Abstract

Intermountain drylands lose water from the root zone
during the summer of fallow even though they receive
a monthly average of 3.1 cm of precipitation. Soil water
content in the 7.5- to 15-cm seed zone at the end of
summer fallow was related to soil water content at the
time tillage was initiated in the spring. Fall soil water
content was not appreciably affected by variations in
summer rainfall. Adequate soil water for winter wheat
(Triticum aestivum L. em Thell) emergence was best
assured by initiating summer fallow tillage when the
water content in the 7.5- to 15-cm layer was relatively
high, rather than depending on summer rain to rewet
this layer.
