When asked to mention one,
single advantage that
investing in an irrigation
system could yield, our
constant answer is insurance.
Insurance against crop/turf
failure and insurance
that land will be better
utilized (increased profitability
without purchasing more
property). Combined with
improved growing conditions
plus -- for agricultural
and turf customers alike
-- the benefits of better
product quality/appearance,
the system you employ
will pay for itself many
times over. Vanden Bussche
experts will lead you
to a greener world, utilizing
the finest equipment in
any of the following,
irrigation methods.
Sprinkler Irrigation
Pumped water is distributed
through a network of buried
or above ground pipes
to sprinkler head arrays
in a circular pattern
with up to a 50% overlap
- it can be applied as
an aerial spray either
above or below the crop
canopy. For golf courses,
automatic controls are
often integrated into
the turf irrigation system.
Hand-Move Portable and
Semi-Permanent Systems
Evenly spaced lateral
pipes are fed by a movable
main truck line; each
lateral irrigation set
waters one section of
the field and is then
moved until the sequence
covers the entire area.
In a permanent system
the main line(s) is buried
and often more than one
lateral line is employed.
Solid-Set Permanent
Systems
A network of lateral and
main supply pipe, and
riser pipes with sprinklers,
cover the entire field.
In operation, either all
or part of the area can
be irrigated which allows
flexibility of both rates
and volumes (i.e., smaller
volumes applied more frequently).
This is an excellent system
for frost protection/cooling,
plus buried pipe does
not obstruct machine traffic
or require moving.
Fixed-Volume Big Gun
(Hand-Move and Travelling
Systems)
Water is supplied by aluminium,
rigid or flexible plastic
pipe to a series of high-volume,
circular-action, brass
sprinklers (guns) that
can project water up to
150 feet. Guns are moved
by hand from setting to
setting. Travelling gun
systems use a mobile reel
device, located at the
end of a row, to pull
a sled-mounted gun down
the field - irrigating
as it goes. Only semi-circle
gun sprinklers are used
in travelling systems,
to avoid the sled being
pulled through wetted
soil.
Low Pressure Boom Travelling
System
Rather than using a big
gun, in this system, water
is applied by a boom equipped
with low pressure, rotary
spray nozzles. As with
travelling systems, a
reel pulls the boom across
a large field area.
Center Pivot and Lateral
Move System
In many large acreage
applications, pumped water
is fed to a single lateral
- equipped with many sprinklers
- supported by trusses
and towers on wheels.
One end of the system
is anchored to a fixed
pivot centre and the other
end is free to move in
a circle about the pivot.
Towers supports, often
200 feet apart, are driven
by electric or hydraulic
energy and auxiliary guns
are often installed at
the end to irrigate corners.
In a lateral move configuration,
the entire elevated unit
moves sideways down the
field to cover a rectangular
section.
Micro-Irrigation
This form of irrigation
is very precise, easily
automated and it can also
be used to add chemigation/
fertigation to the water
application operation.
Often called 'trickle
or drip', micro-irrigation
consists of a pumped water
source, filtration system,
flow meter, mainline,
header lines, lateral
lines and in-line emitters
that can compensate for
flow rate variances over
a wide range of line pressure.
The pressure compensation
feature is essential to
overcome the problem of
slope and distance over
small-diameter plastic
pipe. Some trickle designs
use micro-jet emitters
that are inserted into
the pipe; the decision
to employ spray, drip
or trickle type emitters
and the distance between
units, depends upon the
zone to be wetted and
the crop. For example,
emitters can be placed
at each plant - apple
and peach orchards - or
closer together to provide
a continuous row (such
as tomatoes, strawberries,
melons, blueberries, ornamentals,
greenhouse propagation
beds, etc.).
Nutrient Management
Involves low level spreading of slurry or liquid manure. Slurry is usually collected in a central pit or lagoon and stored until the nutrients are needed for application (usually in the spring & fall). A slurry pump pushes the liquid through pipes or hose to the field. At the field, Polyethylene Pipe or Dragline is connected to a low level applicator and applied. The slurry may then be incorporated in a second pass with an implement or the incorporating tool may be directly attached to the applicator bar.
