Monitoring the condition of rapeseed plants using UAVs to determine the NDVI index
Kelc, Damijan, agronom ...
Various remote sensing systems are used to monitor the condition of rapeseed plants from sowing to harvest. The possibilities of using drones to determine the NDVI index were studied. In the ...experimental field, three flights during the oilseed rape growing season were performed on the property of Jeruzalem SAT d.d. at GERK Loperšice levo, which is 18.4 ha in size and is located between Ormož and Središče ob Dravi. We used Phantom 4 drone in combination with Sequoia + multispectral camera to capture photographs, which were processed using PIX4D Fields software. Photographs were combined into an orthomosaic. The values of the NDVI index were determined. Measurements confirmed the conclusions of other studies. The values obtained from the drone images were compared with the images from the Landsat-8 satellite. Our drone shots are much better and more convenient. The images are important for targeted selective fertilization and application of reduced amounts of phytopharmacy protection products. Savings and contribution to environmental protection are very important.
