In the context of the recent global climate changes, reflected by the extreme phenomena (prolonged droughts, torrential rains, storms, contradictory water regime), it is of particular importance to identify their repercussions on the crop growing. The paper is focused on the possibilities of identification, by modern techniques, of the areas with different legumes and oleaginous species affected by hydric stress, due to prolonged drought or periodic water stagnation. The authors present in detail several useful observations resulted from taking over and processing images, obtained by the latest generation techniques. By using modern devices for taking pictures at certain heights such as performance drones equipped with digital cameras and with high resolution, are obtained images with whole surface of cultivated crops. Such images cannot be obtained by conventional means at the ground level. The use of the drones in such situations, in comparison with avio means, consists in considerably diminished costs, extensive handling possibilities and the acquisition of detailed images of areas of interest such as so called hot spots, operability and flexibility. The images accumulated from several locations with different crop species reveal the possibility of identifying in the early stages of negative processes due to the climatic factors that determine the degradation of the soil resources, the growing stagnation of the plants and implicitly the decrease of the quality of the obtained production. Identifying these processes is important for applying measures to mitigate negative effects on cultivated plants or adjusting pallet cultivation technologies.
