Soil water under forested and cut areas on northwest and southeast aspects was measured with a neutron probe system at weekly intervals to study soil water deficit patterns under these conditions. Soil water deficits were significantly different among years, seasons, and vegetative covers. Summer deficits increased at the average rate of 2.1 mm/day on the forested and 0.6 mm/day on the cut areas. Average seasonal deficits for forested and cut areas, respectively, were: spring, 23 mm and 16 mm; summer, 104 mm and 34 mm; fall, 230 mm and 45 mm; and winter, 108 mm and 24 mm. No signficiant differences were found between soil water deficits on northwest and southeast aspects.
