“…Zero tension lysimeters (e.g., Geary andDriscoll, 1996, Giesler et al, 1996) have also shown that the O horizon is a source of Si in drainage water, but these studies, too, did not recognize the likely contribution of phytoliths to this Si.…”

“…Excess N will export any exchangeable soil cations, but loss of calcium (Ca) is of particular concern be-cause trees require large amounts of Ca (Lawrence et al 1995). This has led to the suggestion that Ca addition may be an appropriate countermeasure to the effects N saturation (Geary and Driscoll 1996;Wargo et al 2002;Juice et al 2006).…”

We determined responses of red spruce ( Picea rubens Sarg.) – balsam fir ( Abies balsamea (L.) Mill.) forests to 6 years of nitrogen (N), calcium (Ca), and N + Ca treatments (100, 160, and 260 kg·ha–1·year–1 of N, Ca, and N + Ca, respectively) in New York (NY) and New Hampshire (NH). Forest responses to Ca treatments were also determined in Vermont (VT). Nitrogen treatments increased aboveground net primary production (ANPP) by 33% and 25% above controls in NY and NH, respectively. Similarly, N + Ca treatments increased ANPP by 27% and 28% in NY and NH, respectively. Calcium treatments increased ANPP by 25% and 21% above controls in NY and VT. Calcium treatment did not increase ANPP in NH, suggesting N, but not Ca limitation. Leaf-litter quantity and quality, and soil C and N storage were greater in treated than in control plots. Fine-root mass and production did not differ among treatments. Trees, therefore, assimilated more soil nutrients without increasing root growth in treated plots. Red spruce ANPP, however, declined or remained unchanged in response to N and Ca additions. The equivalent of 68–102 years of anthropogenic N addition to soils changed forest species composition without decreasing ANPP, and Ca additions did not prevent this change.

“…4a, c) are similar to the soil chemical changes induced by lime application. The application of lime to forest soils stimulates net nitrification and NO 3 -leaching from soils (Robertson 1982;Marschner et al 1992;De Boer et al 1993;Kreutzer 1995;Geary and Driscoll 1996;Simmons et al 1996;De Boer and Kowalchuk 2001;Nilsson et al 2001;Nohrstedt 2002). Likewise, the alkalinization in 1996/1997 at the study site (Fig.…”

Soil and stream water acidification in a forested catchment in central Japan

Rapid industrialization in East Asia is causing adverse effects due to atmospheric deposition in terrestrial and freshwater ecosystems. Decreasing stream pH and alkalinity and increasing NO 3 -concentrations were observed throughout the 1990s in the forested Lake Ijira catchment in central Japan. We investigated these changes using data on atmospheric deposition, soil chemistry, stream water chemistry, and forest growth. Average atmospheric depositions (wet ? dry) of 0.83, 0.57, and 1.37 kmol ha -1 year -1 for hydrogen, sulfur, and nitrogen, respectively, were among the highest levels in Japan. Atmospheric deposition generally decreased before 1994 and increased thereafter. The catchment was acidsensitive; stream alkalinity was low (134 lmol c l -1 ) and pH in surface mineral soils decreased from 4.5 in 1990 to 3.9 in 2003. Stream NO 3 -concentration nearly doubled (from 22 to 42 lmol c l -1 ) from the late 1980s to the early 2000s. Stream NO 3 -concentration was
