Peculiarities of prevernal moisture saving

Spring is the most important period for workers in the agricultural sector. After abundant snowmelt, the soil is saturated with a large amount of melt water necessary for the formation of friendly and strong future shoots of plants. Soil-a relatively small part of the land, consisting of several layers of different thicknesses, feeding many of its inhabitants, from the smallest microorganisms to humans [1]. The thicker the top layer, the more fertile the soil, and fertility forms the future harvest. Therefore, soil preparation for sowing is one of the most important stages in agriculture [2]. For a short period of time, while the soil is in physical ripeness, it is recommended to close the moisture with harrows, to destroy cracks and crusts on the soil surface, preventing moisture from evaporating from the lower layers under the influence of the rays of the spring scorching sun [3]. Harrows are a very large group of agricultural machines, with different purposes from closing moisture in the spring (tooth harrows), to cutting soil layers before or after plowing (disc harrows), methods of aggregation (trailed, hinged, semi-mounted), and various types of acquisition of working bodies [4]...
