The main factors influencing the formation of an undesirable phenomenon in the soil, the so-called plow sole, are named. The analysis of domestic and foreign modern methods and means of determination and measurement of soil hardness, starting from penetrometers and ending with soil scanners is presented. The issue of soil hardness was and is relevant, because it depends on the formation of yields and, accordingly, the profit of farmers. Thus, there is an urgent task of improving methods and means of measuring soil hardness. The question of developing a cheaper method, in contrast to soil scanners, to determine the plow sole, but no less effective than them. ER -
