Abstract

Today's farmer has a choice of nine major types of sprinkler systems and many
versions of each type. The nine major types are handmove, tow line, giant
sprinkler, side roll, side move with and without trail lines, solid set,
center-pivot, self-propelled straight lateral, and self-propelled gun traveler.
All sprinkler types except the handmove are mechanical-move systems. The first
six major types are stationary systems -- the sprinkler or sprinklers apply
water while operating in a fixed position in the field. The last three types
are moving systems -- the sprinkler or sprinklers apply water while continuously
moving over the field.

Uniform water distribution by sprinkler systems is essential to optimize crop
yield and quality; allow minimum sprinkler system capacity; conserve pumping
power, and make more efficient use of the available irrigation water supplies.
It is very important where the system is used to apply fertilizers and pesticides
in irrigation water. To obtain uniform water distribution in the soil
with sprinkler systems, the application rate should be equal to or less than
the intake rate and surface storage capacity of the soil so that there is no
runoff or water movement on the soil surface.
