| Popis: |
In this study particular attention has been paid to the solving of neutralization problems in Finnish lakes with two special characteristics: the typically high humus content, and the 4–6 months for which the watercourses are covered by ice. The effect of organic content on the specific neutralization demand was studied by means of laboratory experiments. The specific neutralization demand increases with increasing organic content. Laboratory tests were also carried out to compare three different liming methods, the results then being applied to the neutralization of three small lakes. Liming of the lake ice proved to be almost as efficient a method as wet application, and distinctly better than dry application. Cost assessments were also made to compare the different liming methods. Finnish neutralization practice and lake liming projects have also briefly been described. |
