Annual primary productivity of Spartina alterniflora in control and fertilized plots at Law's Point, Rowley River, Plum Island Ecosystem LTER, MA.

Annual productivity is determined from aboveground biomass data in a Spartina alterniflora-dominated salt marsh plots on the Rowley River within the Plum Island Ecosystems (PIE) LTER site. Aboveground biomass is determined non-destructively.本数据集的年生产力基于普卢默岛生态系统（PIE）长期生态研究（LTER）站点罗利河区域内以互花米草（Spartina alterniflora）为优势种的盐沼样地的地上生物量数据测算得到。地上生物量采用非破坏性方法测定。
