Corn at V6, pale yellow stripes between the veins on the newer leaves. Sandy loam, Grundy County, Iowa.
Photo attached · Field “North 80” · May 28
This pattern on young leaves after a cool, wet May on sandy soil points to sulfur deficiency rather than nitrogen.
- 1.Confirm with a tissue test on the youngest collared leaves (S below 0.15% confirms it).
- 2.Apply 15–20 lb S/ac as ammonium sulfate; side-dress now so it reaches the roots before V10.
- 3.Next spring, put sulfur in the starter on this field — sandy, low-organic-matter soils run short every year.

Illustrative answers. In the app Norman asks for your location and field history first and cites the label it used.
One advisor for the whole season
Everything an agronomist would help you with, in one place — from the rotation plan in February to the last entry in the field diary after harvest.
Before planting
- Rotation planner
Next crops for every field, with family rules and herbicide carry-over taken into account.
- Fertilizer calculator
Rates by crop, soil test and yield goal, in the units you use.
- Documents
Upload a soil test, a label or a scouting report as PDF — Norman reads it and answers from it.
In the field
- Photo diagnosis
Disease, pest or deficiency from a phone photo, with a treatment plan for your crop and stage.
- Agronomy advice
Any question, any hour. Recommendations use products registered in your state or province.
- Field weather
Current conditions and the forecast for each field, not for the nearest city.
Records
- Field map
Boundaries, crops and history on a map, with satellite vegetation index for each field.
- Work calendar
Sowing, spraying and harvest with reminders, and a diary of what was done on each field.

Advice that fits the farm, not the average farm
Norman knows where you are. The same question gets a different answer in Iowa, Ontario and Saskatchewan — because the labels, the zones and the units are different.
- Registered products only
- Recommendations come from labels registered in your state (EPA) or province (PMRA), with PHI and re-entry intervals.
- Your units
- Bushels and pounds per acre, °F and inches — or metric for Canadian farms. No conversions on your side.
- Every field is its own place
- Weather, satellite vegetation index, soil notes and history are kept per field, and the advice uses them.
- Your data stays yours
- Fields, photos and conversations belong to your account. No advertising profiles are built from them.
