Smart Agricultural Precision Fertigation Machine | Automatic Fertilizer Injector System

The Smart Fertigation Machine is the core equipment for achieving seamless water and fertilizer integration in modern agriculture. By dissolving fertilizers and thoroughly mixing them with irrigation water, this system delivers nutrients directly to plant roots via advanced irrigation networks.

Integrating industrial-grade sensors and automated control technology, the system precisely blends various concentrated liquid fertilizers with irrigation water based on pre-set formulas. By providing real-time monitoring of the solution's EC (Electrical Conductivity) and pH (Acidity/Alkalinity), it ensures crops receive the ideal nutrient supply at every growth stage. This precise control maximizes fertilizer utilization, minimizes waste, and prevents environmental pollution, making it an indispensable asset for modernized, high-efficiency agricultural production.

The system consists of five modular, industrial-grade components:

1. Proportional Fertilizer Dosing Unit: Driven by a specialized servo injection pump, continuously adjustable from 0.1% to 10% with a 0.1% precision rate.
2. Multi-Channel Suction Unit: Features 3 to 5 independent pipelines equipped with specialized filters and anti-backflow check valves for safe, simultaneous mixing.
3. High-Efficiency Mixing Unit: Employs a large-diameter spiral mixing pipe ensuring a mixing uniformity rating of ≥ 98%.
4. Intelligent Measurement & Control Unit: Powered by an industrial PLC controller, touchscreen interface, and German-imported EC/pH sensors with built-in support for 24-zone control and Mobile App remote access.
5. Safety Protection Unit: Built-in water inlet filters, safety relief valves, and non-return check valves to protect system hardware.

The system operates on an advanced Flow Synchronization + Closed-Loop Feedback loop:

• Flow-Sensing Synchronization: The main pipeline flow meter monitors water flow in real-time. The PLC instantly calculates and regulates the servo dosing pump's rotational speed according to pre-set ratios, guaranteeing injected fertilizer volume remains strictly proportional to total water volume.
• Closed-Loop Feedback: Once mixed, the solution passes through high-precision German EC/pH sensors. If any deviation from target concentration is detected, the PLC adjusts dosing pump speed dynamically, correcting and stabilizing the solution within 30 seconds.
• Automated Zoning: The system sequentially opens targeted zone solenoid valves according to programmed schedules, executing automated, hands-free customized irrigation.

• Compatible Irrigation Systems: Drip irrigation, sprinkler systems, micro-irrigation, and misting setups.
• Cultivation Modes: Commercial greenhouses, open-field farming, orchards, and substrate/soilless cultivation.
• Target Crop Types: Vegetables, fruits, flowers, traditional Chinese medicinal herbs, and broadacre field crops.
• Applicable Fertilizer Types: All water-soluble chemical fertilizers, organic liquid fertilizers, and bio-bacterial liquid fertilizers.
• Highly Recommended For: Precision-driven, high-value commercial cash crops requiring rigorous nutrient management.

The machine is highly adaptable to existing infrastructure and supports two primary installation configurations:
