Loosening the top layer of the roll.
After plowing, the field is not yet sufficiently prepared for this, so that you can sow or plant. The surface of the plowed field is uneven, dug up with furrows and large lumps of soil. Such a surface requires leveling, and the lumps - crumbles. During plowing, weed roots and seeds were covered. Many of them start to sprout again. The aim of the tilling tools is therefore, among other things, to extract the roots and runners, e.g. perzu, and destroy any germinating weeds.
The furrows created after the pre-winter plowing accumulated a lot of water, which evaporates from the soil in the spring. This is a very unfavorable phenomenon and it should be prevented precisely by destroying the capillary system with treatments. For this purpose, shallow loosening of the upper layer of the roll is performed, thanks to which a layer is created that insulates the moisture contained in the soil. On some soils, if sowing is done on freshly plowed soil, it must be rolled beforehand, which will accelerate subsidence of the soil and facilitate moisture soaking under its surface. Due to the variety of tasks of the treatments, many different tools are used, such as: dragons, Harrow, cultivators, rippers and rollers.
