Soil chemistry in forested Catskill headwater catchments

For each soil layer sampled, the following data are included in the data set: soil mass (except C horizons); coarse fragment volume (except C horizons); bulk density (except O, C horizons); layer thickness (except O, C horizons); loss-on-ignition (500 oC); pH in water and 0,01M CaCl2; exchangeable Ca, Mg, K, Na, Al and H; effective cation exchange capacity (CECe); exchangeable acidity; effective base saturation; CuCl2-extractable Al; total acidity; total CEC (CECt); organically bound Al and H, total C and N; C:N ratio; and total Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, P, Ni, Cr, Sc, V, Ba, Rb, Sr, Zr, Y, Nb, Ga, Cu, Zn, Pb, La, Ce, Th, Nd, and U. Stocks or pools of any element may be calculated by multiplying the concentrations by the corresponding soil masses.

本数据集包含各采样土层的如下数据：土壤质量（C层除外）、粗碎屑体积（C层除外）、容重（O层、C层除外）、土层厚度（O层、C层除外）、500℃灼烧减重、水浸提pH值与0.01mol/L氯化钙（CaCl2）浸提pH值、交换态钙、镁、钾、钠、铝及氢、有效阳离子交换量（effective cation exchange capacity, CECe）、交换性酸度、有效盐基饱和度、氯化铜（CuCl2）浸提态铝、总酸度、总阳离子交换量（total CEC, CECt）、有机结合态铝与氢、总碳与总氮、碳氮比，以及总硅、钛、铝、铁、锰、镁、钙、钠、钾、磷、镍、铬、钪、钒、钡、铷、锶、锆、钇、铌、镓、铜、锌、铅、镧、铈、钍、钕及铀。任一元素的储存库储量可通过将其浓度与对应土层的土壤质量相乘计算得到。
