ABSTRACT

The article deals with the ecological and economically balanced functioning of combined drainage systems on heavy soils of the Novgorod region. The water-air regime of the drained lands and the parameters influencing it (a drainage drain, a level of ground waters) is considered as an ecological indicator, and economic – increase of productivity of lands. The studies were carried out at the experimental experimental field, drained by closed drainage with backfilling of the drainage trench of the sand-gravel mixture to the arable horizon (control), two-tier drainage and a combination of with deep loosening. The analysis of the results of the study showed that the experimental combined drainage system was set aside 88% more runoff compared with control; in the excessively wet growing season (25% probability of precipitation), the system of two-tier drainage there was the lowest level of groundwater and soil moisture; the effect of deep loosening began to decrease by 3 year of operation of combined drainage, so it is recommended to carry out deep loosening on loamy soils every 3 years; from the ecological and economic point of view the most balanced option is the combined two-tier drainage.
