Serbia is one of Europe’s key corn-producing regions, where large-scale field operations require high efficiency and precise chemical application.
However, traditional herbicide spraying methods often struggle with inconsistent pressure control, variable working speeds, and chemical overuse — especially in large and uneven fields.
To address these challenges, Serbian farmers adopted the FJD ATS-C Precision Sprayer Controller, integrated with OEM valve systems such as GEOline, enabling closed-loop flow control and significantly improving spraying consistency across corn fields.
Operational Challenges in Traditional Spraying
Before adopting precision spraying technology, herbicide application in corn fields faced several key issues:
1. Inconsistent Application at Variable Speed
Spraying performance often fluctuated due to changing tractor speeds, leading to:
- Uneven chemical distribution
- Over-application in slow zones
- Under-application in high-speed zones
2. Pressure Instability
Traditional spraying systems struggled to maintain stable pressure in real time, resulting in:
- Irregular atomization quality
- Reduced herbicide effectiveness
- Higher chemical consumption
3. High Chemical Waste
Due to a lack of precise control, chemical usage efficiency remained low, resulting in significant cost losses in large-scale operations.
Solution: FJD ATS-C × GEOline Closed-Loop Control System
The integration of FJD ATS-C with GEOline Valve enables a fully automated closed-loop spraying system designed for precision agriculture applications.
Core Functions
- Variable Rate Spraying Control: Automatically adjusts flow rate based on real-time vehicle speed to maintain consistent application per hectare.
- Precise Flow Regulation: Maintains a stable target application rate of 180 L/ha, ensuring consistent output across all operating conditions.
- Stable Pressure Management: The system maintains constant 4 bar pressure, ensuring uniform chemical atomization.
- Real-Time Monitoring Interface: ATS-C displays key operational data including:
- Flow rate
- Pressure level
- Sprayed area
- Application status
- 5-Section Independent Control: Supports simultaneous management of up to five spray sections, improving efficiency in large-field operations.
- High Precision Control Accuracy: The system maintains application deviation within <3% under controlled test and field conditions, ensuring reliable consistency.
Performance Improvements in Field Operations
With the integration of ATS-C and GEOline Valve, corn herbicide spraying operations in Serbia achieved significant improvements:
- Higher Application Consistency
Precise closed-loop control ensures uniform chemical distribution across varying terrain and speed conditions.
- Reduced Chemical Consumption
Compared with traditional spraying methods, chemical usage was reduced by approximately 15%.
- Improved Operational Efficiency
Automation of flow and section control reduces operator workload and improves field productivity.
- Stable Spray Quality
Constant pressure control ensures uniform atomization, improving herbicide effectiveness.
Precision That Matters in Large-Scale Corn Production
In large corn fields, small inefficiencies can quickly scale into significant cost losses. By combining real-time flow adjustment with multi-section control, the ATS-C Precision Sprayer Controller ensures that every liter of herbicide is used effectively, improving both economic efficiency and agronomic outcomes.
Conclusion
The FJD ATS-C × GEOline system demonstrates how precision spraying technology can transform herbicide application into large-scale corn farming. By enabling real-time flow control, stable pressure management, and multi-section automation, the system helps farmers achieve higher efficiency, lower chemical waste, and more consistent field performance. FJD ATS-C ensures that every liter of herbicide is used where it counts—supporting smarter, more efficient, and more sustainable crop protection practices.
