"The human eye can’t really tell just how well plants have already been fertilised. But robotic eyes..."
“The human eye can’t really tell just how well plants have already been fertilised. But robotic eyes – in other words, multispectral cameras combined with the right software – can assess the nutritional status of the wheat at a glance. To this end, Argento is using the drone to make an aerial photo of the wheatfield – not in the visible spectrum, but in the so-called near-infrared radiation range. This shows the ‘emotional state’ of the plants, as it were. “When plants reflect a lot of near-infrared radiation, then they’re doing well. If they only reflect a little, they are under stress”, says Argento. Plants can get stressed when they are given either too much or too little fertiliser.”
