Systematic-random sampling
1 soil profile
15 observations with soil auger
Monitoring protocol – soil inventory
Excavation, description and sampling by genetic horizons of the soil profile;
identification of topsoil and subsoil
What: laboratory determinations for soil profile horizons
(mandatory)
How: soil horizons characterization (pH, SOC, total N,
total carbonates, CEC, exchangeable Ca, Mg, Na and K,
base saturation, available P, particle-size distribution)
When: only at the beginning of the monitoring process
Monitoring protocol – soil inventory
What: topsoil and subsoil sampling (mandatory)
How: sampling with soil auger and obtaining composite
samples (not less than 10 subsamples in a plot – 1600
m2) from topsoil and subsoil (as defined accordingly to
the profile description)
When: at the beginning of the monitoring process and
every 10 years
