Abstract

The construction, operation, calibration, and testing of an irrigation gauge, which gives a direct indication of the soil moisture deficit under a crop, is described in this thesis. A full description of the use of this gauge is given, together with a discussion of the theoretical limitations and practical difficulties which may be encountered when using the gauge. During the growing seasons of 1959 and 1960, the root zone soil moisture of irrigated oat crops as indicated by irrigation gauges was found to agree within approximately one inch of water with measured values determined using a d/m neutron gauge. The accuracy of the d/m gauge, when used to determine root zone soil moisture, was checked, and results have shown that the d/m gauge readins were within 7.5% of readins obtained using oven-dried soil samples.
