Preliminary investigation on the use of 137Cs ( caesium- 137) to estimate erosion in Saskatchewan.

Abstract

Preliminary data indicate that noneroded soils in the Saskatoon area contain about 6.4 pC 137Cs/cm2. There was little variation in 137Cs with slope position on gently rolling sites under native vegetation, whereas there was considerable redistribution in cultivated fields. It was estimated that a knoll in one cultivated field had lost about 10% of its topsoil since the early 1960s when most 137Cs was deposited.-from Authors
