Lucas user guide

Go to user guide main page The 2018 LUCAS campaign has been used to train Machine Learning algorithms.

Topsoil data for 18,984 samples from LUCAS 2018 are available as a CSV file and, to facilitate use of the data, an ESRI shapefile containing the theoretical points to which the taken samples should be associated; you may preview the readme file to find a description of these data.

Documentation: these data are accompanied by a  report  describing the 2018 dataset.

Geographical extent: European Union plus UK.

Format: CSV (with soil property data) + shapefile (theoretical sampling points, based on LUCAS Grid)

Measured properties: pH (CaCl2 and H2O), organic carbon content, CaCO3, nitrogen, phosphorous, potassium, EC (Electrical conductivity), Oxalate extractable Fe and Al .

Clay, silt, sand content and coarse fragments have been measured in previous surveys - these data will be made available in a single file in the very near future).

 
Reference Year: samples taken in 2018 .
 
Previous LUCAS campaigns topsoil data are found here  (2009/2012) and here (2015)

Note that for this dataset of basic soil properties, data of physical and chemical properties were analysed in samples taken at various depths in 18,984 LUCAS points as follows:

  • Samples taken from 0-20 cm depth in 18,744 points (in 141 of these points, all taken in Portugal, OC and CaCO3 were also analysed in additional samples taken from 20-30-cm depth)
  • Samples taken from 0-10 cm depth in 232 points,
  • Samples taken from 10-20 cm depth in 8 points

Further information from this LUCAS SOIL 2018 campaign is in preparation. These include:

  • As assessment of changes between 2009/2012 and 2018: report and summary data.
  • Heavy metals:  a summary of descriptive statistics of 997 LUCAS points with high and low concentrations of metals; the point data will not be made publicly available.
  • Erosion assessment: information recorded on gully erosion in 211 LUCAS points.
  • Assessment of depths of organic soils: measurements of organic horizon from 1,042 LUCAS points.
  • Biodiversity and plant protection products: report and summary statistics.
  • Environmental conditions: reference ancillary data describing a range of environmental conditions for all LUCAS points of the soil module; these data are the same as those distributed with the LUCAS SOIL 2015 data.

 

WALGREEN has downloaded tiff files for this dataset in order to offer them to users.

To query Lucas 2018 SOC datasets user must follow this steps, step 0 offers a link to the screen.
