How a Crop Tells You It Is Stressed Before You Can See It
A crop signals stress in reflected light before one person walking the field can see it. Water shortage and disease change how leaves reflect near-infrared, and that shift appears days ahead of any visible discolouration. Scouting on foot samples a few points; the change is happening across the whole field.
An explainer in this category exists because the buyer already accepts that scouting is imperfect and does not understand what a drone is actually measuring. Selling imagery without explaining reflectance produces a grower who thinks they are buying aerial photographs. What belongs in the file rather than the frames is the interface entirely: dashboards, map layers, and export formats belong in the product video, and showing them here replaces the mechanism with a tour.
The mechanism is set out across seven scenes: one on what the eye can and cannot detect in a canopy, two on how leaves reflect light differently when stressed, one on why an index rather than a picture is the output, one on flight coverage against foot sampling, one on what a flagged zone means and does not mean, and one on the ground-truthing step that stays with the agronomist.
