Sampling and Analysis of Soil

Survey code: SO

Monitoring System: Level II

Survey frequency: Every 10 years

Forms

  • PLS: Plot file

  • PRF: Soil profile description

  • PFH: Soil profile horizons

  • SOM: Soil analysis

  • LQA: Laboratory QA/QC information

Special Notes

During the FutMon project we will rely on the BioSoil definitions and recommendations.

Concerning the data submission the forms below will be used for data on plots which were not already submitted to the BioSoil data base.

Some amendments to BioSoil were made already and highlighted by blue bold font.


The information on the WRB soil classification name is not longer part of the PLS file.

The same file can be used on Level I and Level II.

Mainly based on BioSoil submission forms; amended parameter in blue bold font;

Mandatory/Optional also picked from BioSoil; final discussion and definition after submission of the BioSoil database to FutMon data centre and FSCC.


PRF

Following attributes are MANDATORY IF they EXIST

  • rock_depth: Rock depth of the soil profile (in cm from mineral soil surface)

  • obstacle_depth: Obstacle depth of the soil profile (in cm from mineral soil surface)


PFH

Following attributes are MANDATORY IF they EXIST

  • hor_discontinuity: Horizon discontinuity

  • hor_master: Horizon master

  • hor_subordinate: Horizon subordinate

  • hor_vertical: Horizon vertical


PFH

Following attributes are MANDATORY for MINERAL HORIZONS

  • structure

  • colour_moist: Moist colour of the soil matrix (Munsell soil colour charts)

  • colour_dry: Dry colour of the soil matrix (Munsell soil colour charts)
