This dataset contains nutrient data from soils and microbial biomass in soils from an experiment based at Winklebury Hill, UK. The experiment used seeds and plug plants to create different plant communities on the bare chalk on Winklebury Hill and tested the resulting carbon and nutrient cycling rates and compared these to the characteristics of different plant functional groups. The experiment ran from 2013 to 2016 and this dataset contains data from 2014 only. This experiment was part of the Wessex BESS project, a six-year (2011-2017) project aimed at understanding how biodiversity underpins the ecosystem functions and services that landscapes provide.

Ammonium, nitrate and total nitrogen were measured using a Seal Analytical AA3 autoanalyser with UV digester, running 5% analytical replicates, recalibration (at 5, 4, 3, 2 and 1 ppm) and blanks every 20 samples. Carbon was measured using a Shimadzu TOC analyser, running 5% analytical replicates and blanks every 20 samples. Extracts were adjusted for soil moisture. Standardised protocols were followed in all cases, details of which can be found in the supporting documentation.
