Abstract: Weed management still remains one of the biggest problems in agriculture, especially in organic farming, where usage of synthetic herbicides is prohibited. Ploughing is considered as best way to solve this issue. Topsoil overturn angle is very important ploughing parameter, as it determines incorporation of plant residues and weed seeds into soil. There are several different plough types depending on their construction, work abilities and topsoil overturn angle. As a control treatment the most common plough's in Lithuania overturning angle - 135 degrees - was taken. Generally it overturns soil not efficiently enough to achieve qualitative weed control in non-chemical weed control system. Four different soil overturn angles were studied in model experiment carried out at the Experimental Station of Lithuanian University of Agriculture during 2009-2010. The smallest amount of weed seeds after overturn in 2009 within 0-20 cm soil layer was found in no tillage treatment. The top soil layer (0-5 cm) had least weed seed amount at turning soil by 135 and 180 degrees. The highest weed taken with spring barley crop at hard stage of maturity number and mass was found in treatment where soil had been overturned by 180 degrees
