Planning and Operating Pecan Orchards
with Drip and Microspray Irrigation Systems
Adapted1 by Esteban Herrera, Extension Horticulturist
Theodore Sammis, Research Water Specialist
Drip irrigation allows precise application of water
to plant roots. Small amounts of water are applied fre-quently
to replace water withdrawn by the plant or
lost by evaporation or deep seepage. Soil moisture in
the area around the plant is thus maintained at a uni-form
level throughout the growing period. This in-creases
growth and production potential because
plants are not subjected to wet and dry cycles that
normally occur with other irrigation methods.
Drip irrigation simplifies irrigation procedures,
minimizes distribution and evaporation losses, and
may reduce labor requirements. Less of the total soil
area is wet with drip than with sprinkler and furrow
systems, significantly reducing water required for ir-rigation
and simplifying weed control. The irrigation
system can be controlled automatically with a time
clock and/or soil moisture sensors and automatic
valves, thereby maintaining optimal soil moisture
with minimum labor. Drip irrigation is used more of-ten
for orchard crops than for field crops, primarily
because the spacing between emitters and laterals is
greater, and system costs per acre are lower.
DRIP IRRIGATION SYSTEM LAYOUT
Water is distributed to individual trees through a
pipeline system that should be planned carefully for
the specific site, orchard size and shape, land slope,
tree spacing, and water requirements. The system
should provide reasonably uniform pressure at all
emitters, require minimum material, and achieve max-imum
operating convenience.
Components of a typical drip irrigation system are
illustrated in fig. 1. The pipeline is composed of a
main line that carries water to manifolds and laterals.
