Active light sensors and rate controllers are increasingly used to measure real-time variations in plant health and manage the variable rate application (VRA) of liquid inputs for cotton including plant growth regulators, nitrogen, defoliants, and boll openers.
The new Focus on Cotton webcast - Equipment Mounted Sensors for VRA in Cotton - helps cotton growers, consultants, and other industry experts understand the challenges and opportunities of using sensor-based VRA technologies in cotton production.
The 20-minute discussion talk by Randy Taylor, Extension Agricultural Engineer at Oklahoma State University, provides information that helps users understand:
- Differences between map and sensor based VRA
- Limitations of sensors and VRA equipment
- The importance of using and optimizing prescriptions for VRA
- Adjusting rate controllers for use with sensor systems
The webcast is available through the ‘Focus on Cotton’ webcast resource located at the Plant Management Network.
‘Focus on Cotton’ contains nearly 30 webcasts on various aspects of cotton crop management. These talks - freely accessible 24 hours a day, 7 days a week - cover agronomic practices, crop protection, and ag engineering.
This resource also features a new and improved Cotton Extension Search tool, where users can conveniently search for extension resources across all U.S. land-grant universities serving cotton producers.
