Slash Treatment After Clearcutting Lodgepole Pine Affects Nutrients in Soil Water
Abstract:Soil solutions from old-growth lodgepole pine (Pinus contorta Dougl. ex Loud.) stands in western Wyoming differed from solutions beneath adjacent clearcuts where four residue disposal methods were applied. Soil solutions from clearcuts were more concentrated in sodium, potassium, magnesium, calcium, and nitrate. All elements, especially, nitrates, were most concentrated under burned windrows of debris. Phenol concentrations under a mulch of wood chips were high during the first posttreatment year, and sometimes exceeded 1 milligram per liter. Dilution of potassium, nitrate, and phenol concentrations would be expected as water moves from the soil to streamflow.
