ABSTRACT

The article presents the results of prognostic simulation which refers to the momentary dose of liquid applied by the field sprayer with an automatic pressure control. The simulation used, registered at frequency of 1 Hz, data regarding speed, the direction of movement and the position coordinates of the sprayer during the process of plant protection on field. Based on the results, it was found that while ride parallel along the straight technological paths about half of the surface of the field is covered with a liquid in an amount different from the intended at least ± 5%; and, furthermore, that should be strictly avoided to twist during working passes, because the momentary liquid dose may even exceed many times the manufacturers' recommendations of pesticides and liquid fertilizers.
