By method of historical-scientific analysis with engaging before inaccessible archival deeds and materials they restored life and victories of M.O.

Tiulenev’s development and practical recommendations, first of all in 20–30 of the past century, the organizational becoming of system of scientific provision of drainage ameliorations in UkSSR took place, as well as its saving during German occupation in 1941–1943, and ascending gradient in 50–60 of XXth century. Protruding role is proved of M.O. Tiulenev in foundation of Kazorovitskyi research and development melioration station (1922), Sagaydatska irrigation experimental station (1922), Sulske paludal field (1930), and restoring activity of Rudnia-Radovelska paludal experimental station (1923) and Panfilo-Yagotin paludal experimental base (1935), and also becoming of activity of Minsk paludal experimental station (1911).
