Abstract

A spatial soil water balance modelling approach that utilized remote sensing and ground-based data was developed to guide surface irrigation scheduling of farm-size cotton borders in a field experiment in Arizona, USA. The objective was to evaluate spatial estimates of daily crop evapotranspiration (ETc) calculated for small, 4 × 8 m cells within 12 × 168 m cotton borders. Estimated ETc rates during the season compared favourably with ETc data based on soil water content measurements, though underestimating field-based ETc by an average of 0.25-0.46 mm/d. Results suggest that the spatial modelling approach could be a useful decision-making tool for improving irrigation scheduling of surface-irrigated fields.
