NDVI, made simple
If you can read a traffic light, you can read NDVI.
NDVI stands for Normalized Difference Vegetation Index. In plain language, it is a satellite-based color map that shows differences in crop vigor across your field.
Greener zones
Usually show stronger vegetation activity compared with the rest of the field.
Yellow or orange zones
Show weaker or changing areas that may be worth checking first.
Compare different dates
See whether field conditions appear to be improving, declining, or staying stable.
NDVI points you to where to inspect first. Field scouting is still needed to confirm whether the cause is water, nutrients, pests, disease, or something else.
Your farm, organized
One account for every field you manage.
Draw or import field boundaries, keep an unlimited number of fields together, and open the details you need without searching through paper maps or old screenshots.
Check area and weather quickly
See farm information and weather in the same workspace before deciding when and where to go.

Draw or import boundaries
Add as many fields as you need and let the system calculate area.
Choose an available date
Open the satellite crop-growth layer and review variation across the field.
Check the right zones first
Use the map to focus field scouting instead of walking every acre blindly.
See change over time
Compare dates, not just colors.
A single image is useful. A comparison is better. Put two dates side by side to see which zones changed and decide where to inspect next.
Spot zones that look weaker than the rest of the field.
See whether crop vigor appears to improve after an action.
Use the map to plan a more focused field visit.
Your fields go with you
Check field information from the office, truck, or field edge.
Open FieldFusion on your computer or phone to keep field boundaries, area, weather, and crop-growth information close at hand.
Review fields without carrying paper maps.
Check weather before sending people or equipment out.
Use NDVI to decide which zones deserve attention first.
From insight to action
When you are ready, turn NDVI differences into a field-ready prescription map.
Use crop-growth zones to plan different rates for fertilizer, seed, or spray, then export a prescription file for compatible equipment. The goal is simple: put inputs where they are needed instead of treating every part of the field the same.

Good to know
Questions farmers often ask about NDVI.
Does green always mean the crop is healthy?
Not automatically. Greener NDVI usually means stronger vegetation activity relative to other zones. Always use field scouting to confirm the cause.
Can NDVI tell me whether the issue is water, nutrients, or pests?
NDVI highlights differences; it does not diagnose the exact cause by itself. It helps you choose where to inspect first.
Do I need to create every field again each time?
No. Once your field boundaries are saved, you can return to the same field records and available imagery from your account.
Can satellite imagery always show a clear result?
Image availability and clarity can vary by date, location, crop cover, and clouds. Compare available dates and combine the map with what you see in the field.
Put every field—and every crop-growth signal—on one map.
