Computer Models and Decision-Support Platforms for Precision Irrigation Management

Abstract

The irrigation management tools reviewed in this publication serve different but interrelated purposes. The WINDS model functions as a field-scale model for evaluating soil water, salinity, and related processes, while the pyfao56 model is a FAO-56 evapotranspiration and soil-water-balance analysis model designed for customized integration within other software platforms and user interfaces. The OpenET platform provides satellite-derived evapotranspiration data rather than direct management recommendations, and CropManage focuses on crop-specific irrigation and nitrogen management. SWAN Systems is designed as a farm-scale platform that integrates irrigation and nutrient management

Because these tools are intended for different applications, selection should be guided by the required management level and objectives. Platforms such as SWAN Systems and CropManage are better suited for operational irrigation scheduling, particularly when sensor data or crop-specific recommendations are desired. The current version of WINDS is more appropriate for scenario analysis and salinity management, while OpenET is useful for accessing regional or field-scale ET information. In practice, using more than one tool may provide the most effective support, especially when irrigation scheduling, evapotranspiration estimation, salinity management, and automation are all part of the management strategy.
