Abstract: This work has examined cobalt(II) binding by a variety of solid humic acids (HAs) isolated from peat, plant and soil sources at temperatures down to 60 K. The results confirm that X-ray absorption near-edge spectroscopy (XANES) measurements cannot distinguish between aquo and carboxylato ligands in

Abstract: Twenty seven Bradyrhizobium isolates were collected from fresh young nodules developed on soybean seedlings from six different locations in Egypt. After isolation, two types of colony morphology were observed: a “wet” type with flatter and entire edge associated with gum production, and“dry”
