N2 - Eco-Cybernet combines various spatial-temporal information sources and numerical simulators with management decisions. The focus here is the development of a field-based monitoring tool capable of measuring soil origin for assimilation within Eco-Cybernet. The tool, referred to as fingerprinting, uses carbon and nitrogen isotopes and C/N as tracers that fraction in-stream eroded-soils into their land-use/land-management sources. Here, 245 soil data are presented for the tracers from agriculture and forest land-uses in the Upper Palouse, and differences within the bio-chemical cycles are discerned. Among the agriculture vs. forest land-uses, the nitrogen isotope is primarily dependent upon harvesting practice, the C/N is dependent upon litter inputs, and the carbon isotope shows little difference due to the monoculture C3 environment. The tracers are utilized within the fingerprinting tool, and a Bayesian unmixing model is used to measure source contribution to the eroded-soil. Uncertainty is accounted and attributed to a number of potential processes.
