Description Soil organic matter (SOM) losses due to soil erosion may be considered low in continuous potato (Solanum tuberosum L.) cropping systems, but cumulated over time may cause considerable soil degradation. A field study was conducted in Kabete, Kenya, during the 2014 to 2015 rainy seasons to determine the effect of sediment particle size distribution on SOM losses and to assess the SOM fractions most susceptible to soil erosion under potato-legume intercropping systems. The treatments comprised of bare soil, pure potato stand (sole potato), potato + garden pea (Pisum sativa), potato + climbing bean (Phaseolus vulgaris), and potato + dolichos lablab (Lablab purpureus). A combined aggregate size and density fractionation was used to separate the sediment in size classes of aggregates 53 to 250 μm and in the sieve fraction
