Re-sampling for Soil-caesium-137 to Assess Soil Losses after a 19-year Interval in a Hunter Valley Vineyard, New South Wales, Australia

Soils in a lower Hunter valley vineyard, New South Wales, Australia, were sampled and analysed for caesium-137, an indicator of soil erosion status, in 1984-1985 and 2004. From the time of the vineyard's first establishment in 1971 to 1985, estimated soil losses were 250 tonnes (equivalent to 64.2 t ha−1 yr−1). Re-sampling in 2004 showed that soil losses were 48 tonnes in the 19 years since 1985, equivalent to 9.7 t ha−1 yr−1. The decline in erosion rates may be explained by a change in land and soil management from intensive cultivation to one of no cultivation (sod culture) in 1998, and a lower annual rainfall and fewer rain-days per year in the period from 1986 to 2004
