FIELD: agriculture. ^ SUBSTANCE: method includes dosed supply of fertiliser under cultivator leg. In front of cultivator leg hardness of soil is continuously measured on its undersurface level. Depending on variation of soil hardness, dose of fertiliser supplied under cultivator leg is varied. Device comprises frame, ripper, stand, strain gage link, metering complex, cultivator leg, hopper for fertilisers and fertiliser funnel. Ripper is installed on lower arm of double-arm lever, which is hingedly arranged relative to frame. Stand is rigidly installed relative to frame. Strain gage link is connected to upper arm of double-arm lever and stand, and is connected to metering complex. Cultivator leg is fixed on frame behined ripper. Fertiliser funnel is connected under cultivator leg and is communicated to hopper via batcher. Batcher includes actuating element in the form of gate with electromechanical drive. Metering complex is an analog-digital/digital-analog conveter ADC/DAC connected to notebook and to electromechanical drive of batcher gate. On frame there is a slider installed with the possibility of longitudinal motion relative to travel of moving and fixing device. On slider there are hinged and rigid joints of double-arm lever and stand relative to frame. ^ EFFECT: invention provides for coordination of fertiliser dose supplied under cultivator leg with fertility of parcel ripped at the moment by cultivator leg. ^ 2 cl, 1 dwg |
