Gjentatte jordprøver har nylig vist seg å være en effektiv måte å overvåke skogsjord endrer seg over år og tiår. For å støtte bruken av den, er en protokoll presenteres som syntetiserer den nyeste informasjonen om jord resampling metoder til hjelp i utforming og gjennomføring av vellykkede jord overvåkningsprogrammer.
