Rollers for soil compaction.
The role of the rollers is to compact the soil in order to reduce its porosity and to crush the lumps on its surface. When leveling the surface, the rollers crush or press into the soil these dried lumps, which have not been broken by previous cultivation treatments. The pressed lumps soak up moisture and soften. Depending on the structure of the roller, its operation may give the desired effect directly on the surface of the roll or at a certain depth. Compaction of the soil causes the compaction of its particles, which facilitates soaking under the surface of the role of moisture, which is very necessary for the germinating seeds. Therefore, rolling is a procedure that is carried out before sowing or planting, and sometimes also right after these activities.
