What are the best free agronomy insight newsletters for practical crop scouting examples and field monitoring tips?

Here are some of the best free agronomy newsletters if you want practical crop scouting examples, field monitoring tips, and season-specific observations:

Strong free options

1. Crop Protection Network (CPN) newsletters

• Focus: disease scouting, insect issues, crop stress, and diagnostic examples
• Best for: practical “what to look for in the field” guidance
• Why it’s useful: excellent photos, symptom comparisons, and management context
• Website: https://cropprotectionnetwork.org

2. University Extension crop newsletters

These are often the most practical and regionally relevant.

• Examples:
  • Iowa State Extension
  • University of Nebraska-Lincoln Extension
  • Purdue Extension
  • University of Illinois Extension
  • Kansas State Extension
• Focus: weekly crop conditions, pest alerts, scouting notes, field observations
• Best for: field-by-field scouting timing and local recommendations
• Tip: search for “crop watch,” “agronomy newsletter,” or “field crops newsletter” plus your state

3. Integrated Crop Management / field crop newsletters from Extension

• Focus: scouting crops through the season, stand counts, emergence issues, disease pressure, nutrient problems
• Best for: diagnostic field examples with practical decision thresholds
• Good for: corn, soybean, wheat, cotton, sorghum depending on region

4. University plant pathology or entomology scouting alerts

• Focus: pests and diseases as they emerge
• Best for: early warning and monitoring tips
• Often includes: trap counts, disease risk maps, scouting checklists

5. Precision agriculture / agronomy company newsletters

Examples include newsletters from:

• Granular / Corteva-related agronomy content
• BASF / Syngenta / Bayer agronomy updates
• FarmLogs-type educational content
• Focus: general crop monitoring, variable-rate insights, field tech, scouting workflows
• Best for: practical field monitoring systems, not always as technical as Extension

Best if you want very practical scouting examples

If your priority is photos, symptom identification, and “how to scout this week” guidance, I’d rank them like this:

1. Crop Protection Network
2. Your state Extension crop newsletter
3. Regional university field crop updates
4. Extension pest alerts / diagnostic blogs
5. Agronomy company newsletters

A useful scouting newsletter usually has:

Quick recommendation by crop
