Variable Rate Technology
- Uses photoelectric sensors
to measure tree canopy
- Efficient technology,
especially when resetting trees in mature groves
- Study demonstrated that
fertilizer inputs can be reduced by up to 40% using VRT spreading equipment (Schumann, 2007)

Estimated Nitrogen Reduction from Farms Implementing BMPs
- 272 Crop farms using BMP
Tools on 175,000 acres
- At 50 lbs N/acre reduction
Estimated reduction in lbs of N applied per year 8,750,000 (4,375 tons)

Commissioner Putnam
- Agriculture is a key water stakeholder; both
as a user and as a source of water recharge, and water storage
- Responsible water policy will utilize
technology, sound science, public awareness and collaboration to achieve its objectives
- Flexible, Comprehensive, and Long-Term
