Description
Lysimeter experiments were laid out for studying the leaching of nitrogen, calcium, potassium, and phosphorus from different hydromorphic soils. Most of the hydromorphic soils, above all those of low-bog sites, have to be considered as instable open systems from the very beginning of their cultivation. Matter removal well exceeds the amount of matter introduced into these soils. The degree of nutrient leaching in most cases is clearly dependent on the soil humus status. Attention is drawn to the intensive calcium leaching and the low level of nitrogen removal as compared with anpydromorphic soils. The level of potassium leaching is closely correlated with soil texture. Potassium losses were found to be highest in low-bog soils. Losses are at a minimum in hydromorphic soils of loamy-clayey texture. Phosphorus is leached in small quantities only.

Nutrient leaching in hydromorphic grassland soils as established in lysimeters
