Abstract [en]

Data collection for precision agriculture has to be timely, cost effective and have minimum influence on the growing crop. Unmanned aerial vehicles (UAV) may provide unique spatial and temporal field specific information at a low cost. The objective of this project was to test a currently available, low-cost UAV technology and its potential usefulness for collecting information for precision agriculture. This system is the first fixed wing UAV approved for routine flying in uncontrolled airspace in Sweden. Single images and orthophoto mosaics of high-resolution true colour images have been created and compared to field measurements and the paper shows the potential of creating a fully automated aerial mapping system in the future. In this study, focus was set on the occurrence of weeds and N-content variations in wheat. Some comparison between UAV images and the quality of malting barley according to protein content was also made.A limitation in this study was the lack of image acquisition in the NIR spectral range. A NIR-enabled camera option is now available for the UAV-system and future studies of protein registration in grains will be made. Protein content proved to be difficult to measure without data from the NIR-spectral range. Valuable information on nitrogen deficiencies and weed concentration has been collected, indicating an acceptable image quality using the SmartOne UAV for precision agriculture purposes. This system shows great potential to be an important tool for future farm advisors to be able to make frequent, timely inspections of entire fields without any risk of soil compaction.
