The
side roll sprinkler system is a mechanically moved version of a
hand move system with
wheels mounted on the pipeline (see
pictures). It doesn't move while
irrigating.
Side roll is a set irrigation system that is moved from
position to position between irrigation zones. The
movement can be through dragging or by a driven unit
(i.e. by
a small fuel engine).
The Side roll sprinkler system is
similar to the hand move system, it remains
stationary while water is applied. Because they are stationary during
water application, spacing between sprinklers and laterals is based on
wind speed. When the desired depth has been applied, the system is moved
by hand (hand move) or mechanically (side roll) to another section of
the field. Is designed to
be used on crops like vegetables, potatoes, soy beans, forage crops, wheat, barley,
etc. The side roll is limited to crops under 1 m in height. Can be used on
any soil suitable for sprinkler irrigation (care should be taken
on heavy
clay).
It is best suited for level fields that are square or rectangular.
Can be used on a single field or on side by side fields where the lateral
can be moved directly from one field to the other.
The infrastructure of mainlines, submains and
hydrants is identical to a hand move system. However, the portable lateral
lines are replaced by the side roll.
A typical side roll can be 460 - 490 m in
length and it operates along a mainline with hydrants spaced every 60 - 80 m.
The sprinklers are usually medium to
heavy duty
agricultural sprinklers. |
