CATION DEPLETION IN NEW ENGLAND FORESTS
1-Complex Systems Research Center, University
of New Hampshire, Durham, NH 03824. 2-USDA Forest Service, Northeastern
Forest Experiment Station, Durham, NH 03824.
Preliminary results are presented from a case study designed to
evaluate the potential for cation depletion in low-elevation forest
soils of northern New England and New York. Samples of foliage,
wood, and soils were collected in August, 1993 from plots with deep
sandy soils that had previously been cleared or harvested and are
now dominated by mature stands of either red oak or white pine.
Plots were located in New York, Vermont, New Hampshire, Maine, and
Massachusetts. Planned and/or completed analyses include extractable
and total nutrients for soils, total nutrients in foliage, and extractable
nutrients in wood. Nutrients include Ca, Mg, K, Fe, Mn, Al, N, and
P. Results presented here include nutrient values in green foliage
sampled from upper and middle layers of the canopy.
