    Effects of acid atmospheric deposition on the chemical composition of loess, clay and peat soils under forest in the Netherlands

    In addition to a survey of the soils under 150 forest stands on non-calcareous sandy soils, the chemical composition of the soils under 40 stands on non-calcareous loess soil, 30 stands on non-calcareous clay soils and 30 stands on oligotrophous peat soils have been examined, to assess the current status with repect to acidification and eutrophication, and the provide data for further studies. Only the clay soils are not yet seriously affected by the atmospheric inputs. The loess soils are generally considerably acidified, except the alluvial loess soils. The peat soils show a considerable eutrophication, especially in the topsoil, whereas anthropogenic acidification can hardly be separated from their natural acidity. Most investigated heavy metals show elevated concentrations, both in the humus layer and in the top soil, but serious pollution is not found.

    An overview is given of three dynamic soil acidification models for application on different spatial scales. NUCSAM, the model for the local scale, was validated on data from two intensively monitored research sites. Results of annual average soil solution concentrations and fluxes calculated with the validated NUCSAM model agreed well with those of the national-scale model RESAM and to a lesser extent with those of the European-scale model SMART. Various deposition scenarios for SOx, NOx and NHx on soils were evaluated with the three acidification models.

    A one-layer (SMART) and a multi-layer (RESAM) soil acidification model with temporal resolutions of one year and a multi-layer model with a resolution of one day (NUCSAM) were applied to an intensively monitored spruce site in Solling, Germany. The major aim was to study the influence of model simplifications and reduction of temporal and vertical resolutions on the simulation of soil solution concentrations. Results showed that all the models were able to simulate most of the concentrations reasonably during the examined period (1973-1989). However, the one-layer model, SMART, had difficulties in simulating strong changes in soil solution concentrations owing to a lower retardation in the soil system.

    In deze studie wordt aan de hand van twaalf boslocaties op zandgronden, die gedurende de periode 1992-1997 zijn bemonsterd, gekeken of er trends in de tijd zijn aan te tonen. De verwachting is dat het verwachte effect van beleidsmaatregelen is aan te tonen in de chemische samenstelling van naalden, bodemvocht en grondwater. De bestudeerde periode blijkt erg kort; gevonden trends kunnen sterk worden beonvloed door extreme jaren. Hierdoor kan een significante toename worden gevonden waar een afname wordt verwacht. Dit was bij NO3- en Al-concentraties in het bodemvocht het geval. Voor het Ca-gehalte in de naalden, de Ca-concentratie, de SO4-concentratie en NH4-concentratie in het bodemvocht zijn overeenkomstig de verwachting significante afnamen gevonden en voor de pH een significante toename. Meer duidelijkheid over trends in de tijd kan pas na een langere periode van monitoring worden verkregen.

    In een natuurgebiedje in de Gelderse Vallei is onder een klein dennebos, dat op een infiltratieprofiel ligt, sterk verzuurd grondwater aangetroffen. Het ligt voor de hand dat de atmosferische depositie van zure en verzurende stoffen hiervoor verantwoordelijk is. Om te zien in hoeverre dit inderdaad het geval is en welke verschillen er zijn met de depositie in een loofbos is een onderzoek verricht naar de aard en de omvang van de depositie in een klein dennebos en in een amerikaans eikenbos.

    Impact of acid atmosphere deposition on soils : field monitoring and aluminum chemistry

    The effect of acid atmospheric deposition on concentrations and transfer of major solutes in acid, sandy soils was studied. Emphasis was given to mobilization and transport of potentially toxic aluminum. Data on solute concentrations and fluxes in meteoric water as well as soil solutions were obtained from intensive monitoring programmes conducted at a number of sites in northwestern Europe and North-America. Specific hypotheses were tested in laboratory experiments.

    Atmospheric acid inputs dominated total acid loads in nearly all soils studied. This was particularly true for forest soils in the Netherlands, due to an extreme dry deposition of (NH 4 ) 2 SO 4 in the forest canopy. Input of (NH 4 ) 2 SO 4 may acidify the soil, due to NH 4 assimilation, or nitrification of NH 4 and subsequent leaching of NO 3 .

