Crop inspection with drones or satellites determines different levels of crop maturity on the crop. Based on the acquired data optimal time of sowing is planned because the goal is to monitor the plant’s growth: in different wavelengths, different phases of ripening and dying of plant are visible in the later stages. After identification of these stages, together with a farmer, target moisture and protein measurements can be performed; after that, optimal sowing time is planned. Optimal sowing is important because it can result in greater crop maturity and optimal protein content. The latter ensures a higher quality class and a higher purchase price on the market.
