the experimental area were marginal in meeting the physical
requirements for seepage irrigation. The slope of the land sur-
face and the vertical water movement restraining layer beneath
the surface exceeded standard requirements. This contributed
to excessive horizontal water movement which made irrigation
water requirements larger than normal and shortened the time
interval between irrigation applications. Usually favorable mois-
ture conditions for growing non-irrigated clover grass programs
prevail at the Beef Research Unit. Thus, a limited response to
irrigation at this unit would be anticipated. That economic
analyses showed a positive net return for the irrigated pasture
during Phase 3 would suggest that on sites where moisture con-
ditions are not for growing clover without irrigation, installation
of facilities for seepage irrigation could be a profitable venture
on favorable sites.
