Estimating soil loss from changes in soil cesium-137

A simple power-function equation was developed to relate changes in soil 137 Cs with time to an average annual soil-loss rate. The equation accounts for tillage dilution of the concentration of 137 Cs in the surface plow layer and for enrichment in the eroding soil. The predictions from the relation...

Description
Summary:A simple power-function equation was developed to relate changes in soil 137 Cs with time to an average annual soil-loss rate. The equation accounts for tillage dilution of the concentration of 137 Cs in the surface plow layer and for enrichment in the eroding soil. The predictions from the relationship were similar to values for a more complicated model and to measured values given in previous studies. Key words: Erosion rate, prediction, cesium-137
