Fertilization Above and Below Ground Biomass and Species Number on Hog Island Dunes, 1991

A one-year study on the accreting north end of Hog Island, VA, provided the opportunity to quantify amounts of plant biomass along a natural dune chronosequence (24, 36, and 120+ year-old dunes) and biomass response to experimental additions of nitrogen. Total aboveground biomass, root biomass, and species number in 1-m2 plots on the dunes across the North Hog Chronosequence. Treatment plots included screened, fertilized, and screened & fertilized.
