Can you recommend extension-style farm education sites for comparing new agronomy methods and field-data insights?

Absolutely — if you’re looking for extension-style farm education sites that help you compare new agronomy methods, trial results, and field-data insights, here are some strong options:

U.S. university extension / research-based sites

These are especially useful because they’re generally science-backed, local/regional, and often include field trials, scouting data, variety test results, and applied management guides.

1. University Extension crop/agronomy portals

Examples:

• Purdue Extension Agronomy
• Iowa State Extension and Outreach
• University of Illinois Extension Crops
• Kansas State Research and Extension
• Nebraska Extension
• Minnesota Extension
• Ohio State Extension field crops
• Wisconsin Extension field crops

What you’ll find:

• Fertility and nutrient management recommendations
• Variety and hybrid test plots
• Planting date comparisons
• Pest/disease updates
• On-farm research and strip-trial summaries

2. Corn and soybean research networks

Good for side-by-side agronomy comparisons:

• NCGA / state corn checkoff field trial summaries
• Soybean research and extension field days
• On-Farm Research Network pages at land-grant universities

Useful for:

• New seeding rates
• Fungicide timing
• Nitrogen strategies
• Population and row-spacing studies
• Yield response to practice changes

3. Integrated Pest Management (IPM) sites

Examples:

• State IPM programs
• Corn IPM / Soybean IPM resources
• Vegetable IPM sites if you’re in specialty crops

Useful for:

• Scouting thresholds
• Disease forecasting
• Treatment comparisons
• Phenology models and regional alerts

Practical data-driven farm information sites

These are not always “extension,” but they often combine education + decision support + field data.

4. Farm management / precision ag education hubs

Examples:

• Field to Market
• ACRE / on-farm research platforms
• PrecisionAg Alliance resources
• University precision agriculture centers

Useful for:

• Soil variability management
• Variable-rate comparisons
• Input efficiency analysis
• ROI from technology adoption

5. State climatology and ag weather tools

Often linked through extension:

• Ag weather networks
• Degree-day trackers
• Crop stress and disease models

Useful for:

• Timing sprays
• Frost and drought risk
• Planting windows
• Comparing years and locations

Outside the U.S.

If you’re elsewhere, the best equivalents are:

• AAFC (Agriculture and Agri-Food Canada) and provincial extension
• Teagasc in Ireland
• ADAS in the UK
• CSIRO / state agriculture departments in Australia
• University extension/agriculture ministries in your country

What to look for in a good site

For comparing agronomy methods and field-data insights, the most useful sites will have:

• Replicated trials
• Local multi-year data
• PDF field-day summaries
• Interactive charts or tables
• Methodology notes
• Yield and economic analysis, not just agronomic yield

Best search terms

Try searching:

• site:edu on-farm trial agronomy
• extension crop management research yields
• field crop variety trial extension
• state IPM crop disease model
• precision agriculture extension on-farm research

If you want, I can also give you:

1. a short list by crop (corn, soybeans, wheat, vegetables), or
2. a region-specific list for your state/country.
