Eutrofhication, nature management and the role of potassium

In The Netherlands the process of eutrophication often results in hypertrophy, the aspects of which are presented in an outline. Emphasis is given to the evaluation of existing trophic situations in relation to species diversity, biomass, and effect of accelerated eutrophication compared to natural eutrophication. The possible role of potassium in eutrophication is mentioned.
