✦ Synopsis
Because the biogeochemical cycles of P and Si in temperate lakes are strongly connected by the dynamics of primary producers, it should be possible to in¯uence the former cycle by causing changes in the latter. It is shown using the mathematical model `Rostherne' that winter levels of ambient Si have a major in¯uence both on spring levels of ambient P and on the summer cyanobacterial maxima. Additions of Si to the lakes could be used for the ®ne regulation of the biogeochemical balance and may prescribe a recipe for improvement of water quality, as well as a new solution to the problem of eutrophication.
