  1. WP5 progress report on Soil Compaction pilot studiesby Catalin SIMOTANational Research & Development Institute for Soil Science, Agricultural Chemistry and EnvironmentBuharest - Romania

  2. Location and site description

  3. Location and site description

  4. Distribution of arable areas with the major forms of relief

  5. Distribution of grassland areas with the major forms of relief

  6. Soil Profiles  Soil Monitoring 16 x 16 km grid – WP2 PROFISOL – Romanian database for soil profilesHomogeneous soil-terrain-climate units (TEO)

  7. Coverage with soil profiles of the mapping units resulted from the intersection between soil (1:200,000) and Homogeneous soil-terrain-climate units (1:500,000) layers PROFISOL RO-MONITORING PROFISOL & RO-MONITORING

  8. Data availability for indicator calculation • Data sources • RO-Monitoring • PROFISOL – agrophysical soil database • Data quality • Bulk density data ISO 11272:1998 • Soil water content: Romanian standard compatible with ISO 11274:1998 pf: 1.4; 1.6; 2.0 Interpolation for pf=1.7 (5 kPa) • Sampling design and compatibility with WP2 recommendations • Monitoring : Sampling strategy : grid 20 x 20 m • PROFISOL : Soil profiles with 4 replicates for undisturbed samples

  9. Description of compilation of the data base Existing databases (PROFISOL & Monitoring) structured according with FAO-MicroLeis are in the process of conversion to SoDa

  10. Methodology used for calculations / estimations of parameters and indicators • Use off data from existing soil databases according with the procedures and protocols of WP4

  11. Definition of baselines • Bulk density as predicted by soil-mechanics based models considering soil compaction based on the weight of upper soil column to the considered depth • Definition and application of thresholds • Packing Density: 1.4 / 1.75 • Air Content: 5%, 10%

  12. CP01 Density

  13. Packing DensityMeasured data

  14. Packing DensitySoil under the compaction of the weight of overlying layers

  15. Packing DensityTopsoilBaseline & Measured

  16. Packing DensitySubsoilBaseline & Measured

  17. Validation of Soil structure-Packing density conversion tables

  18. Inherent susceptibility classes (Packing density + Texture)

  19. CP02 Air Capacity

  20. Testing the indirect method (Wösten) for calculation of soil water content at 5 kPa matric potential

  21. Testing the indirect method (HYPRES) for calculation of soil water content at 5 kPa matric potential

  22. Frequency distribution of soil air content (topsoil & subsoil)

  23. CP06 Vulnerability to compaction

  24. CP06 Vulnerability to compaction (ENVASSO Factsheets)Arable

  25. CP06 Vulnerability to compaction (Precompression stress)Arable

  26. CP06 Vulnerability to compaction (Soil stability defined as the ratio between precompression stress and soil pressure)Arable

  27. CP06 Vulnerability to compaction (ENVASSO Factsheets)Grassland

  28. Evaluation of the procedures and protocols • Feasibility and experience of applying the ENVASSO procedures and protocols • Conclusions and recommendations for revision of ENVASSO system
