This dataset includes soil mass, organic phosphorus, carbon and nitrogen concentrations for light and heavy fractions, obtained from soils collected from UK habitats. The dataset includes 20 soils, collected from the Ribble, Avon and Conwy catchments in the North West, South and North Wales respectively. Samples were split into light and heavy fractions using a physicochemical fractionation method. The dataset also includes recoveries of carbon, nitrogen and phosphorus as a measure of the efficacy of the fractionation method. Extra data on sampling location, catchments conditions and bulk soil texture are also included in this dataset.
Soil samples had been collected in a survey of the catchments of the Rivers Avon (Hampshire), Conwy (N Wales), Dee (NE Scotland), and Ribble (NW England) carried out between 2013 and 2015 (Toberman et al. 2016). Samples had been bulked from 6 or 10 separate cores, and included both topsoils and subsoils. We chose 20 soils to provide a range of SOM contents, and with sufficient light material to analyse. Most soils were under semi natural vegetation, three were from improved grassland. Arable soils were not analysed owing to their low contents of light material. We applied a modified physicochemical density fractionation method based on previously published procedures.
