|Title of the thesis:||Plants Spectral Characteristics Displays using of the Earth Remote Sensing Methods|
|For a long time, agriculture has been an important sector of our society. However, the quality of agricultural production depends on several factors. Climate changes, limited rainfalls, storm rainfalls, increasing temperature differences, water and soil quality, technological processes, the use of fertilizers and many other factors affect biomass production. In agriculture, remote sensing of the Earth is widely used, thanks to which we can determine the quality of vegetation cover, possible damages to the crop, but also analyze the amount of water in cultivated area. The scanned plants are represented by specific reflectivity in individual bands of electromagnetic radiation. Visible radiation provides information about the condition of the photosynthetic apparatus and infrared spectrum about the amount of biomass and the health of the flora. The aim of the thesis was to prepare an overview of the literature about addressed issues. The practical goal was to use a spectrometer to study reflection directly on the leaves of sunflower in selected spectral bands based on water level in plants. Also observe changes in reflection depending on the gradual drying of plants grown in substrate, compost, and their combinations in different proportions. In general, the highest values of reflection were shown by the samples in the combination of substrate + compost in a ratio of 1:3. The measured reflection in the visible spectrum did not change significantly depending on the decrease of humidity. The changes were more significant when measured in the infrared spectrum. We observed differences in reflection even after application of biochar in samples, which is characterized by beneficial effects on water absorption, soil fertility and plant growth. In 6this case, there was a visible deviation of reflection and drying of the samples.|
