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 such as plant growth regulators, nitrogen, defoliants, and boll openers.
A new Focus on Cotton webcast titled “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 presentation by Randy Taylor, Extension Agricultural Engineer at Oklahoma State University, provides information to help users understand the differences between map and sensor based VRA, the limitations of sensors and VRA equipment, the importance of using and optimizing prescriptions for VRA, and how to adjust rate controllers for use with sensor systems.
This webcast is part of the Focus on Cotton series made available by the Plant Management Network and Cotton Incorporated. The Focus on Cotton series contains more than 30 webcasts on various aspects of cotton crop management, including agronomic practices, crop protection and ag engineering. The presentations are accessible online at any time.
The resource also features a newly improved Cotton Extension Search tool, where users can conveniently search for extension resources across all U.S. land-grant universities serving cotton producers.
