Abstract

A technique was developed to partition the soil profile of plotted plants of Atriplex confertifolia so that soil water condition could be controlled at specific depths. During an experiment in August in a field environment, plant water status was more stressed when soil water availability was restricted to the top 10 centimeters of the profile compared to the deeper 30 to 40-centimeter zone. Soil water was more beneficial, however, when it was available throughout the profile.
