USING DISTANT MONITORING METHODS FOR THE CULTIVATION OF CANNABIS
Keywords:technical cannabis, UAV, RGB, nitrous fertilization, plant monitoring, ImageJ
Plant monitoring with the use of distant methods is a way of acquiring the data necessary to operate modern technological systems. The development is moving towards a wider range of observed parts of the wave spectrum. The quality of vegetation and soil monitoring devices is increasing. This is associated with a higher purchase price. Operating costs are also higher. The requirements for the processing of acquired records and their interpretation are also more demanding. The complexity of connecting the obtained data with practical applications in real operation is also increasing. On the contrary, the possibility of using simpler equipment and simple evaluation of the obtained data means lower costs and lower demands on operation and software. The importance of simple monitoring methods also lies in their higher ability to act. Monitoring can be performed at the necessary time and the information obtained can be used immediately for the implementation of agrotechnical interventions. As part of growth experiments on technical cannabis, experimental monitoring using a drone equipped with a standard RGB camera was carried out. It was verified that by employing this fairly easy method, we can differentiate various levels of nitrous fertilization, especially in the red part of the visible spectrum.
