The article presents the results of a study of the cationicanionic composition of water extracts, the agrochemical properties of soils of the Kotovschikovsky drainage system in the Znamensky district of the Omsk Region. The analysis of fertility indicators of reclaimed lands revealed their satisfactory condition. Restoration and reconstruction of drainage systems is the basis for increasing agricultural production in the northern districts of the Omsk region, the peat soils of which have relatively high fertility.
