Preliminary Data on the Magnetic Properties of Fallow Soils (Zelenodolsky District, Republic of Tatarstan)
Over the last few years, there has been an expansion of fallow lands in Russia due to issues in agricultural economics. Soils become fallow when left uncultivated for a time after successive crops. The recovery process depends on the duration of continuous arable farming in the area, soil type, area size and preferred land use methodology. Therefore, the importance of a comprehensive study of the processes occurring in fallow soils is reflected in their enormous expansion. In the course of soil formation, the transformation and migration of iron compounds change the magnetic susceptibility of soil. This suggests that magnetic susceptibility reflects the process of soil formation and may be considered a diagnostic indicator. This article presents the research results on the magnetic properties of fallow soils in Zelenodolsky district (Kazan). Samples of fallow sod-podzolic soils were used in this work. The magnetic properties of fallow soils were studied, and changes in the magnetic characteristics of fallow sod-podzolic soils were analyzed. The soil is characterized by the eluvial/illuvial type of profile patterns of magnetic susceptibility distribution. Evaluation of the contribution of the dia- /paramagnetic, superparamagnetic and ferromagnetic components from the coercive spectra shows that the increase in the magnetic susceptibility of sod-podzolic soils is due to the contribution of the ferromagnetic component.
