High percentage of growth reduction were obtained with calcium chelate, iron sulfate, ammonium oxalate, and EDTA disodium which have low pH values, but no complete reduction was observed for salts have a higher pH like sodium silicate.
There was little evidence of land use impact on plant-available P (Mehlich 1 P), HCl P as measured using ICP, and ammonium oxalate P, suggesting that these P fractions may not be useful indicators of P impacts.
2002) showed that only a fraction of water treatment residual total Al and Fe was extractable with ammonium oxalate (only 16 to 45 percent of total Fe and 45 to 80 percent of total Al was extractable with ammonium oxalate) which is important since ammonium oxalate extractable Al and Fe is considered an indicator of P sorption potential in water treatment residual (Dayton and Basta, 2005).
Iron and aluminium soluble in ammonium oxalate were determined by a method similar to that of Schwertmann (1964).
1991), now widely used in Western Australia; the pH of the soil measured in sodium fluoride as recently recommended by Gilkes and Hughes (1994); and the amount of Al and Fe extracted from the soil by ammonium oxalate (Schwertmann 1964).
For many soils from the south-west of Australia, P sorption capacity of topsoils is closely related to clay content, dithionite-citrate-bicarbonate (DCB) extractable Fe and Al, ammonium oxalate extractable Fe and Al, sodium pyrophosphate extractable Al, and pH(NaF).
