Abstract

In order to determine the nutrient demand of established cup plants plots, the mineral contents have been analyzed in the dried mixed samples and the resulting nutrient uptake was calculated. The Ca uptake of cup plant (22 kg per t DM) is classified as high in comparison to maize (ca. 2 kg per t DM). In addition large fluctuations were observed depending on the year of harvest. Whereas the Mg uptake was about twice as high as in silage maize, the nutrient uptakes for N and P were lower than for silage maize. With regard to K, a tendency of decreased nutrient uptake was observed with increasing age of the plants.
