Zinc speciation in soil solutions of Vertisol locations
Aims

Evaluate the chemical forms of zinc in the soil solutions of Vertisols used for cereal cropping.

Key messages
  • Soil solutions were obtained by a centrifugation method from 14 unfertilised and fertilised Vertisols.
  • The soil solutions were analysed for all major cations and anions and organic carbon zinc in the soil solution exists mainly as free zinc2+ ions in these soils.
  • Complexation of total soluble zinc by organic and inorganic ligands constituted 40% and 5096, respectively, of total soluble zinc in fertilised and unfertilised soil solutions.
  • The organo-zinc complexes constituted.
