We have beta release of a multi-layer water balance in PCSE-WOFOST. Most common is a single bucket model with the root-zone bucket increasing with increasing root depth. Q: How did define root zone moisture content? is that based on different soil depths? how did you define root depth?Ī: WOFOST can have different implementations of a soil water module for simulating the root zone moisture content.

Besides this WOFOST version is still under maintenance to get it aligned with the official WOFOST implementations.

It also has WOFOST implemented but it misses the ion toxicity. In Wageningen we do have the SWAP model, it simulates sub surface hydrology and includes sailinite. Q: Does WOFOST simulate soil salinity, does it consider ion toxicity effect on crop production? Is it useful for both saline area and drought area?Ī: It is not included in the model, it does not simulate toxicity effect. To us it is not clear what the advantage would be, there are already at least 14 different implementations of WOFOST in different languages I do not see the added value of a WOFOST implementation under DSSAT. Q: Can we integrate DSSAT and WOFOST? or any comparative studies have been done before?Ī: To us it is uncertain what you mean with “integration”? DSSAT is a suite of models, so if your aim is to implement WOFOST as part of the DSSAT suite that is possible. However we do have model frameworks: PCSE (Python) and WISS (Java) in which we implemented WOFOST. DSSAT and APSIM or more modelling frameworks with different models implemented. The different models can have different aims e.g. Models arose within science groups around the world. Q: Why are there a large number of crop models? what is the difference between WOFOST and DSSAT or APSIM?Ī: Historically grown. Team Earth Informatics at Wageningen Environmental Research Senior scientist, agro-meteorology and remote sensing After their presentation, webinar attendees will have the opportunity to ask any WOFOST-related questions. In this webinar, organized by the Crop Modeling Community of Practice, a panel of WOFOST experts formed by Allard de Wit and Hendrik Boogaard will introduce WOFOST, explain the basic principles and show some applications including a hands-on training by means of Jupyter Notebooks. In the Global Yield Gap Atlas (GYGA) WOFOST is used to estimate the untapped crop production potential on existing farmland based on current climate and available soil and water resources. It is one of the key components of the European MARS crop yield forecasting system. sowing date).Īs an open source model, WOFOST has been used by many researchers over the world and has been applied for many crops over a large range of climatic and management conditions. for a location given knowledge about soil, crop, weather and crop management (e.g. With WOFOST, you can calculate potential and attainable crop production, leaf area, water use, etc. It is a mechanistic, dynamic model that explains daily crop growth on the basis of the underlying processes, such as phenological development, CO 2-assimilation, transpiration, respiration, partitioning of assimilates to the various organs, and dry matter formation and how these processes are influenced by environmental conditions.

WOFOST is a simulation model for the quantitative analysis of the growth and production of annual field crops.
