Language: English Descriptors: Picea rubens; Seedlings; Acid rain; Mists; Acidity; Simulation; Seedling growth; Respiration; Photosynthesis; Nutrient content; Calcium; Magnesium; Rooting depth; Altitude Abstract: Two-year-old red spruce (Picea rubens Sarg.) seedlings were grown in a poorly buffered soil from a high-elevation site in the Great Smoky Mountains and exposed for 16 weeks to acid mist and rain chemically similar to that occurring at high- elevation sites in the southern Appalachian Mountains. Measurements of seedling growth, root distribution, saturated net photosynthesis, dark respiration, and nutrient content were made to test the hypothesis that acid deposition had caused reductions in the carbon economy noted at high-elevation sites in previous field studies. The role of base cation depletion in these changes was examined by evaluating soil amendments of Ca, Mg, or Ca plus Mg. Acidified rain and mist reduced (i) the apparent carbon economy of foliage, (ii) seedling growth, and (iii) rooting depth in these controlled greenhouse studies. Changes in gas exchange physiology paralleled responses observed for sapling trees in the field with increasing elevation and included both reduced net photosynthesis and increased dark respiration. Calcium deficiency induced by acid deposition is apparently an important mechanism underlying physiological responses of red spruce previously observed in the field. Calcium addition to soil partially reduced the effects of acid deposition, but observed responses suggest that both foliar- and soil-driven reactions are involved. Changes in carbon metabolism associated with reduced Ca availability, when high levels of acid deposition are superimposed on poorly buffered soils, support the inferential association of acid deposition with growth decline of mature red spruce in high- elevation forests of the Appalachian Mountains. 4 NAL Call.

Language: English Descriptors: Nevada; Cabt; Pinus monophylla; Cercocarpus ledifolius; Transpiration; Xylem; Growth; Water use efficiency; Seasonal variation; Geographical distribution; Spread; Diurnal variation Abstract: Red spruce seedlings growing in open top chambers in a nutrient-poor medium were exposed to mists containing one of five different combinations of H+, SO4(2-), NO3(-) and NH4+ ions, three at pH 5.6 and two at pH 2.5. The mists were applied twice weekly from May until November, and the plants overwintered outdoors with no additional mist treatment. Seedlings that received mists containing sulphate (1.6 mol m(-3)) the previous growing season were more frost-hardy (i.e., their dehardening was delayed) the following April than seedlings that received lower concentrations of sulphate or none. Neither ammonium nor nitrate in the applied mist had any effect on dehardening, but they did advance budburst when applied together. In the presence of sulphate there was no effect of ammonium-N on the time of budburst. Exposure to mists containing nitrogen significantly increased the dry weight and length of the leading shoots that emerged from the buds and extended the following summer. There was no evidence that the stimulatory effects of nitrogen on growth made the seedlings less frost-hardy in spring. 8 NAL Call. No.: S592.7.A1S6 Acid phosphomonoesterase activity of ectomycorrhizal roots in Norway spruce pure stands exposed to pollution. Rejsek, K. Exeter : Pergamon Press; 1991. Soil biology and biochemistry v. 23 (7): p. 667-671; 1991. Includes references. Language: English Descriptors: Czechoslovakia; Picea abies; Roots; Ectomycorrhizas; Acid deposition; Air pollution; Phosphorus; Bioavailability; Acid phosphatase; Enzyme activity; Biological indicators; Decline; Coniferous forests; Forest soils; Seasonal fluctuations; Temperate zones Abstract: The release of orthophosphate ions from organic compounds is essential for continuous phosphorus cycling in forest ecosystem. An important stage of this process in coniferous forests of the temperate zone is the production of acid phosphomonoesterase (PME) by ectomycorrhizal fungi. The effect of artificial and natural pollutant inputs during repeated short periods of high concentration on the activity of the specific enzyme was studied. The acid PME activity of spruce mycorrhizas was used as an indicator of anthropogenic pressure on forest soils. The seasonal dynamics of the activity of acid PME was monitored from February 1989 to January 1990. The results have showed a significant decrease of acid PME activity in ectomycorrhizal spruce roots as affected by pollutant input. The amount of acid PME activity may become one of the characteristic of the changing biochemical processes in soils under the effects of air pollution. The method presented is simple enough to be included in an integrated system of ecological analysis routinely used in field research to monitor forest decline. 9 NAL Call.

