optirrigBEET: Modeling and Optimization for sugarbeet cases : R Package add-on

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 nitrogen requirements and estimates crop yields, both in financial and biomass terms.

What is the “optirrigBEET” package ?

The optirrigBEET package in R is a specialized adaptation of the Optirrig model, originally developed as part of the optirrigCORE package. Its main objective is to optimize the simulation of sugar yield for sugar beet crops. This package facilitates the extraction and formatting of observation data required by the model, as well as the integration of specific descriptions of plants, soil, and yields relevant to sugar beet cultivation.

As an adaptation of optirrigCORE, optirrigBEET inherits its core functionalities and relies on optirrigCORE as a dependency. It supports various analytical methods, such as Ex-Post and Ex-Ante analyses, with the aim of designing optimized irrigation schedules based on precise criteria for sugar beet production. The package includes all necessary calculation tools to describe biophysical processes with a generalist approach, while also catering to the specific needs of sugar beet cultivation.

Furthermore, optirrigBEET automates the modeling process, the description of biophysical processes, and the analysis of results and performance, ensuring a reproducible approach. It also makes it easy to compile results in automated reports, streamlining the entire analytical process.
