This dataset contains: 
Contents Description:
- quantitative data of P concentration determined by means of ICP-MS. 
  Concentrations are expressed in ppm which corresponds to ug P / mL dialysate solution for dialysate samples and to ug P / g soil for soil digests samples.
- modelling results

Files description:
- MD_SC_Pdatabase.xlsx
   This file contains quantitative P concentration data and SDs from ICP-MS analyses.
   The 5 sheets contain: replicates from microdialysis experiment (MD), replicates from suction cups (SC) experiment, MD averages, SC averages, total P concentrations in soil digests
- calibration_plots.opju
   This origin project contains the microdialysis and suction cups calibration data and plots
- CorC11.txt
   This file contains a list of average P concentration data in ppm from the first probe in the microdialysis experiment conducted with coarse soil.
- sol6.m
   This file contains a matlab function code that is used by the main matlab code to solve an ordinary differential equation for a given set of parameters to produce a distribution of P concentrations over time as predicted by the used mathematical model.
   Additionally, it also calculates an error of the calculated P concentrations with respect to the data from the microdialysis experiments.
- CorC12.txt
   This file contains a list of average P concentration data in ppm from the second probe in the microdialysis experiment conducted with coarse soil.
- CorC13.txt
   This file contains a list of average P concentration data in ppm from the third probe in the microdialysis experiment conducted with coarse soil.
- Depth.txt
   This file contains a list of depths in cm at which the P concentrations were obtained from the soil digests.
- ParamEst6.m
   This file contains a matlab code to obtain the diffusivity, adsorption and desorption rates of P in a soil column that provide an optimal fit of the P concentrations predicted by the mathematical model used, to the data from the microdialysis experiments.
- SDCorC11.txt
   This file contains a list of the standard deviations corresponding to the P concentration data from the first probe in the microdialysis experiment conducted with coarse soil.
- SDCorC12.txt
   This file contains a list of the standard deviations corresponding to the P concentration data from the second probe in the microdialysis experiment conducted with coarse soil.
- SDCorC13.txt
   This file contains a list of the standard deviations corresponding to the P concentration data from the third probe in the microdialysis experiment conducted with coarse soil.
- SoilData.txt
   This file contains a list of the average P concentration data in ppb, obtained from the soil digests.
