Summary Trace element levels extractable by 2-ketogluconic acid (2-KG), ammonium acetate, acetic acid, EDTA, and DTPA were determined in three different soils of the Tarves association. The 2-ketogluconic acid was derived from 2-litre batch cultures of a soil bacterium,Erwinia sp. Pasture grasses and clovers growing on these soils were also analysed. At the same pH, 2-KG extracted more Co, Ni and Zn and considerably more Fe, Ti and V than ammonium acetate. The quantities of Cu, Mn, Mo, Ni and Zn extracted by 2-KG from the three soils generally reflected, in a similar way to the other extractants, the contents of these elements in grasses and clovers growing on the soils.
