Introduction
The document introduces the Variable Rate Spreader Mod. 150 VRT by Claudio Pontremolesi, highlighting its role in precision agriculture. The spreader is designed to optimize fertilizer distribution in vineyards by using geographic intelligence to address non-homogeneous areas.

Precision Agriculture and Geographic Intelligence
The spreader utilizes telemeasured data to create georeferenced prescription maps, which help in understanding the variability of vineyard plots. This approach aims to improve economic and environmental outcomes by ensuring uniformity in vegetation and reducing fertilizer use.

Technology and Standards
The machine employs the ISOBUS standard (ISO 11783), allowing a single Virtual Terminal on the tractor to control all compatible tools and manage variable rate maps. This facilitates automatic dose adjustments as the machine moves across different vineyard areas.

Benefits
The spreader offers several advantages: improved agronomical practices, cost reduction through decreased fertilizer use, and a low environmental impact by minimizing unnecessary nitrogen fertilizer application.

Technical Specifications

• Width: 1.60 m
• Capacity: Approximately 780 liters
• Localized surface distribution: Under the two rows
• Weight: 120 Kg
• Speed: 3/6 km/h

Conclusion
The Variable Rate Spreader Mod. 150 VRT represents a significant advancement in vineyard management, offering economic, environmental, and quality benefits through precision agriculture techniques.
