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.
