Resin-available nutrients in the O horizon in the MELNHE study at Hubbard Brook Experimental Forest, Bartlett Experimental Forest and Jeffers Brook, central NH USA, 2011-present

The MELNHE study looks at patterns of resource limitation through
nutrient manipulations in three study sites in New Hampshire: Bartlett
Experimental Forest, Hubbard Brook Experimental Forest, and Jeffers
Brook, located in the White Mountain National Forest. The
investigation is monitoring stem diameter, leaf area, sap flow, foliar
chemistry, leaf litter production and chemistry, foliar nutrient
resorption, root biomass and production, mycorrhizal associations,
soil respiration, heterotrophic respiration, N and P availability, N
mineralization, soil phosphatase activity, soil carbon and nitrogen,
nutrient uptake capacity of roots, and mineral weathering. This data
set includes phosphate, nitrate and ammonium availability measured
using resin exchange strips.

These data were gathered as part of the Hubbard Brook Ecosystem Study
(HBES). The HBES is a collaborative effort at the Hubbard Brook
Experimental Forest, which is operated and maintained by the USDA
Forest Service, Northern Research Station.
