Summary. A trial programme on liming of acidified lakes and watercourses in Sweden was conducted during the period to The positive experiences acquired resulted in the initiation of a large-scale operative activity from onwards, which is mainly financed by governmental by: 8.

Sphagnum mosses decline sharply, with a consequent reduction in biomass in the most acidified lakes, and colonization of surfaces previously covered by Sphagnum is usually slow. Proliferation of alternate water milfoil (Myriophyllum alterniflorum) has been observed in a number of shallow lakes after repeated liming by: 8.

Sudbury, Bryn Harris. Although subaqueous oxidation of pyrite by Fe3+ is probably a common (and usually overlooked) phenomenon in acidic lakes, this process is not expected to be important in pit lakes with near-neutral or alkaline pH, mainly because the solubility of Fe3+ is so low at pH > 4.

Since. from base flow to high flow, and in the western Adirondack region, the percentage of acidified streams at base flow ranged from 19% to 35% and increased to 66% at high flow.

Stream sampling also serves as a useful indicator of acidified soils due to the strong linkage between soil chemistry and stream chemistry during high flows.
