The use of a bottle sampler and a soil pipette to quickly and accurately sample soil‐water mixtures of known sediment concentrations was tested. Both devices failed to sample adequately soil‐water mixtures containing 1–187 gl −1 of solid particles. Poor sampling ability was attributed to rapid settlement of larger particles and to innate deficiencies in the sediment trapping ability of the samplers. These sampling devices should not be used to estimate sediment loads in runoff from soil‐loss plots, and erosion data from plot studies which have used a sediment sampling procedure should be treated with caution.
