Hubbard Brook Experimental Forest Watershed 1 Temporal Canopy Leaf Chemistry, 1999 - 2002

Overstory foliage is collected in late summer from calcium-treated forest on watershed 1.
Nutrient concentrations in foliage are measured. This allows us to estimate the pool of nutrients in
foliage in combination with litterfall estimates of foliage biomass. We can compare foliar chemistry
in W1 with that in W6 to quantify calcium treatment effects. Long-term measurements continue with the aim of detecting trends in foliage chemistry over long time scales.
