Hydrologic and Water-Quality Conditions During Restoration of the Wood River Wetland, Upper Klamath River Basin, Oregon, 2003–05

Table 12. Losses of carbon, nitrogen, and phosphorus from soil cores, and comparison to Redfield ratio factors, Wood River Wetland, upper Klamath River basin, Oregon.

[Data from Snyder and Morace (1997) and D.T. Snyder (U.S. Geological Survey, unpub. data, 1997). Shading indicates cores closest to the ground-water piezometer nests. Redfield ratio factor: The loss ratio divided by the Redfield ratio (by weight); that is, a ratio of 1 would indicate balanced loss, whereas ratios greater than 1 indicate greater relative loss. Abbreviations: C, carbon; N, nitrogen; P, phosphorus]
