Irrigation For Walnut Plantations
We design trickle irrigation systems for walnut plantations. Price is approximately
$350.00 per 140 tree acre (spacing at 15 ft. by 20ft.) The price includes all tubing,
fittings, emitters, pressure regulator and small screen filter ready to hook up
to standard garden hose fittings.
A one acre system would use 3 gallon of clean water per minute for 3 to 4 hours
twice a week under dry conditions depending on soil type. This would apply 2 to
3 gallon of water per tree per cycle. The system needs a minimum of 20psi water
pressure to operate properly.
A general layout diagram is required to design the system.
The tubing is linear low density polyethylene with U.V. inhibitors to prevent breakdown
in sunlight. This should last 8 or more years above ground and longer if it is buried.
It will not split in freezing weather, therefore blowing the system out with air
is not required for winter shut down. Small utility tractors will not damage the
tubing by driving over it, as long as there are no sharp stones to puncture it.
Similar systems are available for pond or river water.. Call for specs.
Shipping costs are $45.00 per system. Shipped U.P.S. or truck freight.
Larger filters and supply lines are available as well as individual fittings and
bulk tubing, please call for current pricing. Low volume emitters available for
large layouts will reduce the gallons per minute required as well as size of tubing,
but do require a longer run cycle. We will advise during design on what kind of
emitter to use. 2 Inch lay flat line for supply and large header is $140.00 per
300 ft roll. I recommend a HondaWH20X pressure pump with a 5 hp. gas engine as the
most reliable pump I have found for pumping out of ponds where no electricity is
available. These cost about $700.00
