Forest plot soil moisture estimation using the cosmic-ray neutron (CRN) method and gamma-ray spectrometry (GRS)

Poster presented at the AGU 2021 conference.

  • In forests, the water input to the ground is highly variable resulting in an uneven soil water content.

  • Methods for estimating soil moisture at forest plot scale are necessary to understand the forest water budget.

  • Gamma-ray spectrometry (GRS) can be used to estimate soil moisture using the procedure presented by Baldoncini et al. (2018).

  • Soil moisture can be estimated for several depths using GRS measurements.
