Structure and Cation Content of a Podzolic Soil of Long Island, N. Y., Seven Years After Destruction of the Vegetation by Chronic Gamma Irradiation
1973
Horrill, A. D. | Woodwell, G. M.
Chronic gamma irradiation of an oak—pine forest in central Long Island, New York, has reduced the structure of the forest systematically and started changes in the structure and nutrient content of the soils. The most important changes have been reduction of the litter and humus horizons and a decline in loss—on—ignition in most horizons. Nutrient content of soils has clearly been augmented by minor disturbance of the vegetation and reduced by more severe disturbance. The soil content of phosphorus and calcium were exceptions, increasing along the gradient of radiation toward the highest exposures.
