Factors Controlling the Seasonal Variation of Nitrate in Lake Erken |
|
| Authors: | Bengt Boströ m |
| Abstract: | The seasonal variation of the nitrate concentration in the mesotrophic Lake Erken is markedly regular and shows some important differences compared with that of phosphate. Nitrification occurs mainly at the sediment surface. Nitrate accumulates when the nitrification-denitrification sequence is broken at a time when the nitrate assimilation is small. This occurs in Lake Erken during autumn turnover. |
