Seasonal changes in total fine-root biomass and the allocations of nitrogen and phosphorus to roots, root crowns, and leaves of Aristida stricta were measured on a North Carolina coastal plain savanna. Total fine-root biomass was determined from sequential root cores taken over 12 months. Total root biomass decreased from spring to late fall and then increased in winter. Root production and turnover estimates indicate that this low-fertility savanna has a relatively large root biomass and slow turnover. The pattern of allocation of biomass, nitrogen, and phosphorus to different tissues of Aristida stricta indicates that throughout the year the greatest percentage of biomass and nutrients is in roots.
