In the 50­-90 scientific research concerning improvement in diagnostic of waterlogged soils in Poland were carried out during drainage melioration of arable soils. This study was focused on morphological features of soils which help to forecast soil anoxia. This evaluation method was widely used and qualitative in nature. Its principle was the basis of new branch of water melioration, directed to support oxygen balance in soil. In the result parameters of soil redox optimal for Poland were defined.
