The AA. have investigated the potential of soil, which has been heated under reducing conditions to enhance its ferrimagnetic content, as a soil erosion tracer. For a suite of 16 magnetic concentration-dependent properties, values were found to be significantly greater, by at least one order of magnitude, after heating, both for the bulk soil and 9 individual particle size fractions. Individual size fractions could be differentiated using 2 different magnetic properties, thus illustrating the technique's potential to provide information on particle size-specific erosion. Soil box experiments demonstrated the potential for both in situ measurement of magnetic susceptibility and laboratory measurement of the magnetic properties of eroded sediment, to trace and quantify soil erosion.