Language: English Descriptors: California; Pinus monticola; Salix; Fagaceae; Throughfall; Plant extracts; Leaves; Pine needles; Acid base equilibrium; Anions; Cations; Organic acids; Ion exchange; Mineral content; Rain; Acidity Abstract: Elemental composition data were obtained for bulk precipitation and throughfall samples and for aqueous extracts of the leaves of three woody plant species common in the subalpine Sierra Nevada range, California: chinquapin (Chrysolepis sempervirens Hjelmqvist), western white pine (Pinus monticola Dougl.), and willow (Salix orestera Schneider). The acid-base equilibria of the extracts were characterized by potentiometric titration and proton formation functions were computed. The latter then were modeled assuming four classes of quasiparticle acidic functional groups, yielding negative logarithms of conditional protonation constants in the range 4.8 to 5.0, 6.1 to 6.6, 7.4 to 7.7, and 9.1 to 9.4. The relative concentration of a given acidic functional group class varied markedly among the three woody species, but the conditional protonation constants were very similar. The model parameters, along with dissolved organic C concentration and pH values, were used to estimate net anion deficits in throughfall samples collected from the same sites as the leaf samples. On average, the calculated charge concentration of free organic anions in the western white pine extract matched the throughfall anion deficit, whereas the deficits in the chinquapin and willow throughfall samples were not accounted for by free anion concentrations. Metal complexation and in situ, species-dependent leaf surface processes may account for these latter differences. In general, the anion deficit and, therefore, organic acids were an important component of rainfall and throughfall charge balance. 25 NAL Call.

Language: English Descriptors: Phaseolus lunatus; Air pollution; Acid rain; Acid deposition; Fog; Ph; Crop damage; Abiotic injuries; Photosynthesis; Gas exchange; Net assimilation rate; Carbon dioxide; Stomatal resistance; Plant tissues; Susceptibility; Variation Abstract: Acute effects of high-nitrate/low-sulfate acidic fogs with a pH of 2.5 and 3.0 were investigated on 3.5- to 4-week-old Phaseolus lunatus L. in a series of replicated trials. After 24 hours, CO2 assimilation rates of primary leaves were reduced by at least one-third by 3-hour fogs with a pH value of 2.5 as compared to control plants treated with a fog of pH 6.3. A 3-hour fog at pH 3.0 reduced CO2 assimilation a minimum of 20%. Stomatal resistance increased in primary leaves of plants exposed to an acidic fog of pH 2.5 by >37% compared to plants subjected to pH 6.3 fogs. Stomatal resistances in leaves exposed to pH 3.0 fogs increased at least 27%. However, internal CO2 concentrations were not significantly different between control- and acid-fogged plants at any pH. Standardizing plants for similar CO2 assimilation rates allowed statistical separation of photosynthetically important variables as compared to unstandardized experimental designs with higher interplant variability. Methacrylate plastic sections of foliar lesions resulting from exposure to pH 2.0 fogs revealed that damage usually progressed vertically from the upper to lower epidermis. Xylem was less susceptible to damage than other tissues. 47 NAL Call. No.: HC79.E5E5 Agenda setting and acid precipitation in the United States. Alm, L.R.; Davis, C.

We monitored ambient soil solutions in undisturbed and experimentally manipulated soils from a fir [Abies balsamea (L.) Mill.]-spruce forest on Whiteface Mountain, NY, in order to characterize soil solution Al concentrations over a range of acid anion loadings. Under both natural and experimental conditions total Al and labile Al concentrations rarely exceeded values (180-250 micromole L-1) associated with reduced root growth in red spruce (Picea rubens Sarg.). Over a 2-yr period ambient soil solutions averaged 76 and 46 micromole L-1 total Al in the organic and mineral horizons, respectively. The highest monthly mean concentrations occurred in winter. Disturbance-induced NO3 accumulation and simulated acid rain applications produced higher peak Al values in experimental plots than were observed in undisturbed and untreated plots. Although soils of the fir-spruce zone exhibited the potential to yield solutions with phytotoxic Al concentrations, it appears that such concentrations are both spatially and temporally limited and infrequently present a direct stress to root growth in red spruce. 57 NAL Call.

