Fertigation System Architecture

Connect fertilizer injection, EC/pH monitoring, dosing logic, and irrigation zones into one controlled fertigation structure.

Typical Applications

Greenhouse fertigation

Irrigation-linked fertilizer injection for controlled crop production.

Hydroponic nutrient control

EC/pH monitoring and nutrient solution management.

High-value crops

Strawberry, blueberry, vegetables, and nursery projects.

Farm irrigation upgrades

Add fertigation control to existing pumps, filters, tanks, and pipelines.

Fertigation System Structure

A complete fertigation system includes hydraulic equipment, fertilizer injection equipment, EC/pH monitoring, dosing control, and irrigation coordination. The controller is one module inside this larger system.

  • Water source and pump provide the hydraulic base
  • Filters protect downstream valves and drip lines
  • Fertigation unit injects fertilizer into the irrigation flow
  • EC/pH sensors provide nutrient and acidity feedback

EC and pH Control

EC control helps manage nutrient concentration. pH control helps adjust acidity according to crop and water quality requirements. Control logic depends on sensor feedback, dosing equipment, and project configuration.

  • Target EC value for nutrient concentration
  • Target pH range for crop requirements
  • Sensor feedback before or after mixing depending on system design

Dosing Pump Logic and Recipes

Dosing pumps can be controlled by time, proportional dosing, or recipe-based logic. Recipe management is useful for greenhouse, hydroponic, strawberry, blueberry, and other high-value crop projects.

  • Multi-channel fertilizer dosing
  • Acid or alkali dosing for pH adjustment
  • Crop-stage recipe settings when required

Typical System Structure

A fertigation system adds fertilizer injection and nutrient monitoring to the irrigation pipeline so water and fertilizer can be managed together.
