“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.”
