METHOD AND DEVICE FOR INTRODUCING LIQUID AND SUSPENDED FERTILIZER SIMULTANEOUSLY WITH PLOUGHING Russian patent published in 1997 - IPC

FIELD: agricultural technology. SUBSTANCE: improved distribution of fertilizer in soil layer is achieved due to its distribution in strips simultaneously with ploughing through working width of ploughing unit. Ploughing is performed by multilayer (multidepth) method and fertilizer is distributed on surface of each layer before its undercutting and displacement. Device for realization of method is embodied in the form of semi-trailer and has vessel for fertilizer, system for delivering fertilizer from vessel to jets of ploughing member which is represented by multidepth share-mouldboard plough in which jets are installed in front of each body. Distributing hole of jet for each subsequent body is located above cutting edge of preceding share. EFFECT: high efficiency. 12 cl, 6 dwg
