Introduction
Description of the “Optirrig” model
Optirrig is a 1D conceptual model designed to simulate irrigation schedules. It uses a thermal time approach, taking into account crop development based on cumulative temperature. The model describes plant growth processes, such as leaf area index (LAI), water stress and biomass produced. It also integrates a soil water balance by describing soil characteristics and conceptual reservoirs for the useful reserve. It also assesses to estimates crop yields, both in financial and biomass terms.
What is “OptirrigCORE” package ?
The OptirrigCORE package in R is based on the Optirrig model. It facilitates the extraction and formatting of observation data used by the model, as well as the integration of plant, soil and yield descriptions. It supports various analytical methods, such as Ex-Post and Ex-Ante analyses, with a view to drawing up an optimised irrigation schedule based on the criteria. The package includes all the calculation tools needed to describe biophysical processes with a generalist approach. It can be used as a dependency or complement to modify and reinterpret biophysical descriptions. What’s more, it automates the modeling process, the description of biophysical processes and the analysis of results and performance, guaranteeing a reproducible approach. It also makes it easy to compile results in automated reports.
Installation
Then you can install the development version of OptirrigCORE like so:
install.packages('OptirrigCORE', repos = c('https://inrae.r-universe.dev', 'https://cloud.r-project.org'))
