According to the authors, the final biomass removal quantity at clearing includes all above-ground biomass and a significant proportion of below-ground biomass. California almond production practices tend to result in shallow-rooted trees, and although some root material is left behind, the bulk of the below-ground biomass is removed.

The crop yield of 2.31 t/ha refers to kernel and is the weighted average of irrigated and non-irrigated plantations from year 7 till the end of the plantation life (year 25).
