FIELD: agriculture.
SUBSTANCE: farmer buys the essential nutrients that are mixed together during delivery to the field. The pneumatic trailer having a plurality of compartments is selected according to the amount of essential nutrients and/or grain delivered. The dosing units connected with each compartment control the rate at which the product is delivered. The operator defines the required mixture of fertiliser and determines each of the essential nutrients loaded into the pneumatic trailer. The control unit generates control output signals to each dosing unit to control the rate at which the product is delivered according to the required mixture of fertilisers.
EFFECT: farmer can buy and store essential nutrients rather than different mixtures of fertilisers, and to create multiple mixtures defined by the user, if necessary, according to the region and type of grains sown.
