Estimated means and variances of soil carbon and bulk density in topsoil by crop, land cover and soil type

Average and variance (standard deviations) of soil carbon concentration (g/kg) and bulk density (g/cm3) derived from Countryside Survey 2007 data, grouped by habitat type, crop type (for arable habitats) and split by soil type derived from the British Geological Survey Soil Parent Material 1km dataset. Soil carbon concentration was derived from loss on ignition determined by combustion of 10g dry soil at 375 degrees C for 16 hours multiplied by 0.55, bulk density was determined as the dry weight of soil (dried at 105 degrees C) per volume of soil.
