Dynamics of carbon pools in post-agrogenic sandy soils of southern taiga of Russia
Abstract Background Until recently, a lot of arable lands were abandoned in many countries of the world and, especially, in Russia, where about half a million square kilometers of arable lands were abandoned in 1961-2007. The soils at these fallows undergo a process of natural restoration (or self-r...
