This chapter updates methodological recommendations for belowground (root) production from previous reviews based on recent research in this rapidly developing field. A brief overview of the principles of belowground production measurement, and the strengths and limitations of a suite of methods is provided. Important considerations pertaining to choice of method and sampling strategy are described. Specific procedures, calculations and biases for coring, minirhizotron, elemental budgeting, and several isotopic methods are detailed. Finally, a case study comparing several commonly-used methods emphasizes the recommendation that multiple approaches are desirable in most belowground production measurement campaigns.

Keywords: roots; minirhizotron; isotope; coring; element budgets
