HUMOUS CONTENT AND REFLECTIVITY OF UPPER HORIZONS OF SOILS OF THE SOUTHERN REGIONS OF EUROPEAN RUSSIA

摘要

Literature and authors' data served as basis for compiling a schematic map of humous content in upper soil horizons for the European Russia south; the 0.5 percent of humus has been chosen for the steps in the legend. A schematic map of reflectivity coefficients at 750 nm with 4 percent as legend's steps has been compiled for the same area.
