Crop submodel

Eventually, the plan is to have Persefone include a reimplementation of the AquaCrop model, a well-established crop growth model developed by the FAO. Until then, we are using the crop growth submodel used in ALMaSS.

farmplot.jl

This file is responsible for the farm plots, i.e. the indidivual fields that farmers manage.

Persefone.FarmPlot — Type

FarmPlot

A struct representing a single field, on which a crop can be grown.
