Crop parameter sets for FraNchEstYN

A named list of predefined crop parameter sets used in the FraNchEstYN model. The top-level names correspond to crop types (e.g., `"wheat"`, `"rice"`).

Usage

cropParameters

Format

A named list of crop parameter sets: cropParameters[[crop]][[parameter]] → parameter details list.

Details

Structure of each crop set:

• Each set is a named list of parameters.

• Each parameter is itself a list with fields:

  • description — description of the parameter

  • unit — unit of measurement

  • min, max — allowed bounds

  • value — default value

  • calibration — logical; if TRUE, the parameter can be optimized during calibration
