@article{bruck:prel-resu, author = "Dr. Robert Bruck Ph.D.", abstract = "This is a brief summary of our preliminary experimental data regarding the effects of Planters II on the growth and survival of red spruce and Fraser fir. As a brief introduction, I would state that red spruce and Fraser fir are the boreal montane ecosystem species here in the high Appalachians of the northeastern and southeastern US. These trees have undergone tremendous stress via air pollution over the past several decades and, indeed, certain airborne and satellite surveys have indicated that as much as 40 percent of this ecosystem has already died. There has been severe depletion of micronutrients as well as calcium and magnesium from the soil due to incessant insult from acid rain and cloud deposition. Many of the trees become yellow, followed by the abscission of needles and death. Two series of experiments have been conducted: first, under greenhouse conditions, and second, in the field. The data are summarized below.", journal = "Remineralize the Earth", number = "3", title = "{P}reliminary {R}esults for the {S}oil {R}emineralization {F}orestry {T}rials on {G}randfather {M}ountain in {N}orth {C}arolina ", year = "1992", }
