What Problem Does This System Solve?
Modern irrigation projects increasingly require precise and repeatable fertilizer application.
Common challenges include:
- Uneven fertilizer distribution across irrigation zones
- Manual fertilizer mixing and dosing
- Difficulty maintaining consistent nutrient concentration
- Lack of feedback on actual fertigation performance
- Complex operation for non-technical staff
The Water–Fertilizer Integration System is designed to address these issues with a modular and scalable approach.
System Overview
This solution integrates:
- Irrigation water control
- Fertilizer dosing
- Optional EC/pH monitoring
- Multi-zone irrigation coordination
It supports both basic scheduled fertigation and advanced closed-loop nutrient control, depending on project needs.
Start simple. Upgrade anytime.
Two Typical Control Approaches
Approach A: Scheduled / Ratio-Based Fertigation
This approach focuses on time-based or ratio-based fertilizer injection.
Key characteristics:
- Fertilizer is injected according to preset schedules
- No continuous EC/pH feedback required
- Simple operation and maintenance
- Cost-effective for most crops
Recommended controller:
- PKY-FG301 – Fertigation Controller
Typical applications:
- Greenhouses with stable crop programs
- Open-field vegetable production
- Orchards with seasonal fertilization plans
Approach B: EC/pH Closed-Loop Fertigation
This approach uses real-time EC and pH feedback to adjust fertilizer dosing automatically.
Key characteristics:
- Continuous monitoring of nutrient concentration
- Automatic adjustment based on EC/pH targets
- Higher precision and consistency
- Suitable for sensitive or high-value crops
Recommended controller:
- PKY-FG401 – EC/pH Fertigation Controller
Typical applications:
- Hydroponic systems
- High-value greenhouse crops
- Precision agriculture projects
How to Choose Between FG301 and FG401
| Selection Factor | FG301 | FG401 EC/pH |
|---|---|---|
| Fertigation method | Scheduled / ratio-based | Closed-loop EC/pH |
| Sensor requirement | Optional | Required (EC & pH) |
| Automation level | Basic | Advanced |
| System complexity | Low | Medium–High |
| Typical users | Growers, integrators | Technical teams |
| Crop sensitivity | Normal | High |
Choosing the correct approach avoids unnecessary complexity and cost.
Integration with PKYDrip Control Systems
The Water–Fertilizer Integration System can be integrated with:
- PKY-60W wired irrigation controllers
- Wireless execution controllers (e.g., IC03 / IC06)
- Sensor monitoring via PKY-DAT01
This enables:
- Centralized irrigation and fertigation management
- Multi-zone coordination
- Expansion as project requirements grow
Typical Deployment Scenarios
- Greenhouse vegetable production
- Hydroponic and soilless cultivation
- Orchard fertigation systems
- Large-scale field irrigation projects
- Demonstration farms and pilot projects
Information Needed for System Design
To recommend a suitable fertigation setup, we typically ask:
- Crop type and growth stage
- Number of irrigation zones
- Fertilizer types and injection points
- Desired automation level
- Whether EC/pH control is required
This ensures correct system configuration and stable operation.
- Unsure if EC/pH control is required?
