Monitoring of soybean growth stages using an unmanned aerial vehicle (UAV)

Monitoring of crop properties using UAV is a novel procedure in agricultural practice, allowing the detection of anomalies and the adjustment of crop management. In this research, five cyclic imaging repetitions were conducted for soybean agricultural parcel located in Donji Miholjac. Monitored soybean growth stages were a reference stage before sowing, fourth trifoliolate, beginning pod and beginning maturity stage. Images collected in the field were processed by Structure-from- Motion algorithm for the creation of digital orthophoto. Four complementary vegetation indices calculated from red, green and blue spectral channels of digital orthophoto were used for the interpretation of crop properties. The low-cost and effectiveness of UAV in crop monitoring showed potential for implementation in agricultural practice.
