“…For example, the exchanger phase was either washed repeatedly with small volumes of acidified NaCl (Barrow and Shaw, 1977;Bache and Ireland, 1980); or was boiled with small volumes of I M NazS04 (Brewster et al, 1975). Other approaches used include transfer of P-loaded resin into a small column before elution with IM NazS04 (Cooke and Hislop, 1963); and ashing the resin, followed by dissolution of the ash in HCI (Vaidyanathan and Talibadeen, 1970).…”

“…Other investigators have shown that the magnitude of the fraction transferred can be strongly influenced by the concentration of complementary salts in the aqueous phase. This parameter can vary with the volume of water present and the amount of exchanger used (Cooke and Hislop, 1963;Bache and Ireland, 1980). In one study (Brewster et al, 1975), the log of the water phase phosphate content (In Ps) was found to be linearly related to the total amount of P desorbed from the soil.…”

“…In soil studies, the recommended interaction times range from 16 hours (Cooke and Hislop, 1963) to 300 hours (Bache and Ireland, 1980), with the time required to achieve a pseudo equilibrium state tending to vary with experimental parameters. It has been noted, for example, that the rate of P desorption decreased on increasing the volume of water used (i.e.…”

“…A direct link between the amount of phosphate transferred to the exchanger resin and the amount ofP taken up by a crop grown on the soils has been found in some studies (Moser et al, 1959;Cooke and Hislop, 1963). Later investigations demonstrated that the analytical result can vary with the experimental parameters used, and this has led some authors (Barrow and Shaw, 1977;Bache and Ireland, 1980) to propose that there is no single value for resin extractable phosphorus.…”

Transfer of phosphate ions from sediment particles to an anion exchanger (Amberlite IR-48 or Duolit A378) has been used to determine the 'labile' (or 'available reactive') phosphorus content of several sah-water lake sediments. An evaluation of the procedure identified several sources of error, e.g. (i) incomplete transfer of P to the exchanger [due to competition for sites by other anions present in the dried sediments]; (ii) slow intermediate processes such as dissolution of inorganic phosphate compounds; (iii) sorbed P not fully retrieved from the exchanger resins [due to the limited efficiency (-90%) of the displacement process]; and (iv) absorbance readings in the colorimetric procedure used to determine phosphate can be enhanced by light scattered from fine particles. Accordingly, for the determination of the amount of 'labile' phosphate present in sediments it is recommended that one (a) stirs the exchanger/suspension system for at least 24 hours; (b) analyses both the aqueous phase and the resin phase; (c) extracts the resin phases at least twice with 1M NaCI; and (d) repeats the "transfer to resin" step after isolating the partly-washed sediment and re-suspending it in water. The contributions from steps (d) and the non-sorbed Pin the aqueous phase segment of (b) changed slightly with changes in the ratio of exchanger to sediment mass.

Bewertung verschiedener Parameter zur Feststellung des pflanzenverfügbaren Phosphats in alluvialen und kalkhaltigen Böden Ägyptens. Mit Hilfe von 32P wurde in Alluvial‐ und Kalkböden die Bewertung unterschiedlicher Parameter (Intensität, Kapazität und Kombination beider mit einem kinetischen Faktor) zur Kennzeichnung des pflanzenverfügbaren P vorgenommen. Zwischen dem P‐Gehalt in Weidelgras und der Intensität (P im 0,01 M CaCl2‐Extrakt, Verh. Boden/Lösungsmittel + 1/20, Schüttelzeit + 18 h) ergaben sich keine gesicherten Beziehungen. Die durch Isotopen‐Austausch und im Bicarbonat‐Extrakt gemessene Kapazität war dagegen sehr hoch korreliert mit der tatsächlichen P‐Aufnahme von Weidelgras in beiden Bodengruppen. Der E‐Wert (gemessen nach 14 d) ergab bei den Kapazitätsparametern die besten Beziehungen, gefolgt vom L‐Wert und dem E‐Wert nach 18 h, während die Bicarbonat‐Extraktion die schlechteste Korrelation lieferte. Am besten allerdings war die P‐Aufnahme durch die Pflanzen korreliert mit der P‐Menge, die durch Anionenaustauscher aus der Bodenlösung innerhalb von 16 h entfernt wurde. Dies stützt die Hypothese, wonach neben Intensität und Kapazität die Wiederauffüllungsrate von P in der Bodenlösung hinsichtlich seiner Pflanzenverfügbarkeit starke Bedeutung hat.

The availability of P for pasture plants in a range of acid hill soils with organic matter content up to 80 % was assessed by extraction, exchange, sorption, isotopic dilution and digestion methods and was verified by plant P uptake using ryegrass and white clover as test plants. Values obtained by the conventional extraction and equilibration methods were inversely but non-significantly related to P uptake expressed in mg kg-1 units: the relationships were only marginally improved with the data in mg litre-' units. The size of labile pool ('I,' value) and amounts of both total-and organic-P ranked the soils in the same order as P uptake, but only when the data were expressed in mg litre-1 units were the relationships highly significant. Reasons are suggested for the unsuitability of conventional extraction methods for acid, organic hill soils. Organic-P (in mg litre-' units) may provide the best indication of soil P status, but the determination of total-P appears to be the most practical alternative.
