The article presents an initial assessment of the new regulatory system of a spray dose adjustment system for field sprayers. In contrast to traditional sprayers, the proposed solution incorporates triple interlocked with diversified liquid expense nozzles controlled based on the dose adjustment process utilizing the forward and angular velocities of the machine. The adjustment system was tested using data gathered from monitoring the movement of a sprayer performing chemical plant preservation. The results prove that the system enables a substantial improvement in the surface distribution of the spray dose. Compared to the aforementioned traditional sprayer, where only 57.2% of measuring points have shown the spray dose being within 80-120% of nominal range, using the proposed solution the proper dose constituted 93.6% of all results.
