Conteúdo: 	Sampling and analysis of the soil moisture distribution and the overall water balance in an irrigated area are the central topics of this work. An experimental study was made in a 14-ha, border-irrigated, alfalfa field near Coolidge, in Pinal County, Arizona, during the summer/fall 1983. The water stored in the soil profile and its change with time were normaly distributed, with coefficients of variation of about 10 and 25 percent, respectively. Temporal correlations were significant for storage (about .60), but absent in the other. Variograms were calculated to show the spatial structure of the distributions. An analogous statistical description was presented for the alfalfa yield. Also shown is a methodology to infer errors due to the field calibration of the neutron probe.
