2 LUCAS Soil

3 Sampling strategy First phase sample for stratification: orthophoto interpretation 2km squared grid points LAND COVER classes 1 ARABLE LAND 2 PERMANENT CROPS 3 GRASSLAND 4 WOODED AREAS AND SHRUBLAND 5 BARE LAND, RARE VEGET. 6 ARTIFICIAL LAND 7 WATER Second phase sample: in-situ data collection Parameters Land cover Land use pictures etc. Ground survey Sample of around 260,000 pts

4 Informative content Parameters: Land cover (1 & 2) Land use (1 & 2) Land Cover percentage Area size SOIL SAMPLE Height of trees Width of features Transect (250 m to east) with Land Cover and linear features Land management (grazing) Water management North West East South

5 Soil Harmonised data on soil parameters in Europe. Topsoil sample collected at 10% of control points = 20-25,000 samples. Stratified by land cover bias to agricultural land Composite sample from LUCAS point + cardinal points 2m distance 2009 = EU 25 (unofficially MT, CY & IS) 2012 = BG + RO 2015 = EU 28 (unofficially Western Balkans + CH x LUCAS protocol/augur) 2018 = EU 28 +? SOIL SAMPLE

6 Analysis 2009/2012 coarse fragments particle size distribution (% clay, silt and sand content) ph (in CaCl2 and H2O) organic carbon (g/kg) carbonate content (g/kg) phosphorous content (mg/kg) total nitrogen content (g/kg) extractable potassium content (mg/kg) cation exchange capacity (cmol(+)/kg) multispectral properties heavy metals (As, Cd, Co, Cr, Cu, Fe, Hg, Ni, Mg, Mn, P, Pb, V and Zn)

7 Analysis 2015 (new issues) coarse fragments (only for c new samples) particle size distribution (only for c new samples) ph (in CaCl2 and H2O) organic carbon (g/kg) carbonate content (g/kg) phosphorous content (mg/kg) total nitrogen content (g/kg) extractable potassium content (mg/kg) cation exchange capacity (cmol(+)/kg) electrical conductivity (ms/m) multispectral properties possibly (tender ongoing) Clay mineralogy 400 samples possibly (tender ongoing)

8 Analysis 2018 Core soil sampling Heavy metals targeted points (high values in 2009/ control sample) Bulk density (c. 8,000) points Soil organics (c. 1,000 points) Soil biodiversity by DNA extraction Pesticide residue / organic pollutants? Change 2009/2012 v 2015 Results end 2017

12 Discussion points How to adapt sampling to incorporate assessment of soil functions Visual soil analysis as proxy for soil function Analytical procedure as proxy for soil analysis Revise distribution of LUCAS Soil points by land cover categories Enhance biological aspects (reflect more ecosystem services)
