An agricultural multi-rotor drone is positioned centrally on a field of green grass and low-lying vegetation in Ruska Bela, Bulgaria. The drone is predominantly black with red accents on its arms and features a white liquid tank mounted underneath its main body. Four visible propeller blades are black. A bright green hose, with sections striped in yellow, is connected to the drone and extends diagonally across the grass towards the lower-right corner of the frame. To the left of the drone, a pile of cut dry tree branches is visible on the ground. In the background, a line of leafless deciduous trees stands against the horizon. The sky is partly cloudy, displaying a mix of grey and white stratocumulus clouds with patches of blue. A small, light-colored object is partially visible within the grass in the lower-left foreground. No individuals are present in the scene.
