In BioCro: Modular Crop Growth Simulations

Willow model definition

Description

Initial values, parameters, direct modules, differential modules, and a differential equation solver that can be used to run willow growth simulations in Champaign, Illinois and other locations.

To represent willow growth in Champaign, IL, these values must be paired with the Champaign weather data (cmi_weather_data). The parameters already include the clay_loam values from the soil_parameters dataset, which is the appropriate soil type for Champaign.

Some specifications, such as the values of photosynthetic parameters, would remain the same in any location; others, such as the latitude or longitude, would need to change when simulating crop growth in different locations. Care must be taken to understand each input quantity before attempting to run simulations in other places or for other cultivars.

Usage

Format

A list of 5 named elements that are suitable for passing to run_biocro, as described in the help page for crop_model_definitions.

This model was originally described in Wang et al. (2015) [\Sexpr[results=rd]{tools:::Rd_expr_doi("10.1111/pce.12556")}]. Since its original parameterization, the behavior of several of its core modules has changed as bugs have been identified and fixed, so this model likely needs to be reparameterized before it can be used for realistic simulations.
