IrrigTool—A New Tool for Determining the Irrigation Rate Based on Evapotranspiration Estimated by the Thornthwaite Equation

In the context of climate change, irrigation has become a must for ensuring crop production because in some regions, drought episodes became more frequent. The decision to efficiently allocate water resources should be made quickly, based on tools that provide correct information with low computational effort. Therefore, we propose new user-friendly tool—IrrigTool—for assessing rate considering precipitation, temperature, evapotranspiration, soil type, and crop. IrrigTool implements Thornthwaite equations can used identify weakness due stress as an educational tool. Apart from computation, it provides graphical representation results possible comparisons output two locations. application is built Microsoft Excel graphics Visual Basic VBA. user does not have programming knowledge use it. Data monthly precipitation temperature data introduced specified fields, after pressing run button, are automatically displayed. article exemplifies functioning series Romania’s Dobrogea region.
