Toward a common methodological framework

As isotopic analyses for the estimation of vegetation water use becomes more widespread, we need a common framework for the site description, sampling design, sample collection, transport and storage of samples, water extraction, in the laboratory or in situ, and analysis of the isotopic composition.

Our paper in brief

Soil and plant sampling

Soil and plant sampling

Here we describe the best practices for the sampling of plant and soil material to ensure preservation of the original water δ¹⁸O and δ²H, that is, practical guidance for minimizing sample evaporation and potential for fractionation.

Water extraction techniques

Water extraction techniques

Here we present the different extraction methods, their advantages and disadvantages, and the type of plant and soil material from which water can be retrieved.

Isotopic analyses

Isotopic analyses

Here we describe the measurement process and provide recommendations for standardization.
