In a hops‐producing area long‐term average trapping‐effectiveness of a grassed filterstrip under agricultural use was measured. Copper, applied as fungicide, was used to identify the colluvium in a meadow below a hop garden. 9,5 t material were trapped during 17 years per m width of the filterstrip. This annual accumulation of 540 kg/m width represents a trapping efficiency of 55% of the computed annual soil loss of the hop garden. The results agree with other publications which report the trapping efficiency for a longer period, whereas the reported results of short‐term experiments largely overestimate the efficiency.
