Long-term reduction in 137Cs concentration in food crops on coral atolls resulting from potassium treatment

Autor: Earl L. Stone, C.L. Conrado, Terry F. Hamilton, William L. Robison

Publikováno v: Journal of Environmental Radioactivity. 88:251-266

Bikini Island was contaminated on March 1, 1954 by the Bravo detonation (U.S. nuclear test series, Castle) at Bikini Atoll. About 90% of the estimated dose from nuclear fallout to potential island residents is from cesium-137 ((137)Cs) transferred fr

Fall-Applied Nitrogen Improves Performance of 1-0 Slash Pine Nursery Seedlings after Outplanting

Autor: Kris Irwin, Mary L. Duryea, Earl L. Stone

Publikováno v: Southern Journal of Applied Forestry. 22:111-116

This study examined the effects of supplemental nitrogen (N) applied to slash pine (Pinus elliottii var. elliottii [Engelm.]) seedlings in a north central Florida nursery. Treatments were applied during a 4 wk period during November and December, 198

Loss of nitrogen and bases after fertilization of second-growth hardwood forest soils

Autor: Earl L. Stone, John A. Stanturf

Publikováno v: Forest Ecology and Management. 65:265-277

Soils at five New York sites of a nitrogen fertilization study in second-growth mixed deciduous forests were sampled to determine the fate of applied N and possible adverse chemical changes from its application. Organic layer and mineral soil (0–10

Distribution and ratios of 137Cs and K in control and K-treated coconut trees at Bikini Island where nuclear test fallout occurred: effects and implications

Autor: Patrick O. Brown, Terry F. Hamilton, S. R. Kehl, Earl L. Stone, William L. Robison, C.L. Conrado

Publikováno v: Journal of environmental radioactivity. 100(1)

Coconut trees growing on atolls of the Bikini Islands are on the margin of K deficiency because the concentration of exchangeable K in coral soil is very low, ranging from only 20 to 80mgkg(-1). When provided with additional K, coconut trees absorb l

Boron deficiency and excess in forest trees: A review

Autor: Earl L. Stone

Publikováno v: Forest Ecology and Management. 37:49-75

Boron deficiency of forest trees occurs in many countries, notably in exotic plantations of eucalyptus and pines, but also in plantations and natural stands of native species on soils altered by macronutrient fertilization, fire or erosion. The sympt

The Longleaf Pine Islands of the Ocala National Forest, Florida: A Soil Study

Autor: Earl L. Stone, Paul J. Kalisz

Publikováno v: Ecology. 65:1743-1755

Longleaf pine-wiregrass-turkey oak (Pinus palustris-Aristida stricta-Quercus laevis) occurs as isolated islands, 60-4000 ha in area, in a matrix of sand pine-scrub (Pinus clausa-Quercus spp.) on deep sands of the Ocala National Forest, Florida. Strik

The variety of soil microsites created by tree falls

Autor: Earl L. Stone, Susan W. Beatty

Publikováno v: Canadian Journal of Forest Research. 16:539-548

The uprooting of forest trees leads to the formation of microsites on the forest floor, contributing to fine-scale heterogeneity in soil properties. We found the types of microsites formed depended on the way the tree fall occurred. Tree falls were c
