- Statement
- Intact soil cores were collected in spring 2014 using a Van Walt percussion (Cobra TT) core. Soil cores were taken to a depth of 1 metre and divided into 15 centimetre (cm) depth increments. Soil phosphorous was measured in detail using 5 different extraction methods. Standard Olsen-P was measured and compared to four alternative methods i.e. mimicking plant available phosphorous. Ion analysis was carried out using TXRF (Total X-Ray Fluorescence Analysis) S2 PICOFOX (Bruker). For nitrate analysis the vanadate methodology of Miranda et al. (2001) was followed. For ammonium analysis, the salicylate-nitroprusside and hypochlorite methodology of Mulvaney (1996) was followed. Dissolved Organic Carbon (DOC) and Total Dissolved Nitrogen (TDN) analysis was carried out using a Thermalox 5001.3 (Analytical Sciences Limited) instrument. For all soil available cations (Ca, Na, K) soil was extracted with 0.5 Acetic acid and analysis was conducted on the extracted solution. For all soil available C and N measurements soil was extracted with 0.5 M K2SO4 and analysis was conducted on the extracted solution. Total Carbon and Nitrogen (C_tot and N_tot) were analysed using thermal oxidation measured by an Elementar Vario Cube Select. Soil water content (SWC), Bulk density (BD) and Loss-on-ignition (LOI) and LOI-C were measured using standard techniques. To measure pH and conductivity a 1:2.5 ratio of soil to deionised (DI) water was used, so to 5g of soil 12.5 ml of DI was added. Samples were then placed on a flat-bed shaker for 30 minutes, removed and allowed to settle before measuring pH and EC using standard lab probes (Hanna 309 pH probe, UK; Jenway 4520 EC probe, UK). Biological (root and fine root biomass) parameters were assessed in the topsoil 0-15 cm in 5 cm intervals on six sites. Samples were prepared by removing any above ground vegetation, soil and stones.Roots were then scanned using the WinRhizo programme to measure parameters such as total root lengths, diameters and branching. Samples were then dried at 80 degrees Celsius to remove water content to calculate total root biomass (dry weight) and fine root biomass (dry weight). All results were entered into Excel spreadsheets. Results from all the analyses were combined into one Excel spreadsheet. Data were then exported from this combined Excel spreadsheet as .csv files for ingestion into the EIDC.
