. "Soil phosphorus fractions after seven decades of fertilizer application in the Rengen Grassland Experiment" . "Declining global P reserves require a better understanding of P cycling in soil and related plant uptake. On managed grasslands, application of lime and fertilizer affects not only soil nutrient status, but also plant-species composition of the sward. We examined the P fractionation in the Rengen Grassland Experiment (RGE) on a naturally acid Stagnic Cambisol in the Eifel Mts. (Germany) 69 y after the setup of the experiment. A modified sequential Hedley fractionation was carried out for samples from 30 plots at 0\u201310cm depth. Application of inorganic phosphorus fertilizer had diverse effects on inorganic (Pi) and organic P (Po) fractions. Resin-Pi, NaHCO3-Pi, NaHCO3-Po, NaOH-Pi, HCldil-Pi, HClconc-Pi, and HClconc-Po contents increased, while NaOH-Po significantly decreased and residual-P remained unaffected. Strongest enrichment occurred in the HCldil-Pi fraction, probably due to the chemical nature of the basic Thomas slag applied as P fertilizer. Without P fertilization, all fractions exc" . . .
