DTN (Digital Tornado Network, owned by TeleCommunication Systems) has been the dominant ag market data provider for 30+ years. GrainBrief is a purpose-built fertilizer price intelligence tool launched in 2026. Here is how they compare for the specific use case of fertilizer price tracking and buy/hold decision support.
| Feature | GrainBrief | DTN |
|---|---|---|
| Fertilizer price tracking | Yes — 9 inputs, 50 states | Yes — broad but requires Pro plan |
| Buy / hold / negotiate signal | Weekly automated signal | No automated signal — raw data only |
| Price per month (entry) | $29/month | $150–$400+/month (suite) |
| Setup complexity | Self-serve, no sales call | Sales-qualified, contract required |
| Data sources | USDA AMS, FRED, EIA (public) | DTN proprietary + public |
| State-level price pages | 450 pages, 50 states | Available but paywalled |
| Mobile alerts | Email alerts included | Available at higher tiers |
If you need weather, grain futures, and equipment data in one platform, DTN's breadth is unmatched. If fertilizer price intelligence and buy/hold signals are your primary need, GrainBrief delivers more actionable output at 10–15% of the cost. Most independent farmers do not need the full DTN suite.
DTN does provide fertilizer market data, but it is bundled into a broader agricultural data platform that starts at $150+/month. The data is raw — there is no automated buy/hold signal for individual inputs. GrainBrief focuses specifically on fertilizer price intelligence and ships a weekly decision signal.
GrainBrief uses USDA AMS, FRED (Federal Reserve Bank of St. Louis), and EIA data — the same public datasets DTN incorporates. DTN supplements with proprietary survey data from dealers. For most farmers, USDA AMS weekly price surveys are sufficient and are the benchmark most agronomists and co-ops reference.
Weekly buy/hold/negotiate signals for every major input. No manual spreadsheets. No paywalled databases. Starts at $29/month.