Language: English Descriptors: West Virginia; Cabt; Acid deposition; Watersheds; Forests; Streams; Acidification; Nitrogen; Sulfur; Calcium sulfate; Nitrate nitrogen; Ph; Electrical conductivity; Water pollution Abstract: A whole-watershed manipulation project was begun on the Fernow Experimental Forest in West Virginia, USA, in 1987, with the objective of increasing understanding of the effects of acidic deposition on forest ecosystems. Two treatment watersheds (WS9 and WS3) and one control watershed (WS4) were included. Treatments were twice-ambient N and S deposition, applied via NH4SO4 fertilizer, with three applications per year. Three years of pretreatment data were collected and used for calibration. Stream water chemistry data collected during 3 years of treatment were evaluated. Stream water pH and electrical conductivity were not significantly affected by the elevated N and S inputs on either treatment watershed. On WS9, there were no statistically significant treatment effects on stream water export of Ca, SO4, or NO3 On WS3, however, stream export of both NO3 and Ca have increased as a result of acidification treatments. The implications of these results are discussed. Research is continuing so that the processes involved may be elucidated. In addition, effects on vegetation, aquatic invertebrates and amphibians also are being evaluated. 67 NAL Call.

Tree physiology v. 13 (2): p. 145-155; 1993 Sep. Includes references. Language: English Descriptors: Picea rubens; Winter kill; Cold resistance; Forest damage Abstract: Red spruce (Picea rubens Sarg.) seedlings growing outside in open-top chambers were sprayed twice weekly with artificial mists at either pH 2.5 or 5.6, for five months during the 1988 growing season. The mists contained one of the following: (water, pH 5.6 (control); (NH4)2SO4, pH 5.6; NH4NO3, pH 5.6; HNO3, pH 2.5; H2SO4, pH 2.5; or (NH4)2SO4 + NH4NO3, pH 2.5. During January 1989, the light responses of assimilation and stomatal conductance were assessed in the laboratory following a 4-day equilibration at 12 degrees C. The aerial portions of the intact trees were then subjected to a mild (-10 degrees C) frost for three hours during the night and the rate of recovery of light-saturated assimilation (Amax) was determined the following day using the same branches as were used for the assimilation studies before the frost treatment. The same trees were then subjected to a second frost of -18 degrees C for three hours during the following night and the recovery of Amax of the same branches was measured the next day. All of the acid mist treatments increased Amax and apparent quantum yield relative to the control treatment when measured before the frost treatments. Frosts of -10 and -18 degrees C resulted in a significant decline in Amax of seedlings in all treatments except the control. Stomatal conductance increased with increasing irradiance in seedlings in the acid mist treatments that did not contain SO4(2- ) ion. Stomatal conductance of seedlings in acid mist treatments containing SO4(2-) ion was insensitive to changes in irradiance over the range 50-1500 micromoles m-2 s-1. It is concluded that acid precipitation increased the sensitivity of the assimilation response to midwinter frosts that follow a brief warm period. The SO4(2-) ion appears to be significant in causing increased sensitivity to frost and in causing stomatal insensitivity to light flux density. 71 NAL Call.

