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


Location and site description

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


Data availability for indicator calculation

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


  • Description of compilation of the data base

    Description of compilation of the data base

    Existing databases (PROFISOL & Monitoring) structured according with FAO-MicroLeis are in the process of conversion to SoDa


    Location and site description

    Methodology used for calculations / estimations of parameters and indicators

    • Use off data from existing soil databases according with the procedures and protocols of WP4
