Abstract

As preparation for a below ground food web study, the spatial variability of three soil properties (total N, total C and pH) and two stable isotopes (delta(13)C and delta(15)N of whole soil) were quantified using geostatistical approaches in upland pastures under contrasting management regimes (grazed, fertilised and ungrazed, unfertilised) in Scotland. This is the first such study of upland, north maritime grasslands. The resulting patterns of variability suggest that to obtain statistically independent samples in this system, a sampling distance of greater than or equal to 13.5 m is required. Additionally, temporal change (a decline of 1 parts per thousand) was observed in whole soil delta(15)N for the grazed, fertilised plot. This may have been caused by new inputs of symbiotically-fixed atmospheric N-2.
