Einfluss von grundwasser und trittbelastung auf den prozess der torfmineralisation und die stoffbilanzen: Influence of ground water and footprints on process of peat mineralization and nutrient balances

Abstract

Pasture with burdening on peat-bog done four times a year has more positive effects on the water balance than twice grassland use. The saving of water that has been determined by lysimeters evokes no positive effects on the N-, P-, K- or Ca-balance. Due to the lower depth of the plant roots under lowland bog used for pasture more nutrients were leached into the ground water. The soil compression leads to anaerobic conditions. Therefore the phosphorus becomes more mobile and migrates into the outlet. The effect on the peat mineralization and the nutrient balances was not as clear as assumes, because other parameters like the combination of the vegetation formation and the age of the plants also had a strong influence on the factor. The younger plants from the pastures have show higher nutrient contents so that the nutrient export is higher and the balance becomes more negative.
