Role of Higher Aquatic Vegetation in the Accumulation of Organic and Biogenic Substances in Inland Waters (K Poli Bisshei Vodnoi Rastitel'nosti V Nakoplenii Organcheskikh i Biogenn'ikh Veshestv v Vodoemakh),
Abstract
It is established experimentally that higher water vegetation after dying off and mineralization can serve as one of the main sources of accumulating organic and biogenic substances in a water medium. The quantity of saprophytic microorganisms and rate of accumulation organic and biogenic substances are the highest in the first ten-day periods of vegetation contact with water. To the second month the amount of biochemically constant organic substances and the ratio C:N increase, the ratio of ammonium nitrogen to organic one and the quantity of saprophytic, proteolytic, anaerobic, cellulose and ammonificating bacteria decrease. During this peroid the nitrification intensity grows. At maximum output of organic and biogenic substances the content of organic nitrogen and carbon is 1.3 to 10 times and that of mineral derivative of nitrogen and phosphorus is 11 to 70 times as high as the background one.
