EUROPEAN SOIL DATABASE
version 1.0
 1:1,000,000 Soil geographic database v. 3.2.8.
 European Soil Profile Analytical database.
 HYPRES pedo-transfer functions.
SOIL PROFILE ANALYTICAL
DATABASE - SPADE 1
 Soil horizon property data for ‘dominant’ STU’s.
Many STU’s have no data.
 Particle-size, O.C., pH Bulk D., Hydraulic
properties, CEC, Base saturation.
 ‘Measured’ data set - Some missing properties.
 ‘Estimated’ data set - All properties estimated,
but method indicated.
 Only one land use per STU - Often not arable.
SPADE2
PROJECT OBJECTIVES
 Expand the ‘Estimated’ soil profile database to
include ‘primary soil properties for ALL STU’s.
For the 15 EU countries only.
 Primary Soil Properties are:
clay%, silt%, fine sand%, medium sand%, coarse
sand%, organic carbon%, pH, Bulk density.
SPADE2
Project & Database administration
 Funded by ECPA.
 Co-ordinated by National Soil Resources Institute,
Cranfield University, UK
(Project manager. J.M. Hollis).
 Sub-contracts to National data providers from all 15
EU countries
SPADE2
Database administration
 Fourth component of the European Soil Database.
 Available under the same terms and conditions as
the existing database.
 All ECPA members will hold a ‘royalty free’ copy.

SPADE-2 – Project Overview
 All 15 National soil data providers contacted about participation.
 Negative response from Austria & no reply from Greece (even
after several contacts!).
 Project started November, 2002.
 Protocols for data generation and formal sub-contracts sent to
National data providers.
 Data providers from France, Spain, Sweden & Ireland did not
respond to sub-contracts.
 All other countries (Belgium & Luxembourg, Denmark, Finland,
Germany, Italy, Netherlands, Portugal, UK) completed data
supply by March 2004).

Data Derivation Protocol
If at least 5 measured data points are available for the land use-specific STU:
 Calculate the mean value and the standard deviation.
 Use expert judgement to assess whether these values are relevant for the land usespecific STU.
 If you consider the values to be representative, insert them into the ‘mean value’ and
‘standard deviation’ columns.
 If you consider them to be unrepresentative, use expert judgement to adjust the
calculated mean value to a more representative value and put ‘-8’ in the standard
deviation column.
If less than 5 measured data points are available for the land use-specific STU:
 Calculate the mean value.
 Use expert judgement to assess whether this value is relevant for the land use-specific
STU.
 If you consider the value to be representative, insert it into the ‘mean value’ column
and put ‘-1’ into the standard deviation column.
 If you consider the value to be unrepresentative, use expert judgement to adjust it to a
more representative value and put ‘-8’ in the standard deviation column.
If no measured data points are available for the land use-specific STU:
 Use expert judgement to assess a relevant mean value for the property and put ‘-9’ in
the standard deviation column.
