The submitted paper focuses the issue of using a new technology of Near Infrared Reflectance (NIR) sensors in practice for dosing organic fertilizers based on their composition. The HarvestLab 3000 system was tested in a selected enterprise in terms of its usability in practice. In 2021, an experimental plot was selected in a conventional company situated in the southern part of Czech Republic. The HarvestLab 3000 system with the NIR technology was used for the variable (VR) dosage of digestate as a basic fertiliz...

The presented paper deals with the targeted application of pre-emergent herbicides. The field experiment was established in 2022 and 2023; two plots sized 26 ha and 30 ha were selected and the accuracy of the application was tested. There were local outbreaks of weeds on selected plots of land, which had to be eliminated before sowing the main crop - soybeans. Both plots were monitored using an unmanned aerial vehicle (UAV) - Mavic 3M with the multispectral camera. After the end of the monitoring, spectral analysi...

The presented paper deals with the issue of assessing the condition of winter wheat (Triticum aestivum L.) stand during its development in the spring period. The field experiment was established in 2020; two plots sized 25 ha and 16 ha were selected with a model plant of winter wheat. In the spring period (BBCH 35 and BBCH 51), both plots were monitored using an unmanned aerial vehicle (UAV) and Sentinel 2 satellites. After the end of the monitoring, spectral analysis of pictures taken was made and a basic NDVI ve...
