Ask it like you’d ask an agronomist.
Example questions Fieldhand AI answers today, and what produces each answer. Ask in your own words; these are starting points.
- ComputedA software tool computes this from a published equation or guideline table.
- EstimatedAn agronomic estimate with a confidence band, labeled as one.
- ActionFieldhand drafts it and asks before anything is sent or ordered.
Will this application pay for itself?
Answer a few questions and Fieldhand’s ROI engine, the same one the agent uses, prices the application: cost, the yield gain it needs to break even, and the expected gain where a published response model applies.
- No AI writes these numbers. The engine computes them from your inputs and published research, and shows its sources.
- Corn nitrogen in Illinois, Indiana, Michigan, Minnesota, Ohio and Wisconsin uses the university MRTN response curves. Phosphorus and potassium show the published odds of any response. Elsewhere you get cost and break-even, not an invented gain.
- Suggested prices are Iowa averages. Outside the US, enter your own prices in your currency.
Read a soil test
- Computed
“Is 28 ppm Bray-1 phosphorus low for corn on this field?”
Rated against the regional guideline for the field and the lab’s method, with the guideline named.
- Computed
“My soil test says pH 5.8 and CEC 14. What stands out?”
Each value is rated against the guideline the account resolves to; the answer names which one.
- Computed
“What is the base saturation on this field, and is magnesium in balance?”
Base saturation is computed from the lab’s exchangeable cations, then rated against the regional guideline.
Convert and calculate
- Computed
“What is 60 kg/ha of K₂O as elemental K?”
Oxide and unit conversions use fixed factors, such as K₂O = 1.205 × K and P₂O₅ = 2.291 × P.
- Computed
“How much P₂O₅ will a 200 bu/ac corn crop remove?”
Crop removal comes from a removal-coefficient table, using the yield you state or the field’s recorded yield.
- Computed
“How much lime do I need to take pH from 5.8 to 6.5 with a product rated at 90% ECCE?”
The lime requirement is adjusted for the product’s ECCE and the incorporation depth.
Ask what if
- Computed
“What if I credit 4,000 gal/ac of hog manure at 25 lb P₂O₅ per 1,000 gal?”
The credit is subtracted from the target rate, and the remaining commercial rate is recalculated.
- Computed
“What if my potassium test had come back 20% higher?”
The value is re-rated against the same guideline, so you can see whether the call would change.
- Estimated
“What if I put on 40 more lb of nitrogen in zone 2?”
An agronomic response-curve estimate, per zone, with a confidence band. It is labeled as an estimate, not a calculation.
Zones or one rate
- Computed
“Should this field get variable-rate lime, or one rate?”
Zones are recommended only when they beat a single field-average rate on held-out samples.
- Computed
“How sure are you about this phosphorus map?”
Each value says whether it was measured or predicted, with its confidence and where it came from.
- Computed
“Do I need to re-test before fall?”
Checks the age of the field’s soil tests and whether new samples would change a decision, then drafts a sampling plan.
Get it done
- Action
“Write a lime prescription for this field and export a shapefile.”
Drafted from the field’s soil tests and reviewed with you before it is shared or exported.
- Action
“Make a soil report for this field and share it with my agronomist.”
Generates the PDF report and creates a share link that expires and can be revoked. Fieldhand asks before sending.
- Action
“Order a soil test for my north fields.”
Emails the order to the lab you choose, with the sample locations attached. Fieldhand asks first.
