FIELD: agriculture.
SUBSTANCE: device has unmovable bath filled with the soil layer. The movable frame is rigidly secured to the horizontal guides of the bath and provided with the pivotally connected lever with weights. The rectangular die provided with lugs is secured to the lever through the pivot and axle of changeable length. The frame is provided with a strain-measuring complex connected to the oscilloscope via an amplifier and made of movable sensor of vertical deformation of the soil layer secured to the die through the tie and mounted for permitting horizontal movement along the guide.
EFFECT: enhanced accuracy.
