Abstract:

Summer zooplankton of four lakes was studied for 11 years. In the years 1971-1974 the lakes were treated with inorganic fertilizers (NPK) and then the fertilization was stopped. Significant changes indicating a higher trophic state could be seen in the years of inorganic fertilization in lakes with an initially low pH. The ceasing of fertilization resulted in an insignificant drop of the trophic state of the study lakes, the stronger the zooplankton initial response to inorganic fertilization, the greater the fall of the trophic state. This did not, however, cause the summer zooplankton communities to recover an abundance and structure level similar to that recorded in the control year (1970).
