Phosphorus availability in low P-soils is primarily controlled by soil processes that are subject to seasonal fluc- tuation. There is evidence that summer drought causing low fen-water levels induces temporal high P-availability. We investigate here

Nitrogen, phosphorus and potassium were supplied to some Belgian fens of varying nutrient status and productivity. Plant growth in the lowest productive fen with a species-rich Caricion davallianae vegetation was strongly P-limited. N was ineffective

Intact rich fen soil cores with controlled water levels near the surface were installed in an open greenhouse. To simulate short term summer drought, water levels were lowered (20 cm) after two weeks in half of the cores (experimental cores) and rema
