniques.  These serve to demonstrate contrasting approaches in connecting APSIM to optimisation software. 

Examples can be found here:

nasapower: NASA POWER Global Meteorology, Surface Solar Energy and Climatology Data Client

International users of APSIM can now enjoy easy access to APSIM metrological files (.met files) from NASA POWER via a new R package developed by USQ’s Associate Professor of Field Crops Pathology Dr Adam Sparks called nasapower now available on CRAN.  One of the functions in this new package takes the NASA POWER agroclimatology data and reformats it into an APSIM .met file for use in APSIM simulations.  Information and documentation for the new package can be found at https://ropensci.github.io/nasapower/.

FEATURES

APSIM next generation

Over 24 years, the Agricultural Production Systems sIMulator (APSIM) has grown from a farming systems framework used by a small number of people, into a large collection of models used by many thousands of modellers internationally. The software consists of many hundreds of thousands of lines of code in multiple programming languages. This infrastructure has successfully integrated a diverse range of models but isn’t capable of easily meeting new demands from modellers. For these reasons, the APSIM Initiative has begun developing a next generation of APSIM (dubbed APSIM next generation) that is a completely new application with no legacy code and designed to run across different platforms. Currently APSIM next generation has limited capability and isn't quite ready for mainstream use. However, if your modelling problems fits within the specified capability, or you simply wish to evaluate this release, then it can be downloaded from the APSIM registration page (look for 'next generation' in the version drop down box). More information can also be found here.

APSIM Oil Palm Model

Palm oil is an important vegetable oil, produced from oil palm grown by many companies and more than a million smallholders worldwide. For growers to make decisions that are good for productivity and the environment, they need to know which practices are best for crop yield, soil fertility, aquatic ecosystems, and to minimise greenhouse gas emissions.   Recent collaboration between ACIAR, James Cook University, CSIRO and the PNG Oil Palm Research Association has developed an Oil Palm model for APSIM.  The model simulates palm growth and development in response to climate, soil and management.  Training workshops have been held in PNG, Indonesia and Malaysia.  A paper describing the new model is available at the following link.

Agricultural Modelling Special Issue

In December 2014, the journal 'Environmental Modelling and Software' published the first part of a new Thematic Issue: "Agricultural systems modelling and software: current status and future prospects". Lead by Dean Holzworth (with 7 co-authors), the Thematic Issue explores the current status of the leading process based agricultural systems models. Models featured in the Issue include APSIM, AquaCrop, CropSyst, STICS / RECORD, APSIM PMF and APSIM OilPalm. There are also a range of other papers covering various aspects of modelling complex agricultural systems. For more information go to the following link.
Part 2 of the Thematic Issue (including a position paper) will be published mid 2015.

New APSIM Paper

The APSIM Initiative and key collaborators have been involved in the development of a new paper titled APSIM - Evolution towards a new generation of agricultural systems simulation. This paper updates the earlier work by Keating et al. (2003) and chronicles the changing external challenges and opportunities being placed on APSIM during the last decade. It also explores and discusses how APSIM has been evolving to a “next generation” framework with improved features and capabilities that allow its use in many diverse topics. The paper is now in print in the journal of Environmental Modelling & Software and available at the following link.

APSIM-Wheat: Documentation

Find out the details of the APSIM-Wheat module and understand how wheat crop is simulated in APSIM.

This updated documentation presents the processes modelled in APSIM-Wheat, and gives the equations and defaults parameter values that are used by the model. Graphic illustrations and figures have been added to help the understanding on how the model is functioning.

The updated documentation can be found here.