Madison, Wis. : American Society of Agronomy; 1992 Jan. Journal of environmental quality v. 22 (1): p. 70-80; 1992 Jan. Includes references. Language: English Descriptors: Pinus taeda; Seedlings; Experimental equipment; Research; Air pollution; Ozone; Nitric acid; Air pollutants; Nitrogen; Deposition; Plant physiology; Nutrient requirements; Growth; Phytotoxicity Abstract: Many studies that address the impact of tropospheric O3 on agricultural and forested ecosystems utilize the open-top chamber. During the production of O3 using electrical discharge generators fed with dry air, there is an inadvertent addition of HNO3 vapor, a highly reactive trace gas. While several studies have proposed that HNO3 vapor introduces artifacts, none has measured concentrations of the odd-N2 trace gas in the chamber or investigated the fate of the N in the context of whole-plant physiology and growth. These questions were investigated using open-top chambers containing seedlings of loblolly pine (Pinus taeda L.) during the 1988 growing season in Oak Ridge, TN. The O2 treatments consisted of charcoal-filtered or subambient (0.96 micromoles m-3, 24-h mean), ambient (1.62 micromoles m-3, 24-h mean), and elevated (2.36 micromoles m-3, 24-h mean) concentrations, the last being accomplished by proportional O3 addition over the diurnal period. Measurements of the HNO3 vapor concentration during dry periods only (no rainfall or ground- level fog) averaged 28.6 nmol m-3 (subambient), 55.4 nmol m-3 (ambient air), and 240.0 nmol m-3 (elevated O3), an 8.4-fold range. For every 100 mol of O3 added to the chamber, 28 mol of HNO3 vapor were inadvertently added; this ratio is several times higher than that previously reported. This result, taken with published estimates of leaf conductance to HNO3 vapor, indicates a maximum N deposition in the form of HNO3 vapor ranging from 19.5 pmol N cm-2 leaf area h-1 (subambient O3) to 171.9 pmol N cm-2 h-1 (elevated O3). Given the nutrient content of the seedlings and knowledge of the fate of HNO3 vapor on the leaf surface and leaf interior, the degree to which N deposition via HNO3 vapor met the N requirements of the loblolly pine seedlings was estimated. Seedlings in the elevated treatment had an upper- limit estimate of 3.5% for the needles and 1.8% for the whole plant of N derived from HNO3 vapor. The concentration of HNO3 va 72 NAL Call.

Net throughfall fluxes (throughfall minus precipitation transfers) showed consistent canopy effects on rainfall chemistry, with SO4(2-), PO4(3-), Cl(-), K(+), Ca(2+) and Mg(2+) added to rainfall by foliage, whereas NO3(-)-N, NH4(+)-N and H(+) ions were absorbed from precipitation. Storm characteristics (event amount and duration) accounted for the largest portion of the variability in growing season net throughfall fluxes, suggesting that canopy exchange was the major mechanism of throughfall transfer. Stemflow fluxes increased canopy exchange rates of SO4(2-), PO4(3-), Cl(-), K(+), and Mg(2+) by greater than 20% in a regression model of total below- canopy element fluxes. Cation leaching fluxes were highly variable (C.V. > 50%) over spatial scales of several m2, but could be explained largely by heterogeneity in canopy cover. Foliar cation leaching losses in the early successional forest accounted for 4-13% of leaf nutrient reserves. As cation throughfall transfers were highest during storms with the greatest hydrogen ion uptake from rainwater, it is hypothesized that acid precipitation is causing accelerated foliar nutrient leaching in south-eastern hardwood forests.

Language: English Descriptors: Tennessee; Pinus taeda; Pine needles; Chemical composition; Ozone; Acid rain; Magnesium; Mineral deficiencies; Growth; Photosynthesis; Net assimilation rate; Pollution Abstract: Under experimental conditions, the growth of loblolly pine (Pinus taeda L.) is often responsive to ozone at near- ambient concentrations. However, little is known of the biochemical changes associated with this or other pollutants. Loblolly pine seedlings in open-top chambers were exposed to combinations of ozone (sub-ambient, ambient, or twice-ambient), acidic precipitation (pH 3.8 or pH 5.2) and soil magnesium (0.15 or 0.32 microgram g-1 exchangeable Mg) for three growing seasons. The effects of these treatments were greater in foliage than in stems or roots. The largest treatment effect was a 50% decrease in the starch concentration of current-year foliage from the twice-ambient ozone treatment compared with current-year foliage from the sub-ambient ozone treatment. Responses to ozone were consistent with the hypothesis that ozone-induced growth reductions are associated with depletion of carbohydrate reserves resulting from injury compensation and repair processes or reduced carbon fixation or both. Addition of acidic precipitation, and to a small extent Mg, decreased sugar concentrations of tissues; however, this effect appeared to be mediated by nutrient addition rather than by acidity per se. Given the role of carbohydrates in plant resistance to environmental stress, the sensitivity of carbohydrates to experimental treatments demonstrates the potential for indirect effects of ozone, acidic precipitation, and soil properties on stress resistance. Non-carbohydrate constituents were largely unresponsive to the experimental treatments. These findings imply that tissue carbohydrate analysis may be useful for assessing the impacts of pollutants in forest ecosystems. 85 NAL Call.

