The effects of liming on water chemistry,hanges in pH, calcium and alkalinity and of secondary effects such as the impact on levels of organic materials, nutrients and trace metals. Data for the evaluation have mainly been drawn from the liming data base (KRUT), which is maintained by Swedish county councils and the Swedish Environmental P

The effects of liming on microbial activity and the decomposition of organic material,influencing the density and activity of micro-organisms and detritivorous invertebrates..Lake liming involves a short and sudden decrease in microbial activity, a “liming shock”. Seen in the longer term, it can indirectly cause an increase in microbial activity and better processing of organic mater

The effects of liming on aquatic flora,ed to epiphytic algae, macrophytes and wetland flora..Lake liming results in an initial decline in the phytoplankton biomass, although this is generally followed by an increase after 1–2 months. The post-liming biomass may be either greater or lesser than it was during the acidification phase and a

The effects of liming on aquatic fauna, well-founded generalizations concerning the effects of treatment on this group of organisms. It is more difficult to make generalizations about lake zooplankton and benthic fauna, which have mainly been studied within the framework of research projects. Benthic faunas in running waters have almost

,Liming strategies and effects: the Lake Gårdsjön case study,greatest individual Swedish effort in the field of acidification and liming research. The majority of studies in the lake itself were concluded in the early 1990s, but some still continue to a limited extent today.

,Liming strategies and effects: the Lake Stora Härsjön case study,fected by acidification at the time. The real documentation of water chemistry and biological conditions in Lake Stora Härsjön began in 1971, when the lake was already severely acidified. The lake was limed in the autumn and winter of 1977/78 and developments since then have been monitored in the fo
