@carlosalfredomerchan: One millimeter of water equals one liter spread over one square meter. This makes daily evaporation-pan readings easy to convert into liters per square meter. The appropriate coefficients are then applied to estimate crop evapotranspiration and determine how much water should be considered when scheduling irrigation. #AgricultureAndTechnology #CarlosMerchan #Evapotranspiration #Irrigation #Agronomy
