Aims Many soil scientists think that soil phosphate exists as discrete compounds of iron, aluminium and calcium and, accordingly, use chemical fractionation schemes to identify these compounds. Methods We reacted a sample of goethite and a sample of aluminium oxide with a phosphate solution under co...
