Abstract
As the demand for water and the
cost of irrigation continue to increase,
agriculture must increase
its efficiency of water use. As farms
become larger and skilled irrigators
more scarce, good irrigation water
management becomes more difficult.
Even though scientific research
has developed many principles that
can greatly improve irrigation water
management, determining when to
irrigate has not changed significantly.
A solution to this need is a
method of determining how much
water is used each day in plant
transpiration and soil evaporation
from easily obtainable meteorological
data. The sum of evaporation
and transpiration is commonly called
evapotranspiration. At the Snake
River Conservation Research Center,
we are developing such procedures
from studies of evapotranspiration
as related to weather conditions,
the type of crop, the amount
of plant growth, the stage of growth,
and the wetness of the soil surface.
