Determination of structure features of soil profiles with various degree of cultivation on the basis of the main spectrophotometric coefficients and type of spectral reflection curves was realized in the conditions of the Republic of Belarus. As a result of realized research it was revealed that spectral curves of agro humus horizons of sod-podzolic light loamy soils and agro cultural horizons of agro soil slowly and fluently rose from short waves to the long waves; and, in dependence on humus content they had different location. Curves of sub-plough-layer also had their diagnostic signs: in agro sod-podzolic light- and moderately cultivated light loamy soils the curves of spectral reflection highly and quickly rose from short waves to long waves and specified at the presence of alluvial horizons; the spectral curve of sub-plough-layer of well cultivated light loamy soils settled down slightly lower, and in cultural agro soil looked like a curve which was typical for illuvial horizons. Curves of illuvial horizons of all investigated soils had accurately expressed excess (lifting) in the field of lengths of waves from 450 to 600 nanometers.
