“…It is known that to ensure objective calculation results, all components of the water balance equation must comply with the principle of equal accuracy. Meanwhile, the analysis of special literature and previously performed field experiments [3][4][5][6][7][8][9] shows that when calculating the water balance of ameliorated soil, the soil runoff is the least justified value in comparison with other elements of the water balance. This is confirmed by the fact that in most calculation methods the value of soil runoff is calculated as the excess of the current moisture reserves of the soil (Wi, mm) over the upper limit of their regulation, equal to the lowest moisture capacity (Wнв, mm).…”

The water regime on the reclaimed lands changes significantly during the year, and its possible change must be established or predicted in advance at the project stage. From the main characteristics of the water regime of soil, it is possible to reliably predict changes in moisture reserves and, worse, the dynamics of groundwater levels. Prediction of changes in moisture reserves in soil is carried out using “water balance calculations”. The results of long-term field research have shown that the main factors causing surface runoff are: the amount and intensity of precipitation, the initial moisture content of the upper soil layers, the slope and condition (agricultural use) of the site surface. The feasibility of using a variable runoff boundary in calculating the water balance of ameliorated soil is shown. The results of field experiments on the study of surface runoff in conditions of loamy soil are presented. Two-factor dependences of the daily runoff from precipitation and soil moisture have been obtained in case of its various agricultural uses.

“…The soil and climatic conditions of the Republic of Belarus do not allow intensive farming due to waterlogging on an area of about 8 million hectares (more than 40% of the territory) [8]. In this regard, drainage reclamation systems have been of fundamental importance for the development of agricultural production in the Republic of Belarus for more than 120 years [9].…”

Studies conducted to study the effectiveness of the introduction of micro-deposits of silt into the soil as part of organo-mineral fertilizers in combination with conventional mineral and organic fertilizers have shown that the accumulation of nutrients in the soil. The best options affecting agronomic indicators were application doses in the amount of 20-25 t/ha. Taking into account more effective results for use in production, it is recommended in these soil-hydrogeological conditions to apply silt deposits at a dose of 25 t/ha, cattle manure 10 t/ha and the introduction of mineral fertilizers at a dose of – N88P43K46.
