Studying of soils granulometric structure at Pooskolye according to space pictures decoding

Work is devoted a problematics of deciding the soils granulometric structure according to Earth distance sound-ing of the Earth. On pictures of Landsat 5ТМ it was studied the soils granulometric structure at key area located on the left coast of Oskol river, in Old Oskolsky region in Belgorod oblast. Decoding results are compared with soil card and data of the granulometric structure laboratory analysis. Dependence between the maintenance of particles in the size less than 0,01 mm and reflective ability of soils in range of wave lengths of 630-690 na-nometers is revealed.
