Irrigation efficiency and optimization: the Optirrig model

Abstract

Developed by INRAE, Optirrig is a software tool for generating, analysing and optimising irrigation scenarios. It is based on a simplified description of plant growth according to the evolution of water and nitrogen resources in the soil. It compares the merits of different irrigation strategies according to different constraints (water quota, periods of limited availability, prefectoral decrees, water and energy costs), for operational objectives at the plot, farm or territory level.
