Abstract

 

A study of spray losses from three low-pressure center-pivot sprinkler irrigation systems was carried out under field operating conditions. The evaporation losses during sprinkling were determined at three different spray-nozzle height from ground surface. The average values for the distribution uniformity, the potential application efficiency, and the uniformity coefficient were calculated.
