Comparative characterization of humic acids from arable soils of the taiga, steppe, and semidesert zones

The parameters of the elemental composition, molecular weight distribution, infrared and proton spectroscopy, and hydrophilic-hydrophobic properties were determined for humic acids preparations isolated from arable horizons of soils from different natural zones (an ordinary chernozem, a soddy-podzol...

Description
Summary:	The parameters of the elemental composition, molecular weight distribution, infrared and proton spectroscopy, and hydrophilic-hydrophobic properties were determined for humic acids preparations isolated from arable horizons of soils from different natural zones (an ordinary chernozem, a soddy-podzolic soil, and a meadow sierozem). The general and specific properties of the humic acids from the three studied soils were revealed.
