K-line/Irripod System

K-line/Irripod System Gallery

LOW APPLICATION RATE SYSTEM

This system involves a series of sprinklers each covering a radius of 8-10m, and the whole line is typically moved after 4-5 hours of application, taking similar time to move as a Travelling Irrigator. Volumes pumped from 18m3 to 20m3 per hour.Ideal system for flat terrain with even shape paddock (square /rectangular).

POD SYSTEMS (K-line or Irripod)

Advantages

The pod system is a series of two x 4 to 6 pods in a line that is feed by a hydrant or hydrants in a paddock. The lines of pods are shifted using a four wheel bike from paddock to paddock. The labour content is about the same as a traveling irrigator. The system suits square or rectangular paddocks. To achieve an application depth of 15mm you will need to pump for 3 to 4 hours, based on the standard system design of 18m³/hr. All solids need to be removed so as to avoid blockages.

Low rate of application (4mm to 5mm/hr)

  • 18m³/hr pumping volume
  • Low capital cost


Disadvantages

There is the need to remove all solids from the effluent before pumping into the system. This can be done mechanically, weeping wall and sludge pit or a two pond system (see solid separation). The pod lines are shifted from paddock to paddock. When large volumes are stored it can take along time to pump out the stored effluent due to the pumping volumes

  • Solid separation required
  • Medium to high labour (shift every 3 to 4 hours pumping) up to twice a day
  • Uniformity


Things to consider

The Pod system is a good system option but needs to have all aspects compared to other options available.

  • Labour content
Larger farms can be pumping for long periods of time while emptying the holding ponds. Consider the labour content. Smaller farms aren't affected too much. The labour content is about the same as a traveling irrigator. Pumping volumes are a major contributor

  • Nutrient losses attributed to solids being separated.
Depending on the type of solid separation used, weeping walls, ponds or mechanical there is a nutrient loss that needs to be quantified.