Language: English Descriptors: Pinus ponderosa; Branches; Maturity stage; Growth chambers; Design; Acid rain; Ozone; Stress response; Measurement Abstract: The investigation of the effects of atmospheric pollution on metabolism and growth of woody species has long been hampered by the very difficult task of exposing mature individuals to controlled environments of air pollutants. This paper describes the design, construction, and testing of an alternative tool to whole-tree enclosures for measuring pollution response in mature woody tissue. The chamber is a new design, though not a new concept, and is referred to as a branch exposure chamber. Designed primarily for ozone and acid precipitation exposures (and used additionally for CO2 measurements), the branch exposure chamber incorporates four major parts: support structure, fan-air supply unit, charcoal filter unit, and exposure chamber. The exposure chamber is a 1.5-m long by 0.7-m diam. cylinder. The chamber is constructed of Teflon sheeting stretched over an aluminum frame; the aluminum frame is totally wrapped with nonreactive, aluminum-backed Teflon tape. Three zones in the chamber affect exposure of the experimental tissue: an initial buffer region for mixing, a main exposure region, and an exhaust frustrum. Aerodynamic testing of the chamber-mixing characteristics show that mixing is uniform and complete within the main exposure region. Thermal buildup within the chamber was a maximum of 3 degrees C under a wide range of ambient meteorological conditions. Based on current field trials of the chamber, material deterioration due to environmental variables (e.g., ultraviolet radiation, heat oxidants), is not expected to affect operation of the chamber for 24 mo. The BEC is inexpensive to build and operate, and represents a viable alternative to a whole-tree chamber. 88 NAL Call.

Language: English Descriptors: North Carolina; Pinus taeda; Seedlings; Acid rain; Ozone; Photosynthesis; Chlorophyll; Carotenoids; Leaf conductance; Stomata Abstract: The effects of acid rain and ozone exposure on loblolly pine (Pinus taeda L.) seedlings in the Piedmont of North Carolina were assessed over two exposure seasons (1987-1988). Direct effects and carryover effects of long-term exposure on the photosynthetic potential and photopigment concentrations of different needle age-classes were studied. Three half-sib families were grown in open-top field chambers and exposed to two acid rain treatments (pH 5.3 or 3.3) and five ozone exposures delivered in proportion to ambient concentrations (0.5X to 3.0X ambient) in a complete factorial design. Ozone significantly affected photosynthesis but there were no statistically significant effects of acid rain nor any ozone X acid rain interactions. In 1987, photosynthesis of the 1987 first-flush progressively diverged among the ozone treatments except between charcoal-filtered (CF approximately 0.5X ambient) and nonfiltered air (NF). At the end of the first season, photosynthesis was reduced 24% at 1.5X compared to CF and more than 80% at 2.25X and 3.0X. Chlorophyll and carotenoid concentrations were similarly reduced at elevated ozone exposures. In 1988, photosynthesis of the 1987 first-flush in the elevated ozone treatments remained lower. Early in the second season, the 1988 first-flush had a 25% to 50% lower photosynthetic potential at 2.25X and 3.0X compared to CF. This carryover effect on the photosynthetic potential before significant cumulative exposure was progressively smaller in the later 1988 flushes. In the late season flushes in the highest ozone treatments, photosynthesis was significantly higher than in the lower ozone treatments.

