Fertigation Dosing Unit

Closed-loop EC and pH correction on every irrigation event, not once per tank.

A six-channel fertigation skid that measures and corrects EC and pH inside each irrigation event, with dual-sensor verification before water reaches the crop.

  • Six independent stock channels plus dedicated acid and base
  • In-line EC and pH correction within a single irrigation event
  • Dual measurement cells with automatic cross-check and lockout
  • Recipe library with per-crop-stage nutrient schedules
  • Drain flow and drain EC logged for every valve group

Indicative lead time: 8 - 10 weeks

Correcting inside the event

Batch tank systems mix a volume, measure it, and irrigate. If the recipe drifts, the whole batch drifts with it. The dosing unit injects and measures continuously in the delivery line, so a deviation is corrected within a few seconds of appearing rather than at the next tank fill.

Two cells, one decision

Every measurement point carries two independent cells. Agreement within tolerance allows dosing to continue. Disagreement halts injection, flushes clean water, and raises an alarm. In eleven years of installed units this arrangement has never let an out-of-spec solution reach a crop.

Drain as a control input

Drain volume and drain EC are measured per valve group and fed back into the irrigation strategy. Rather than irrigating on a fixed clock, the unit targets a drain percentage band appropriate to the crop stage, which is where most of the water saving in a retrofit actually comes from.
