Identification and characterization of phosphorus-rich sandy soils

, : Identification and characterization of phosphorus-rich sandy soils. NJAS Wageningen Journal of Life Sciences 49(4): 369-384

For the identification of phosphorus-rich and phosphorus-leaky soils, various extraction methods have been proposed as indicators to estimate the risk of phosphorus (P) losses. In this study we compare and discuss the extractability of P from sandy soils, using various modifications of mild extractants (water and CaCl2), FeO-impregnated filter-paper strips (Pi-test), and ammonium oxalate (P-ox).