Language: English Descriptors: Minnesota; Michigan; Wisconsin; Acid deposition; Anions; Cations; Throughfall; Acid rain; Hardwoods Abstract: Ionic concentrations and fluxes were measured for 2 years in five northern hardwood stands along an acidic deposition gradient that extends from northern Minnesota (lowest deposition) to southeastern Michigan (highest deposition). Precipitation fluxes of H+, SO4(2-), and NO3- were, respectively, 340, 69, and 83% greater at the site with the highest deposition than at the site with the lowest deposition. No significant differences among sites were evident for precipitation fluxes of cations along the gradient. Fluxes of H+, SO4(2-), NO3-, Ca2+, and Mg2+ in throughfall increased along the gradient and were positively correlated with increased atmospheric inputs of H+, SO4(2-), and NO3- measured at the sites. Fluxes of SO4(2-) and NO3- in throughfall were greater than precipitation fluxes, indicating dry deposition in excess of any assimilation of these anions from precipitation. Dry deposition inputs of SO4(2-) increased from the northwestern to southeastern sites and were estimated to range from 23 to 49% of precipitation inputs. Precipitation acidity was neutralized by the canopy in all stands, but the amount of H+ retained by the canopy was significantly greater at sites with the greatest precipitation acidity. Throughfall fluxes of Ca2+ and Mg2+ in excess of precipitation fluxes were positively correlated with the canopy retention and deposition of H+ along the gradient. Increased throughfall fluxes of these cations were consistent with hypothesized increases in canopy leaching of cations with increased acidic deposition. Increased canopy leaching of Ca2+ and Mg2+, resulting from elevated acidic deposition, was estimated to represent as much as 6.2 and 12.9% of foliar contents of these cations, respectively. Although HCO3- and organic anions were found to play an important role in maintaining electroneutrality in throughfall along the gradient, strong acid anions increasingly dominated anionic composition of throughfall with increasing acidic deposition. 92 NAL Call.

Language: English Descriptors: Pinus echinata; Acid rain; Ozone; Pine needles; Foliar diagnosis; Glucose; Sucrose; Reducing sugars; Starch; Dosage effects Abstract: Shortleaf pine (Pinus echinata Mill.) seedlings grown in open-top chambers were exposed to several combinations of ozone (near zero, ambient, 1.7 X ambient, or 2.5 X ambient) in conjunction with acid rain (pH 3.3, 4.3, or 5.3) starting in August 1988. Needle samples from the first (89-1) and third (89-3) flushes of the 1989 growing season were analyzed for their glucose, sucrose, total reducing sugars, and starch contents. For the 89-1 flush (current-year needles), no differences in glucose, sucrose, or starch contents were observed among the various ozone exposures during 1989. However, needles exposed to 2.5 X ambient ozone exhibited higher levels of total reducing sugars compared with other ozone exposures for most of 1989. High H+ concentration (pH 3.3) increased glucose content (compared with pH 4.3 or 5.3) in the September sampling only. No significant differences were observed among ozone treatments for the total reducing sugars, glucose, or starch contents of the 89-3 flush (previous-year needles) for most of the sampling periods in 1990. However, the sucrose content was lower in needles receiving 2.5 X ambient ozone compared with other ozone exposures. Although high H+ concentration (pH 3.3) appeared to affect some carbohydrate components, there was no general trend observed. 97 NAL Call.

