Evaluation of soil erosion rates in the southern half of the Russian Plain: methodology and initial results

The Russian Plain (RP) is divided into two principally different parts. The northern half of the RP is a predominantly forested area with a low proportion of arable fields. In contrast, the southern half of the RP has a very high proportion of arable land. During the last 30 years, this agricult...
