Abstract

In periods with a precipitation excess and in many springs the grass yield of old grassland and leys on a heavy river-clay soil was highest on the deepest drained plots. In dry periods the yield decreased with increasing depth of drainage. In the wet periods yields were affected by differences in N supply; in dry periods water supply was the main limiting factor. With grazing, grass growth and utilization were unfavourably affected by high groundwater levels in wet periods. The botanical composition of the sward changed gradually under the effect of groundwater level, but true moisture or drought indicators did not occur.