Language: English Descriptors: Europe; Pinus sylvestris; Deciduous forests; Mixed forests; Forest litter; Pine needles; Leaves; Decomposition; Soil organic matter; Chemical composition; Leachates; Acidification; Sulfur dioxide; Acid deposition; Soil pollution; Magnesium; Calcium; Losses from soil Abstract: Decomposing needle and leaf litter, from a pine (Pinus sylvestris L.) stand and a mixed deciduous woodland, respectively, were exposed to arithmetic mean SO2 concentrations of up to 50 nl l-1 (mm3 m-3) in controlled field-based experiments lasting up to 215 d. The objectives of the study were: (1) to evaluate whether SO2 concentrations, known to occur in parts of Europe, could alter the chemical composition of forest litter and leachates, and (2) to use such information to complement results obtained during microbiological studies (Wookey et al., 1991). Dry deposition of SO2 on the litter resulted in the production of sulphate during damp conditions or when the litter was moist. The formation of SO4(-2) and associated H+ ions led to cation exchange processes whereby Mg2+ and Ca2+ in particular were leached from the litter. This resulted in significant (P < 0.01) depletion of magnesium and calcium in both litter types, even at the lowest SO2 concentrations tested (15 nl l-1). Incomplete buffering by base cations resulted in acidification of leachates. The magnitude of cation leaching and depletion within the litter was not always linearly related to SO2 or leachate SO4(-2) concentrations, and the role of microbial processes and litter quality as modifiers of such responses is considered. 101 NAL Call.

Superphosphate was applied once only, at the start of each experiment. The duration of the experiments was from one to three years. The amount of P required to produce 90% of the maximum yield of each legume was used to estimate the comparative P requirements of the legumes at each harvest. Ornithopus spp. (O. compressus, O. perpusillus and O. pinnatus) required less P than Trifolium subterraneum, the most widely sown pasture legume in Western Australia. The P requirements of Medicago polymorpha varied with soil type when compared to that of T. subterraneum, M. polymorpha required less P on a soil with a neutral pH value, but had a similar P requirement on a more acidic soil. M. murex, generally required more P than T. subterraneum. In some experiments, the comparative P requirement of the different legumes varied for different harvests. At each harvest in each experiment, the relationship between yield and P concentration in tissue (internal efficiency curves) usually differed for different legumes. Presumably different legumes take up P from the soil at different rates within each harvest, and utilize the absorbed P differently to produce herbage and seed. The exceptions were that similar internal efficiency curves were measured for O. compressus and T. subterraneum in one experiment, and three cultivars of O. compressus in another experiment. 112 NAL Call.

A long-term research project was established to identify the processes controlling surface water chemistry and to evaluate the sensitivity of Loch Vale Watershed in Rocky Mountain National Park, Colorado, to acid precipitation. Using lysimeters, we estimated the concentration and flux of major solutes in the Oie and B horizons in an old-grown Engelmann spruce (Picea engelmannii Parry ex Engelm.) and subalpine fir [Abies lasiocarpa (Hook.) Nutt.] forest, and in an adjacent site disturbed by a snow avalanche. In the forested site, most solutes were highly concentrated in soil solutions during the initial stages of snowmelt, and concentrations declined rapidly to low levels in the first 4 to 6 wk of snowmelt. Surface water chemistry in Loch Vale Watershed is controlled principally by mineral weathering. During the early stages of snowmelt, however, the flushing of solutes, especially N, S, and C, from forest soils (which comprise only 6% of the study area) exerts an important influence. Rates of cationic denudation per unit area were 3.5 times higher in the forest (131 micromoles(c) m-2 yr-1) than in the whole watershed (38 micromoles(c) m-2 yr-1) probably because of H+ exudation from roots during nutrient uptake and the generation of organic acids in the forest soils. Rates of N mineralization and nitrification as well as concentrations of NO3 in the soil solution were higher in the second year after forest disturbance from a snow avalanche than immediately following the disturbance, indicating a delayed nitrification response. Significant amounts of NH4 and NO3 were temporarily stored in extractable forms in the soil during the first year after the disturbance. Although precipitation inputs and theoretical mineral weathering can explain the total annual solute flux from Loch Vale Watershed, the effects of forest soil solutes may be important during the initial stages of snowmelt and following large-scale disturbance. 124 NAL Call.

