The Right Fertilizer, in the Right Place, in the Right Amount.
AGRO4-VRA reads satellite- and biomass-based prescription maps live in the field and automatically adjusts fertilizer zone by zone. As a KIT that mounts on your existing machine or a fully Integrated system β precise, waste-free fertilization.

Variable-Rate Application in Three Steps
Prescription Map
In the mobile app, a variable-rate fertilizer prescription is created for the field from satellite/biomass-based crop growth maps. The system calculates the total fertilizer amount automatically.
Field Application
The prescription is transferred to the machine. The ECU and linear actuators adjust the discharge gates instantly according to tractor speed and position; each zone receives its targeted amount.
Tracking & Reporting
The application is tracked in real time; distribution stops automatically when leaving the field. All data, maps and prescriptions are stored in the web/mobile app.
Capabilities That Make a Difference in the Field
GIS-Based Prescription Mapping
Map-based fertilization via the mobile app; plant growth maps from remote sensing and satellite imagery are used.
Rate Control
The targeted fertilizer amount is applied to each field zone; total fertilizer is calculated automatically from the application map.
Section Control
Distribution stops automatically when leaving the field; overlap and waste are prevented.
Speed-Sensitive Fertilization
Distribution responsive to different travel speeds; fertilization stops automatically when the tractor stops. Fixed-rate application is possible even without tractor/ISOBUS speed data.
Multiple Fertilizer Types & Calibration
Different fertilizer types can be applied; calibration functions by motor movement and fertilizer type are available.
4 Different Fertilization Modes
Manual (scale), manual (speed-sensitive), automatic (map + speed-sensitive) and semi-automatic modes; switch between modes during operation.
Critical Level Alert
Warns when the tank reaches a critical level; data such as coordinates and system temperature are shown.
Web & Mobile Data Access
All data, maps and prescriptions are stored in the web/mobile app and presented to the user.
Task Management
Variable-rate maps are saved as βtasksβ; managed with planned, in-progress and completed states, with live completion percentage tracked.
Resume Where You Left Off
The system automatically resumes an interrupted fertilization task where it left off; no area is skipped.
Segment Management
Distribution is automatically cut when returning to an already-applied area; processed zones are passed over without re-applying.
Day / Night Mode
The screen stays clear and readable in any condition with a day/night mode adjustable from the control panel.
AGRO4 Cloud Infrastructure
All task data, maps and prescriptions are securely stored in the AGRO4 cloud infrastructure; accessible anytime from web and mobile.
Automotive-Grade Hardware
The AGRO4-VRA kit consists of an automotive-grade control unit, multi-band positioning, a touchscreen and precise mechanical actuators.

| Model | Capacity | Width (mm) | Length (mm) | Height (mm) | Weight (kg) | Min. Tractor |
|---|---|---|---|---|---|---|
| CGSA 900 | 970 L | 2050 | 1325 | 1460 | 402 | ~60 HP |
| CGSA 1200 | 1200 L | 2100 | 1325 | 1605 | 433 | ~70 HP |
| CGSA 1500 | 1500 L | 2140 | 1325 | 1675 | 443 | ~80 HP |
| CGSA 2500 | 2350 L | 2500 | 1300 | 1880 | 480 | ~90 HP |
| CGSA 3000 | 3000 L | 2930 | 1300 | 2550 | 572 | ~100 HP |
| CGSA 4000 | 4000 L | 3220 | 1600 | 2420 | 720 | ~120 HP |
Minimum tractor power values are recommendations; the final value should be confirmed based on the selected disc set, fertilizer type and field conditions. Working width is 10β36 m on all models; applicable disc sets: DT 10-16 / DT 18-24 / DT 24-36. Common hardware: tarp cover opening to 2/3, dual slide-gate discharge unit (CGSA Pro), dual mudguards and parking wheels, interchangeable disc set, stainless cast components.
