Methods of Soil Resampling to Monitor Changes in the Chemical Concentrations of Forest Soils

DOI: 10.3791/54815-v
What you'll learn
  • ✓ Design and implement a soil resampling protocol for long-term forest monitoring
  • ✓ Execute proper soil excavation, profile description, and sample collection techniques
  • ✓ Process and archive soil samples to detect chemical changes over decades
Protocol

Repeated soil sampling has recently been shown to be an effective way to monitor forest soil change over years and decades. To support its use, a protocol is presented that synthesizes the latest information on soil resampling methods to aid in the design and implementation of successful soil monitoring programs.

Difficulty
intermediate
Total time
~4–6 hours per sampling site (field work); processing adds 1–2 days per batch

Steps

1
Excavate soil profile and document characteristics

Excavate a representative soil pit and document the soil profile layers, including depth, color, texture, and structure. This establishes baseline conditions for accurate resampling comparisons.

2
Collect soil samples from designated depths

Systematically collect soil samples from specific horizons or depth intervals using standardized tools and techniques to ensure comparable samples across resampling events.

▶ 02:34
3
Process samples for chemical analysis

Prepare collected soil samples through drying, sieving, homogenization, and other processing steps required for accurate chemical analysis and long-term comparability.

▶ 04:09
4
Archive processed samples for future reference

Store soil samples under appropriate conditions with detailed metadata to enable quality control verification and allow reanalysis of archived materials over time.

▶ 05:53
5
Interpret chemical changes across forest soil types

Analyze results from long-term resampling studies showing detectable chemical changes in various forest and soil types over 8–27 year periods to validate monitoring effectiveness.
