Abstract

IS irrigation scheduling using climate-crop-soil
data practical? Is
this a service that farm managers
might use to increase their management
skills and, hence, their net returns?
Tests using a computer program
to predict the time and amount
of the next irrigation indicate this
type of scheduling is practical and is
a service many farmers would like.
The computer program employs
estimates of daily evaporation and
transpiration for a crop. When combined
with experimental data on allowable
soil moisture depletion for the
crop and various soils, the date of
the next irrigation can be estimated
immediately following each irrigation.
The computer not only predicts
the date of the next irrigation but
estimates the optimum amount of
water to apply as well.
This article summarizes the scheduling
procedure being developed and
the results to date, which have been
discussed in more detail elsewhere.
