Interpretive Summary:

Technical Abstract: Plant availability of heavy metals from soil depends on factors such as soil type, organic matter, base saturation, texture, and salinity. Plant availability of mobile manganese (Mn) was accessed from various horizons of non-saline, medium saline, and highly saline sieriozem soils and a pasture. Manganese was extracted from soils using ammonium acetate or HCl and measured with colorimetry. Salt-soluble Mn concentration gradually increased with depth; acid-soluble Mn had more uniform concentrations throughout the profile. Both extractable Mn fractions differed little among the treatments. The lowest Mn concentrations were measured at 40 to 50 cm in the saline-free soils and at 60 to 70 cm in the saline soils probably as a result of leaching of the saline soils to remove salts.
