Pozdnyakov A.I., Eliseev P.I. DEPENDENCES OF SPECIFIC ELECTRICAL RESISTANCE FROM SOME PROPERTIES OF LOAMY SAND ARABLE SOILS IN CULTIVATED LANDSCAPES OF THE HUMID ZONEIt was ascertained, specific electrical resistance of loamy sand arable soils, measured both in a field, under natural high moisture, and in a laboratory, for samples moistens to a state of a paste, is strongly connected with such soil properties, as clay and humus content or cation exchange capacity. It's seemed to be very perspective to use the electrical resistance for the estimation of distribution topography of those properties inside the borders of a field during the development of precision agriculture and landscape-adopted farming or for different kinds of works.Key words: electrical resistance, degree of cultivation, loamy sand soils.
