Phosphorus uptake by Abadia variety wheat grown in soils of Ebro Valley

Year: 1983

Type: article

Abstract: Under greenhouse conditions the P uptake by wheat is studied and soil P extracted by three laboratory tests is compared. \nIn these soils the critical level of available P depends on the laboratory method used. Thus for the Burriel-Hernando extracting solution, it is 80 ppm while the method of Olsen gives a value of 60 ppm: the lowest concentration being obtained by the procedure of van der Paaw-Sissingh 40 ppm. \nThe regressions of plant yield on soil P extracted are studied to the critical level and equations are obtained which help to determine the amount to be applied to the soil. Differences are found in these relations for Brown Soil despite the same value of critical concentration.
