Abstract:

TMs report describes a study of daytime dew point distribution within and about the irrigated farmland near Yuma, Arizona. A comparison is made of the moisture content of the air before, during and after passage over irrigated land, using data obtained during the course of a field investigation in the summer of 1954. The pattern of dew point distribution was sampled through observations taken within and about selected crop types in various stages of growth. The results of the study indicate that evaporation and transpiration cause an average increase of 6 to 8 degrees F, in the dew point of the air directly over an irrigated area, but that the lateral extent of this effect is limited to distances of 100 feet or less from the fields. The influence of irrigation agriculture upon humidities in the various testing sites within Yuma Test Station therefore is negligible.
