Agriculture device for dispensing a liquid

An agricultural device for dispensing a liquid product over a surface to be sprayed, the device comprising:

• at least one boom comprising a longitudinal supply line for transporting the liquid product and a plurality of nozzles that are positioned along the boom, wherein each nozzle is operatively connected to the longitudinal supply line;
• a liquid product supply that is connected to the longitudinal supply line for supplying to the longitudinal supply line the liquid product to be sprayed;
• at least one pressure regulation unit including at least one nozzle controller that is configured for controlling the opening and closing of one or more associated nozzles;
• a speed detector that is configured to measure movement speed of the agricultural device;
• and,
• wherein the at least one pressure regulation unit is configured to calculate nozzle timing data for each associated nozzle, the nozzle timing data at least containing a spraying frequency (Sfreq) and a maximum closing time (Tmax),
• wherein the movement speed is provided to the at least one pressure regulation unit to be included as calculation input for calculation of the nozzle timing data, and
• wherein the at least one nozzle controller is further configured to operate each of the one or more associated nozzles based on the calculated nozzle timing data and wherein the maximum closing time is not exceeded to obtain a homogeneous spraying of the liquid product over a surface of a field to be sprayed.
