New Webcast Helps Consultants and Producers Troubleshoot Deficiencies in Secondary and Micronutrients in Cotton

April 30th, 2014

Memphis, TN --The three primary nutrients - nitrogen, phosphorus, and potassium - tend to get the most attention. But even though secondary and micronutrients have inferior-sounding names, these elements—including calcium, magnesium, iron, zinc, and seven others—are absolutely essential to ensuring healthy cotton plant growth and yield. 

The latest ‘Focus on Cotton’ webcast, titled “Secondary and Micronutrients in Cotton” by Hunter Frame, Assistant Professor and Field Crops Agronomist at Virginia Tech, helps consultants, growers, and other practitioners in the cotton producing regions of the U.S. better understand the role of secondary and micronutrients in cotton production. 

This presentation specifically covers:

  •  Basic troubleshooting tips to identify nutrient deficiencies
  • The physiological functions of secondary and micronutrients in plant health
  • The locations in the cotton plant where these nutrients accumulate
  • Guidance on plant tissue sampling and forwarding for laboratory analysis to confirm nutrient deficiencies

The ‘Focus on Cotton’ resource now contains 15 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. The resource also features a new and improved Cotton Extension Search tool where users can conveniently search for extension resources across all universities serving cotton producers.
