Název v původním jazyce

The Rengen Grassland Experiment: plant species composition after 64 years of fertilizer application

Popis výsledku v původním jazyce

A long-term fertilizer experiment (the Rengen Grassland Experiment, RGE) was established in 1941 in the Eifel Mountains of Germany on low productive grassland naturally dominated by Calluna vulgaris and Nardus stricta. Six treatments combinations of Ca,N, P, and K fertilizer were applied annually: an unfertilized control, Ca, CaN, CaNP, CaNP-KCl, and CaNP-K2SO4. In mid June 2004, plant cover was visually estimated and sward height was measured aiming to detect changes in floristic composition caused bylong-term fertilization. Calculated by redundancy analysis (RDA), the effect of treatment was found to be a significant predictor of sward structure in the experimental area and explained 62 % of cover data variability. The largest difference in vegetation structure and composition was between the treatments without and with P application. Briza media was the dominant short grass in the control, Ca, and CaN treatments. Lathyrus linifolius was the dominant legume in the control and Carex
