BENEFITS OF IRRIGATION
The reasons for irrigation are wide and varied and differ for each situation. For example irrigation;
- Provides greater certainty with production than is possible with dryland farming
- Provides options for diversification or intensification
- Allows farmers to grow more pasture and increase livestock production
- Allows farmers to maintain pasture quality over a critical dry period
- Ensures crops are not affected by moisture stress at critical growing times
- Provides greater opportunity to gain a pasture/crop response to fertiliser application
Although irrigation has many benefits, whether to irrigate or not is generally an economic decision. For irrigation to be sustainable, the benefits must increase income sufficiently to cover the costs of development and provide an acceptable return on investment.
ADVANTAGES OF IRRIPOD PLUS SYSTEM
Lower Cost of Ownership
- Allows irrigation of more marginal land
- Simple to add to irrigation scheme as funding allows
- Low pressure system translates into lower running costs
- Only requires one person to shift the lines
- Easy to understand and manage
- Does not require specialist skills or tools
Efficient Water Application
- Low sprinkler height means less wind drift and effective water distribution pattern
- Mimics natural rainfall allowing for efficient soil water absorption and less runoff
- Smaller droplet size means less soil compaction
- Able to be used on flat or rolling country and with odd shaped fields
- Able to be turned on and off without waiting for the irrigation cycle to be completed
- The system can be left on while livestock are in the field
REASONS TO SPECIFY IRRIPOD PLUS
Innovative Robust Design
- The white Pods are highly visible minimising the chance of running over the Irripod Plus system with farm machinery
- Sprinkler Riser, Cross Tee Anchor and Pipe Clamps prevent the pod unit from slipping or twisting on the pipe when shifting the lines
- Wire clip across the top of the Pod provides sprinkler protection against mechanical damage when shifting the lines.
- The heavy, rounded Pod base provides a low centre of gravity, improving the efficiency of shifting the irrigation line
- Easy assembly of the sprinkler on the Pod Skid Base prior to the body being attached saves on installation time.
- Pods are easily replaced without the need to cut or rethread the pipeline
- Pod covers are also available in black to accommodate Pod replacement in existing systems
Multiple Configuration Options
- The system allows for multiple configurations to suit different sprinkler sizes and 32mm, 40mm or 45mm irrigation pipe sizing
New ‘Pop-Up’ Sprinkler Options
- An innovative ‘pop-up’ sprinkler option for 32mm and 40mm pipe.
- Provides an effective solution for pastoral areas that are to be grazed with inquisitive livestock such as horses, deer, bull beef and young stock.
- Pod lid prevents hoof and leg injury in young stock and sprinkler damage from older stock
- High impact UV resistant plastic construction coupled with long life corrosion proof fastenings means Irripod Plus systems are both rugged and durable
Listed below are the typical design specifications. Please note that Mainline and Pump requirements will depend on the design of the system.
Pod Skid Spacing – Pods are typically spaced at 15m intervals on an irrigation line but can be up to 25m with different sprinkler designs
Sprinklers – Typically 15-20mm male, full-circle, impact sprinklers; other types may also be used
Nozzle size – Usually in the size range 2.4-4mm, but this can vary as per specification.
Wetted diameter – Most designers work on 225m2 wetted area after allowing for 15m spacing on the irrigation line and ignoring cross over of sprinklers.
Operating Pressure – Typically 2.5 Bar to 4.0 Bar
- On the tow end of line use a Hansen Tow Eye and Tow Rope.
- Connect to the Hydrant using a Hansen Female Straight Coupler
- Insert a Hansen Barrel Union into the irrigation line if the irrigation line is to be stored or shifted out of the paddock when not in use.
Irripod Plus Hydrant and Pipeline Components
IRRIPOD PLUS TOWING ACCESSORIES AND FENCE SIGNS
IRRIPOD PLUS SPRINKLER OPTIONS
INSTALLING POD SKIDS(BASED ON 15M POD SPACINGS)
The Tow Eye will need to be fitted to the end of the Feed/Sprinkler line that is furthest from the irrigation hydrant. Pipe to be layed with print facing up – will help to take out the memory in pipe.
With the Tow Hook fitting in place, mark a position that is 1m from the Tow Eye fitting. This is where you will install the first Pod Skid
Having completed the assembly of the first Pod Skid, measure along the pipe 15m from the last Pod Skid. This is where you will place the next Pod Skid. You now need to assemble the Pod (repeat Step 3). When you have completed the assemblies of the Pod simply follow Step 4, and Step 3 until you have completed all Pod Skids.
You should now have all the Pod Skids fitted to the Feed/Sprinkler line and the Tow Hook on the sprinkler end of the line 1m from the first sprinkler.
Irripod Plus System Management
- Moving Times – 12 or 24 hours, dependant upon system design
- Return Times – Range from 8 to 14 days and are determined by soil structure, pasture/crop type, water availability and local climate conditions
Moving irrigation lines
Irripod Plus lines have been designed to be moved whilst still operating. The system can be moved simply and safely with very little effort
- Movement is typically done by an ATV. Do not exceed ATV manufacturer’s recommendations for maximum towing weight
- Use markers on the fence to align the irrigation line movements at required increments
- Picking up irrigation lines is typically done using the Hensen Tow Hook and Tow Rope which is secured to the ATV or other farm vehicle
- Ensure the ATV or farm vehicle is facing the direction the line is to be towed.
- In one smooth movement proceed to skid the Feed/Sprinkler line towards the marker sign at the other end of the field. Once the line is in place unhook, and proceed to the next line.
