How it works
About Field Signal
Field Signal brings together 25 years of data on weather, soil moisture and plant health, so you can see how different rotations would have done on your field.
What it does
For farmers
For farmers: compares your current rotation with two alternatives (at least one with soybean or peas) and shows, year by year, how each would have done.
For feed buyers
For feed buyers: shows, by commune, the risk of not finding enough harvest, quality risks (aflatoxins, fusarium, harvest rain) and environmental impact.
Everything in the open
Every number shows its source, period, assumptions and confidence next to it.
Data we use
Public data. Resolution shows how big each source's “pixel” is.
| Source | What we use it for | Resolution | Period |
|---|---|---|---|
| NASA POWERNASA data | Heat, rain and air humidity, day by day | 0.5° × 0.625° | 2001–2025 |
| MODIS MOD13Q1NASA data | How green and vigorous the vegetation is (NDVI) | 250 m | 2001–2025 |
| SMAP L4NASA data | Water in the soil, around the roots | 9 km | 2015–2025 |
| SoilGrids 2.0Other public source | Organic carbon, pH and soil texture | 250 m | — |
| EUCROPMAPOther public source | Which crops grow where, for areas per commune | 10 m | 2018 |
| INS AGR110AOther public source | Official county yields, to check the model | — | 2001–2025 |
We use free public data published by NASA and other institutions. NASA is not a partner and does not endorse this tool.
The role of AI
AI does two small, checkable jobs. It does not make decisions for you.
The risk model
A small model estimates the chance of a poor year for each zone and crop, from weather and vegetation signals in the critical periods. We test it by leaving out one year at a time and publish both hits and misses.
The explanations
A language model turns the computed numbers into plain text. It may only use values we computed, in a fixed format.
What it cannot see
- Hail and other short, local weather events.
- Pests and diseases in your field.
- Prices and markets.
- Your field work, hybrids and fertiliser.
- Weather data describe an area tens of kilometres wide, not your exact plot.
About the demo data
In this version the numbers are for demonstration. We mark them clearly as “Demo data” until the real data are connected.
