Interpretive Summary:

Technical Abstract: Evapotranspiration (ET) data for maize grown in sprinkler irrigated lysimeter fields at the USDA CPRL were compared with ET data from adjacent subsurface drip irrigation (SDI) lysimeter fields. ET data following the sprinkler applications were used to characterize and quantify differences in ET between the sprinkler and SDI irrigated fields. ET data from the SDI fields were considered as baseline ET scenario with minimal evaporation from soil and plant surfaces. By comparison, excess ET from sprinkler irrigated fields was attributed to evaporative losses. Analyses include comparisons from irrigation events throughout entire cropping seasons including LAI and crop canopy data. These data may help quantify evaporative losses associated with both mid-elevation spray application (MESA) and low elevation spray application (LESA) irrigation systems in semiarid environments.
