Description	Phosphorus (P) uptake and P contents in soils were measured in the topsoil and plant samples taken on six precise experimental field sites with different climatic conditions. Phosphorus concentrations were determined using water, 0.01M CaCl2, Mehlich 3 and anion exchange membranes (AEM) methods. All selected procedures showed that with increasing doses of applied P increased the mobile and readily available P contents. Correlation analyses were performed using the Spearman test. The closest relationship was obtained for P uptake by plants and the water extraction (r=0.81). Significant relationships were also obtained for plant uptake and the AEM, Mehlich 3 and CaCl2 methods (r=0.44, 0.40 and 0.36, respectively). Regression analysis was expressed best as linear regression. The closest relationship was found for water extracts and P uptake by plants (with a determination coefficient of 65%). Determination coefficients (R2) for P uptake and other methods used were significantly lower (max. 20%).