Language: English Descriptors: Pinus taeda; Seedlings; Pine needles; Plant morphology; Acid rain; Mists; Abnormal development; Water stress Abstract: Curly shaped needles developed on loblolly pine (Pinus taeda L.) seedlings grown in lysimeters in two greenhouse studies. Nearly 90% of the seedlings from five half-sib families developed curly needles when watered weekly with one of four acid rain solutions. No abnormal needles developed on seedlings from the same seed lots growing on an adjacent bench and watered daily. In a second study, curly needles developed within 2 weeks after seedlings were transplanted into the lysimeters. Weekly misting of the foliage significantly reduced the proportion of fascicles with curly needles. Results indicate that curly needle syndrome is induced by water stress during needle elongation and suggest that wetting the foliage decreases the strength of the fascicle sheaths. 130 NAL Call.

Language: English Descriptors: Ontario; New York; Hardwoods; Forest soils; Spodosols; Cations; Calcium; Magnesium; Potassium; Hydrogen; Aluminum; Acid rain; Deposition; Cycling; Soil chemistry Abstract: Annual nutrient fluxes within two forests exposed to acidic deposition were compared for a 1-year period. Calcium (Ca 2+) was the dominant cation in throughfall and soil solutions from tolerant hardwood dominated Spodosols (Podzols) at both Huntington Forest (HF), New York, and the Turkey Lakes watershed (TLW), Ontario. There was a net annual export of Ca 2+ and Mg2+ from the TLW soil, whereas base cation inputs in precipitation equaled outputs at HF. In 1986, leaching losses of base cations were five times greater at TLW than at HF. A higher percentage of the base cation reserves was leached from the soil at TLW (5%) than at HF (1%). Relative to throughfall, aluminum concentrations increased in forest-floor and mineral-soil solutions, especially at HF. The TLW soil appears more sensitive to soil acidification. Deposited atmospheric acidity, however, was small in comparison with native soil acidity (total and exchangeable) and the reserves of base cations in each soil. Soil acidity and base saturation, therefore, are likely only to change slowly. 131 NAL Call. No.: 64.9 Am3 Denitrification in subsurface environments: potential source for atmospheric nitrous oxide.

Language: English Descriptors: Canada; Air pollution; Sulfur dioxide; Deposition; Acid rain Abstract: Emission of sulphur dioxide (SO2) takes place in Alberta from tall stacks at natural sour gas or oil sands processing plants. The local quantities of sulphur (S) deposition on soil and any resulting soil acidification are poorly known. The main objective was to quantify S deposited by wet and dry deposition at distances from a large emitter (135 t SO2-S day-1) and determine the effect on soil pH. Crushed soil samples were set in containers under rain shelters without walls at sites varying in distance from the source (4 to 173 km). After 4 months a sandy soil had accumulated 24 kg total S ha-1 when comparing the nearest and farthest sites, but the value was only 4 kg ha-1 for an organic soil. During 5 months in the next year, lichen over a thin layer of sandy soil accumulated 3.5 kg total S ha-1. The three soils had slight but significant pH decreases near the source, and they all had much less sulphate compared to total S increase. Lysimeters were set at 9 sites for a 17-month period and wet deposition of S near the SO2 emitter was < 2 kg S ha-1. A sandy Brunisol had an estimated 19 kg total S ha-1 increase by dry deposition while there was an increase of 56 kg for a sandy loam Luvisol when comparing the site nearest the emitter to the most remote. In all, dry S deposition in the vicinity of the S source was approximately 5 to 70 times greater than the S deposition in rain and snow. Dry deposition S was found mostly as total S instead of sulphate and slight decreases in soil pH occurred. In the laboratory, four ground soils were exposed to an air stream containing 185 micrograms SO2 m-3 of SO2 for 30 days in a 0.15 m3 chamber. The soils sorbed from 23 to 77 micrograms sulphate-S g-1 soil with slight pH depression. In a similar experiment, blocks of intact lichen (5 cm deep) over sand (2.5 cm deep) received an air stream with 265 micrograms SO2 m-3 for 7 days. The soil layers retained 2.6 kg total S ha-1 with little of it as sulphate. Injection of SO2 (200 microgr 134 NAL Call. No.: QH545.A1E52 Deposition of atmospheric ammonia to moorlands.
