Soil Themes > Soil Compaction > Maps - Data

The map of natural soil susceptibility to compaction was created from the evaluation of selected parameters from the ESDB. The soil susceptibility to compaction was divided into 4 categories. Two additional categories represent the data concerning places where this evaluation was either not relevant or could not been provided because of lack of information. In total there are 6 categories:

Data

(Nov 2009) For the purpose of research only, the data behind the map "natural soil susceptibility to compaction" are made available to the public. To get access to the data, fill in the online form. A report will accompany the data; note that this report is still in a draft stage and serves to explain the data of the map; it needs finalization.

Report

The Report on the Natural Soil Susceptibility to Compaction will be published soon

Map

Title: Natural susceptibility to compaction


Background Introduction: This map shows the natural susceptibility of agricultural soils to compaction if they were to be exposed to compaction. The evaluation of the soil’s natural susceptibility is based on the creation of logical connections between relevant parameters (pedotransfer rules). The input parameters for these pedotransfer rules are taken from the attributes of the European soil database, e.g. soil properties: type, texture and water regime, depth to textural change and the limitation of the soil for agricultural use. Besides the main parameters auxiliary parameters have been used as impermeable layer, depth of an obstacle to roots, water management system, dominant and secondary land use. It was assumed that every soil, as a porous medium, could be compacted.

Spatial coverage:27 Member States of the European Union where data available.

Conclusions

Susceptibility to compaction does not mean that a soil is compacted. It is the likelihood of compaction occurring if subjected to factors that are known to cause compaction. The actual status of the soils' compaction was not evaluated due to a lack of actual data concerning direct measurements.

Susceptibility to compaction depends on soil texture; it ranges from sandy (least susceptible) - loamy sandy - sand loamy - loamy -clay loamy - loam clayey - clayey soils - to clays (most susceptible to natural compaction)
