Actual questions on the supervision of land reclamation ditches

Natural data has been gathered during survey expeditions while evaluating the state water drainage network in separate Lithuanian regions. In the course of different farming intensity regions for motion in drained soils, the exploitation of water drainage network according to the principle of land tenures has been suggested. The greatest attention to the exploitation of water drainage network should be paid in the places where the arable land is used the most intensively. Five land tenure groups with different water drainage network exploitation levels have been suggested. The main water drainage network, exploitation works situated in different land tenures, have been presented. Tentative recommendations for the improvement of the exploitation works of water drainage network ill drained soils have been presentedVytauto Didžiojo universitetasŽemės ūkio akademij
