摘要：

Soil erosion may be difficult to quantify from redistribution of Cs-137 at sites where stubble-mulch techniques were adopted prior to Cs-137 deposition, because appreciable Cs-137 may have been transported before it was mixed into the soil Ap layer. We present evidence that this occurred in two long-term cropping experiments in southern Alberta.
