Abstract

The use of acid ammonium acetate (pH 4.65) as an extractant for plant available trace elements (Mg included) was studied on a total of 216 soil samples and of timothy samples from corresponding sites. Significant correlations between the results of soil and plant analyses were obtained for the eight elements studied in following soil groups: (1) Clay soils: Ni, Co, Cu (2) Coarse mineral soils: Ni, Co, Pb, Mg, Mo (3) Mineral soils (Groups 1 + 2): Ni, Co, Pb, Cu, Mo, Zn (4) Organogenic soils: Ni, Co, Pb, Mg, Mn (5) Whole material: Ni, Co, Pb, Cu, Mg, Mn, Mo, Zn.
