Where Fieldhand works, and how well.
Fieldhand AI works across the United States and Canada, and its depth varies by place. This page says where each part is strongest today and what it does where data is thin.
| What | Coverage today | Strongest in |
|---|---|---|
| Soil-test ratings | Guidelines are built in for Georgia, Illinois, Iowa, Minnesota, Missouri, Nebraska, North Dakota, Oregon, South Dakota, Tennessee, Washington and Wisconsin, the Tri-State region and the US North Central and Southeast, and in Canada for Ontario (OMAFRA Pub 811), Manitoba, Saskatchewan and Alberta. Each answer names the guideline it used. | US states and regions; Ontario, Manitoba, Saskatchewan, Alberta |
| Corn nitrogen economics | Published response curves from the regional Corn Nitrogen Rate Calculator for Illinois, Indiana, Michigan, Minnesota, Ohio and Wisconsin. Elsewhere, Fieldhand gives cost and break-even without inventing a response. | Six US states |
| Market prices | Current USDA cash grain bids for Arkansas, Illinois, Iowa, Mississippi, Nebraska and Tennessee, and hay for Iowa, Montana, Nebraska and South Dakota. Fertilizer prices from USDA’s Iowa report. Each price names its report and date; elsewhere Fieldhand asks for yours. | Selected US states |
| Soil estimates between samples | The soil model was built from lab data in three US regions. Outside them, Fieldhand works from your own soil tests and labels anything estimated. | Three US regions |
| Regional growing zones | Growing zones are described for the United States and Canada, so answers start from the soils and climate where the field is. | US and Canada |
| Language | The app and its answers are in English today. | English |
Coverage as of October 2026. It grows as guidelines, price reports and soil data are added.
Where data is thin
It says so, and asks.
Outside its strongest coverage, Fieldhand does not borrow another region’s numbers.
- It names the guideline behind every rating, so you can check it fits your field.
- Without a local price report, it asks for your prices.
- Without a published response model, it gives cost and break-even and says no model applies.
- It labels every value as measured or estimated.
