Measurement of in situ Phosphorus Availability in Acidified Soils using Iron-Infused Resin

Popis výsledku v původním jazyce

A hybrid anion resin was tested for in situ phosphorus (P) availability measurement in soils of two stands recovering from acidification and having different P-sorption characteristics. The phosphate (P-PO4) sorption capacity of the resin (before saturation) was 48 mu mol g(-1). Sorption and elution were tested under P-PO4 concentrations common in acidic soils (0-0.42mmol l(-1)) either with or without the presence of sulfate (0.2mmol l(-1)). The efficiency of P-PO4 sorption was independent of the sulfate and was 100 +/- 0.2% (n=56, +/- SD). The P-PO4 recovery stabilized after six elution steps (each: 50ml of 0.5M sodium hydroxide, resin/solution 5:1). The efficiency of P-PO4 recovery was 80 +/- 7% and was used to evaluate field measurements. We determined the amount of P-PO4 in the field using resin bags in three consecutive years. The results indicate that bioavailable P is negatively related to the soil ability to retain P.
