ABSTRACT:
A method for determining the phytolithic organic carbon yield of a plant type at a location or region comprising: a) taking a sample of a plant type growing in the location or region; b) quantifying phytolithic organic carbon in the sample; c) quantifying a total biomass of the plant type growing at the location or region; and d) determining a total amount of phytolithic organic carbon for the total biomass of the plant type at the location or region.
