The present invention relates to a soil cultivation device with a rotating roller implement, comprising a shaft rotating around an essentially horizontal axis, with a multitude of crescent shaped spring elements arranged over the entire circumference and width of said shaft, with the spring elements each being fastened to the shaft at one end section, and being bent in the direction of their other, free end section before extending arcuately along a circumferential segment of an outer circumference or a quasi-circular outline of the roller implement, with said circumference or outline being nearly coaxial to the rotating shaft. At least some of the spring elements comprise, in at least one area with a flat cross-section, a defined elastic pliability, and comprise in at least one section in the direction toward the free end and/or in the area of their circumferential segment a profiled cross-section of a defined bending stiffness.
