METHOD AND VEHICLE FOR APPLICATION OF AGROCHEMICAL MIXTURE ON FIELD WORKING AREA Russian patent published in 2020 - IPC A01C21/00 A01C23/02 

FIELD: agriculture.

SUBSTANCE: method is implemented using vehicle (3) moving on field (1), and includes: dissipation of solid fertilizer (6) on working area (2) using solid fertilizer device (4) installed on transport vehicle (3). Device (4) is located on rear part of vehicle (3) in direction of movement, and spraying liquid fertilizer additive (7) on working area (2) using field sprayer (5), installed on vehicle (3) is carried out separately from device (4), wherein field sprayer (5) is located on front part of vehicle (3) in direction of movement, and liquid fertilizer additive (7) is protected from coming into contact with surfaces of device (4). Vehicle (3) comprises: solid fertilizer dissipation device (4) mounted on vehicle (3). Method also includes dispersion of fertilizer (6) on working area (2) using device (4) installed on vehicle (3), dispersion of fertilizer additive (7) on working area (2) using field diffuser (5) installed on vehicle (3) separately from device (4), determining the geographical position of vehicle (3) and applying a predetermined amount of fertilizer (6) and fertilizer additive (7), respectively, on field (1) depending on a certain position on field (1). Electromagnetic radiation emitted by plants on working area (2) of field (1) is detected. Detected radiation is analyzed to obtain nitrogen status for each segment of field (1), ratio of fertilizer additive (7) to fertilizer (6) is calculated as a function of the obtained value of nitrogen status for the corresponding segment. Calculated ratio of fertilizer additive (7) to fertilizer (6) is applied to each segment of field (1). Vehicle also comprises: fertilizer dissipation device (4) mounted on vehicle (3), for dissipation of fertilizer (6) on working area (2), field diffuser (5), which is installed on vehicle (3) separately from device (4), control unit (11), which controls intensity of dispersion of fertilizer (6) and fertilizer additive (7) on working area (2), and geographic localization means (10) connected to control unit (11), optical sensor (12) for detecting electromagnetic radiation emitted by the plants on field (1) working area (2), analyzing unit (13) for obtaining nitrogen value computation unit (14) for calculating the ratio of fertilizer additive (7) to fertilizer (6) as a function of the obtained value of nitrogen status for the corresponding segment.

EFFECT: inventions allow regulating the introduction of agrochemical agents.
