Dehydration of agricultural lands is one of many methods of natural environment creation. Many ways of doing it, which may be distinguished, depend on a number of physicochemical characteristics of soil, climate conditions on particular area and eff ect that is desirable to achieve, which in turn depends directly on agricultural operations and, in particular, on the type of cultivated plants. Despite from what has been written, the aim of designing a proper drainage system is by all means an improvement of the agricultural ground quality through enhancing ground aeration. It results from the structure of the soil environment that is always built with tree essential phases – constant, liquid (soil water) and vapour (soil air), which should occur in a strict portions, so that the proper functionality of the ground could be enabled. The constant phase is mainly built from bedrock and spin-off minerals, as well as organic compounds of diverse volume. They percentage in the ground allows to determine its granulometric composition, which has a crucial infl uence on soil characteristics by determining its aeration and hydration. To the grounds of both best aeration and least hydration are rated light formations which contain a signifi cant amount of the sand fraction. In a contrary, heavy soils containing big amounts of ash and clay fractions belong to best hydrated, however, less hydrated formations. As a result, the best features are shown by soils of the intermediate composition, so called medium soils, such as a light loam [3]. Using a drainage system or other methods leads to remediation of the disproportion between particular soil phases, through decreasing aeration of heavy grounds, which contain a great portion of water. The result will be to achieve the correct, aggregate structure of the ground and maintain the proper level of ground water, and eventually to improve both the quality and the productivity of the ground.
