In the territory of Western and Northwestern Serbia, stagnosol soils occupy an area of about 285,000 ha or 15.7%. These soils are of great importance for agricultural production due to their potential fertility, as well as the fact that they are represented mainly on flat plots suitable for the application of mechanized cultivation. The analysis of the water balance revealed large surpluses of water in the colder part of the year (from autumn to spring). The physical properties of the tested soil are unfavorable and characterized by very low permeability of the sub-oric soil horizon. The reason for this is primarily the high content of clay and dust. The consequence of the above is the stagnation of water on the surface and the impossibility of implementing agrotechnical measures in the optimal period. In order to obtain stable yields of these potentially fertile soils, it is necessary to apply complex ameliorative measures, and their effectiveness was confirmed by performing horizontal pipe drainage and supplementary measures of mulching and scattering. The obtained results indicate the necessity of applying the mentioned measures, because they regulate the water regime and achieve economic profit in agricultural production.
