Abstract
Evaluating and possibly ameliorating the effects of base cation depletion in forest soils caused by acid deposition is an important topic in the northeastern United States We added 850 kg Ca ha−1 as wollastonite CaSiO3 to an 118ha watershed at the Hubbard Brook Experimental Forest HBEF a northern hardwood forest in New Hampshire USA in fall 1999 to replace calcium Ca leached from the ecosystem by acid deposition over the past 6 decades Soil microbial biomass carbon C and nitrogen N concentrations gross and potential net N mineralization and nitrification rates soil solution and stream chemistry soilatmosphere trace gas CO2 N2O CH4 fluxes and foliar N concentrations have been monitored in the treated watershed and in reference areas at the HBEF before and since the Ca addition We expected that rates of microbial C and N cycle processes would increase in response to the treatment By 2000 soil pH was increased by a full unit in the Oie soil horizon and by 2002 it was increased by nearly 05 units in the Oa soil horizon However there were declines in the N content of the microbial biomass potential net and gross N mineralization rates and soil inorganic N pools in the Oie horizon of the treated watershed Stream soil solution and foliar concentrations of N showed no response to treatment The lack of stimulation of N cycling by Ca addition suggests that microbes may not be stimulated by increased pH and Ca levels in the naturally acidic soils at the HBEF or that other factors for example phosphorus or Ca binding of labile organic matter may constrain the capacity of microbes to respond to increased pH in the treated watershed Possible fates for the approximately 10 kg N ha−1 decline in microbial and soil inorganic pools include components of the plant community that we did not measure for example seedlings understory shrubs increased fluxes of N2 and/or N storage in soil organic matter These results raise questions about the factors regulating microbial biomass and activity in northern hardwood forests that should be considered in the context of proposals to mitigate the depletion of nutrient cations in soilThis research was supported by grants from the National Science Foundation DEB 9726837 calcium addition study DEB 9810221 Hubbard Brook Long Term Ecological Research DEB0315211 Hubbard Brook Long Term Research in Environmental Biology and the Andrew W Mellon Foundation We thank Lisa Martel for help with field sampling and laboratory analysis and two anonymous reviewers for helpful comments on an earlier draft of the manuscript The views expressed in this manuscript do not necessary reflect those of the funding sources The Hubbard Brook Experimental Forest is operated by the Northeastern Research Station USDA Forest Service Newtown Square PA This paper is a contribution to the Hubbard Brook Ecosystem Study
