Spectral reflectivity of certain soils in the chu river valley kazakh ssr ussr

The spectral reflectivity of various soils in the Chu River Valley was studied. Data were collected for meadow-bog, crustal-puffic meadow solonchak, desertifying meadow-bog, and takyr-like soils. Spectral reflectivity readings were taken by means of an SF-14 spectrophotometer over a range of 400-750 nm. Spectral reflectivity for the soils was at a minimum in the blue-violet part of the spectrum (15-25% at 400 nm) and at a maximum in the red part of the spectrum (27-48% at 750 nm). Graphs showing the change of spectral reflectivity as a function of depth under the surface and humus content are given for all 4 soil types.
