Method synopsis

Multi-temporal soil moisture measurements using TDR probe combined with soil coring and laboratory processing to determine moisture content, bulk density, and texture characteristics across environmental gradients.

Synthesized from method descriptions across 22 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Depth of nutrient uptake by deep-rooted plants is regulated by water availability (2026), PNAS. The protocol was originally introduced by Can fungal symbionts shift host niche dimensions to promote species coexistence? (2013). Implementations in other papers (listed below) may differ.

1. Install soil moisture and water potential sensors
   Soil moisture sensors and water potential meters were installed at 25 cm and 60 cm depths during a field trip. Measurements were recorded before, during, and after the water year 2025 to monitor shallow and deeper saturation.
   Quantities: Sensors at 2 depths (25 cm, 60 cm) at multiple locationsDuration: Monitored through water year 2025Conditions: Field installation during growing season
   Equipment: soil moisture sensors, water potential meters
