Abstract

The evaporative loss of water from agricultural fields during the nongrowing
season is an important component of the annual water balance of irrigated lands.
This study was conducted to measure daily ET from clipped grass and fallow fields
from October through March and to compare the ET with precipitation received
during the same period. Two weighing lysimeters near Kimberly, Idaho, were
used to measure daily ET for six nongrowing seasons, from 1985 through 1991.
ET averaged about 1 mm/day during the 6-month season, and total El' exceeded
precipitation except for the 1985-86 period. ET from the grass lysimeter exceeded
that from the mostly fallow lysimeter in early fall while the reverse was true
during late winter. The results indicate that there is little, if any, potential for a
net increase in stored soil water during the nongrowing season when fields receive
an early or mid-fall irrigation in southern Idaho.
