Abstract A device for sampling the root zones of marsh plants and a method for processing the resulting cores are described. Using these techniques, five stands of marsh plants were sampled and their macro‐organic matter profiles compared. The least total macro‐organic matter was found in the high vigor Spartina alterniflora Loisel. and the Distichlis spicata (L.) Greene root zones. Within S. alterniflora stands, the macro‐organic matter in the soil profile increased as vigor of the aerial portions decreased. Juncus roemerianus Scheele and short form S. alterniflora profiles were similar in shape and had the highest macroorganic matter content.
