Abstract

This study was focused on a biological and a methodological question on root production and turnover. During the growth season, from May to September, ingrowth cores and soil cores were harvested for root production. Ingrowth cores on a high and low salt-marsh site were compared for root production. The high site had a significant (p<O.OO1) higher production of roots, but a significant (p<O.O5) lower rhizome production. Soil cores and ingrowth cores on the high site were compared, because both methods have some disadvantages. No consistency was found in previous studies in production using both methods. Before the first harvest, stable isotopes, 13C and '5N, were added in mid May, to calculate an independent value for root production and turnover. The roots from the harvested cores were divided by colour, for better tracing of the isotope during the growth season.
