Annotation
The ecosystem of the small, dimictic, and hypertrophic reservoir (Jordan Reservoir, Czech Republic) was studied from March 2001 till March 2004 to evaluate rates at selected pathways in the P-cycle. The rates were inferred from measurement of P mass-balance, sedimentation of seston, and P-release from sediments. A shift between seasonal changes of inflow and outflow P concentrations caused by P accumulation in the hypolimnion and the sediments was demonstrated. An important amount of P was temporally retained at the sediment surface during the summer stratification but a part of it was released back to water during the autumnal mixing, due to pore water „flushing out” and fast organic matter decomposition.
