What are the best sustainable agriculture blogs for comparing cover crops and rotation strategies on large-scale farms?

Here are some of the best blogs and online publications for comparing cover crops and crop rotation strategies on large-scale farms. I’m focusing on sources that are practical, research-informed, and relevant to commercial-scale acreage.

Best sources

1. SARE (Sustainable Agriculture Research and Education)

• Why it’s good: One of the most practical, farmer-tested resources on cover crops, rotations, soil health, and economic tradeoffs.
• Best for: Side-by-side comparisons, regional trial results, and management guides.
• Look for: Crop system guides, cover crop species charts, and rotation planning resources.
• Website: sare.org

2. University Extension blogs and field notes

A lot of the best large-scale advice comes from land-grant universities rather than standalone blogs.

• Examples:
  • Iowa State Extension
  • University of Nebraska-Lincoln Extension
  • Purdue Extension
  • University of Minnesota Extension
  • Penn State Extension
• Why it’s good: Region-specific, data-backed, often includes replicated trials and economics.
• Best for: Corn-soy systems, small grains integration, and yield/weed suppression comparisons.

3. No-Till Farmer / No-Till Farmer blog

• Why it’s good: Very practical for commercial-scale producers using cover crops in no-till or reduced-till systems.
• Best for: Equipment, seeding timing, cash crop interactions, and real-world farmer case studies.
• Website: no-tillfarmer.com

4. Corn Belt-focused soil health blogs

These often have strong content on rotations and cover crop performance in row-crop systems.

• Examples:
  • Ag PhD soil health content
  • Practical Farmers of Iowa
  • Minnesota Soil Health Coalition
• Why it’s good: Good blend of research and on-farm experience.
• Best for: Comparing cereal rye, radish, clover, oats, vetch, and mixes in corn/soy rotations.

5. Practical Farmers of Iowa (PFI)

• Why it’s good: Excellent farmer-led trials and detailed reports.
• Best for: Large-acreage rotation strategies, cover crop termination timing, yield impacts, and economics.
• Website: practicalfarmers.org

6. NRCS / USDA soil health resources

• Why it’s good: Not a blog in the classic sense, but very useful for technical guidance.
• Best for: Planning rotations and cover crop mixes based on soil function goals.
• Useful for: Erosion control, nitrogen scavenging, compaction, grazing integration.

7. Cover Crop Strategies / crop consultant blogs

• Why it’s good: More tactical and field-specific.
• Best for: Large-scale operational considerations, herbicide carryover, seeding methods, and termination windows.
• Note: Quality varies, so it’s best used alongside extension and trial data.

What to prioritize when comparing strategies

If you want to compare systems on large farms, the best blogs/resources usually cover:

• Yield impact of different cover crops
• Termination timing
• Cash crop rotation length
• Herbicide interactions
• Soil moisture effects
• Nutrient cycling/N dynamics
• Equipment and seeding logistics
• Regional climate fit
• Economics and risk

Best combo for decision-making

If I were narrowing it down to the most useful mix, I’d start with:

1. SARE
2. Practical Farmers of Iowa
3. Your state Extension service
4. No-Till Farmer
5. USDA NRCS soil health materials

That combination gives you:

• research-based guidance,
• on-farm trial data,
• regional applicability,
• and real operational detail.

If you want, I can also give you a shortlist by region (e.g., Midwest, Plains, Southeast) or a comparison table of cover crop species and rotation pros/cons for large-scale row-crop farms.
