abstract: The first part of the present review of literature concerning formation and flow of gases in a soil under limited oxygenation, induced by high water content (saturation by precipitation water or by wastewater). The review of literature is also connected with transformation of some elements such as: C, N, Mn, Fe, S and P in relation to oxygen availability, the main electron acceptor in redox reactions which take place in soil environment. The essential objective of the paper was to analyse the plant response under limited oxygenation in relation to such parameters as: microdiffusion of oxygen (ODR) and redox potential (Eh). The results of our investigations in experimental fields, after multiple flooding of soil with wastewater after II step of purification, when willow, rape, mays and grass mixture was planted are presented. Dynamic of emitted gases from mackpeat soil with and without tested plant in relation to oxygenation state, after waste water introduction at different vegetation period and season is presented. It was stated that soils treated with waste water showed significant increase in emission of gases: methane from 0.01 to 0.486 dm3 m-2 h-1, carbon dioxide to the level of 2.3; 10.85 and 10.15 dm3 m-2 h-1 as well as ethylene up to 0.003 dm3 m-2 h-1. Gas emission was correlated with rhizosphere thermal conditions and was multiplied at temperature above 10°C. Cultivation of plants (one-year as well as multiyear in anaerobic soil conditions) shows a significant emission of greenhouse gases which exceeded many times (2-200 times) emission from soil surface non covered by plants. The highest greenhouse gases flow occurred in the case of rape plants.
