      abstract     = {The spatial variability of soil properties is poorly
                      understood, despite its importance in designing appropriate
                      experimental sampling strategies. As preparation for a
                      farm-scale agro-ecosystem services monitoring project, the
                      'North Wyke Farm Platform', there was a need to assess the
                      spatial variability of key soil chemical and physical
                      properties.The field-scale spatial variability of soil
                      chemical (total N, total C, soil organic matter), soil
                      physical properties (bulk density and particle size
                      distribution) and stable isotope ratios (δ(13) C and δ(15)
                      N values) was studied using geostatistical approaches in an
                      intensively managed grassland.The scales over which stable
                      isotopes vary (ranges: 212-258 m) were larger than those of
                      the total nutrients, soil organic matter and bulk density
                      (ranges: 84-170 m). Two visually and statistically distinct
                      areas of Great Field (north and south) were identified in
                      terms of co-occurring high/low values of several soil
                      properties.The resulting patterns of spatial variability
                      suggest lower spatial variability of stable isotopes than
                      that of total nutrients, soil organic matter and bulk
                      density. Future sampling regimes should be conducted in a
                      grid with <85 m distance between sampling locations to
                      sufficiently capture the spatial variability of the measured
                      soil properties on the 'North Wyke Farm Platform'.
                      Consultation of the management histories of the sampled
                      field revealed that it had previously comprised two fields
                      with contrasting management histories, suggesting an effect
                      of management legacy (>5 years) on the patterns of spatial
                      variability.},
