Brief description
The dataset provides information on soil chemistry from a 10 year chronosequence sample of restoration in southern Australia. The parameters include: A) Physical properties- Soil moisture (%), Gravel (%) - ( >2.0 mm), Soil Texture, i.e.Course Sand (%) (200-2000 µm), Fine Sand (%) - (20-200 µm), Sand (%), Silt (%) (2-20 µm), Clay (%) (<2 µm), and B) Chemical properties- such as, Ammonium Nitrogen (mg/Kg), Nitrate Nitrogen (mg/Kg), Phosphorus Colwell (mg/Kg), Potassium Colwell (mg/Kg), Sulphur (mg/Kg), Organic Carbon (%), Conductivity (dS/m), pH (CaCl2), pH (H2O), DTPA Copper (mg/Kg), DTPA Iron (mg/Kg), DTPA Manganese (mg/Kg), DTPA Zinc (mg/Kg), Exc. Aluminium (meq/100g), Exc. Calcium (meq/100g), Exc. Magnesium (meq/100g), Exc. Potassium (meq/100g), Exc. Sodium (meq/100g) and Boron Hot CaCl2 (mg/Kg). This data would have application for land managers. The soil chemistry data is also related to the eDNA OTU table published on "https://doi.org/10.4227/05/5878480a91885", titled "Revegetation rewilds the soil bacterial microbiome of an old field. Part 1: OTU raw data matrix", and as such it would have an appeal to researchers undertaking a meta-analysis on eDNA and restoration outcomes.Lineage
Soil Collection: Three 25 m x 25 m quadrats were randomly selected per site, giving a total of 24 quadrats across the 8 sites. Soil was sampled from the 0-10 cm and 20-30 cm soil horizons at each quadrat. Nine soil samples were pooled into a sterile plastic bag, and homogenised using a sterilised trowel. 300 g soil was sampled from these pooled samples and outsourced or soil physical and chemical analysis.

This project forms a part of the lead author's PhD project. The information on soil chemistry data was generated for a manuscript published on the Molecular Ecology journal "Revegetation rewilds the soil bacterial microbiome of an old field" that uses eDNA assessment. It provides contextual soil chemistry data in support of the metabarcoding work.

text: The study system was an active restoration site at Mt Bold, a water catchment reserve of the Mt Lofty Ranges in South Australia (35.07;S, 138.42 E). This catchment was dominated by an open eucalypt woodland that has historically been subjected to tree clearance and grazing that began early in the 20th century. In this context, the native understory and most of the overstory was cleared and replaced by a grassland dominated by introduced grasses. At the study site, grazing ceased in 2003 when South Australia's water utility (SA Water) took over management. SA Water has actively restored the study site since 2005, with the restoration goal of recreating the local Eucalyptus leucoxylon dominated grassy woodland community.
