COMBINED TOOLS FOR DEEP LOOSENING SOIL WITH FERTILISER APPLICATION Russian patent published in 2013 - IPC A01B49/04 A01B13/08 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery. The tool comprises a frame with racks fixed on it, a tank for fertilisers. The racks have the vertical part with the inclined right- and left-sided blades and the fertilising tubes with the sprayer located on the rear side. The racks are mounted on the frame in two rows, the fertilising tubes are mounted on the first row racks. The diameter of the tubes is smaller than the width of the racks. The vertical parts of the second row of the racks have smaller coverage to avoid damage to the walls of the slots and create an additional resistance. The sprayers are made with the ability to spray fertiliser in both directions. The desired depth of spraying of the fertilisers is set by moving the fertilising tube along the rack up or down, providing spraying of the fertiliser in the center of the crown of the roots of cultivated plants, depending on the depth of location of the basic mass of the root system.

EFFECT: constructive implementation enables to reduce the traction resistance of the tool and to provide per a single pass of the tool the deep tillage and application of fertilisers in the soil avoiding the negative impact on the environmental condition.