    In soils rich in weatherable minerals, mobilization of base cations dominated acid neutralization, so that percolation water was buffered at relatively high pH values and the mobility of aluminum was low. In these soils the mobilization and transport of aluminum was mainly driven by organic acids, which is consistent with the podzolization theory. However, in soils depleted in weatherable minerals (e.g. most of the acid, sandy soils in the Netherlands), mobilization rates of base cations were too low for a substantial neutralization of atmospheric acidity, so that pH values of the percolation water were often low enough to cause a significant mobilization of aluminum. In these soils the atmospherically derived strong acid load was almost fully neutralized by aluminum dissolution. Much of this dissolved inorganic aluminum is currently lost to the groundwater.

    Although aluminum is abundant in soils only a minor fraction, largely consisting of non-silicate organically bound aluminum, formed in the course of soil development (podzolization), was readily dissolved. The current rapid and irreversible depletion of this fraction in many acid, sandy soils of the Netherlands constitutes a drastic change in soil genesis. Depletion may eventually also result in reduced acid neutralization, due to decreased dissolution of aluminum.

    The aluminum solubility control varied with soil depth. Surface soil solutions were highly undersaturated with respect to gibbsite solubility, whereas saturation was approached in the subsoil. Possibly, the low aluminum solubility in the surface soil was controlled by an exchange type equilibrium with organic soil aluminum. Insight in the aluminum solubility control in soils is not only relevant for improving our understanding of the aluminum chemistry in soils per se, but it may also help explaining the aluminum chemistry of surface water in mountainous catchments, where soil solutions may reach the stream via different flowpaths through the soil, depending on hydrological conditions.

    Impact of acid atmospheric deposition on soils : quantification of chemical and hydrologic processes

    Atmospheric deposition of SO x , NOx and NHx will cause major changes in the chemical composition of solutions in acid soils, which may affect the biological functions of the soil. This thesis deals with quantification of soil acidification by means of chemical budgets, kinetics of mineral weathering of aluminum and base cations, and simulation of soil acidification. Most results apply to an acid forest soil on the Hackfort estate, for which monitoring data were available from 1981 to 1987.

    Spatial variability of soil solution composition was found to be the dominant source of uncertainty in determining chemical budgets. Uncertainty in annual chemical budgets due to simulation of unsaturated soil water fluxes generally does not exceed 10%. A new method was developed for in situ measurement of unsaturated soil water fluxes at a similar accuracy as obtained by numerical simulation.

    Weathering of Al is the dominant process for proton buffering in acid soils. In dutch acid soils, the most reactive pool for Al is present in hydrated oxides, often in association with organic matter. On average the weathering rate of Al increases nearly proportional with (H +), and decrease strongly with increasing depletion of reactive Al. Total exhaustion of the reactive pool of hydrated oxides may become a problem in the coming century.

    A new column percolation technique was developed to measure weathering rates at controlled pH in absence of mechanical disturbance. In all cases base cation weathering rates from laboratory experiments were considerably higher than estimated ' from field mass balance studies. A yet unconsidered effect for explanation of this discrepancy, is the increase of weathering rate with (by approximation the square root of) the percolation rate. Moreover, evidence was found that assumed patchy coatings of secondary Al may be protective against weathering of Ca from plagioclases.

    The ILWAS model was adapted for simulation of soil acidification. The model proved to be appropriate to simulate annual budgets and seasonal variation of concentrations for all major components. Concentration peaks near the end of summer appeared to be overestimated, but also scarce field observations may be biased. The model seemed somewhat too crude to predict N-dynamics. The model was used to analyze the response of the soil system to 50% reduction of deposition, fertilization, and removal of forest vegetation. Scenario analyses, demonstrated that pH is not a sensitive indicator for changes in soil chemistry. Simple models, using large time steps, may be adequate to evaluate average annual changes of soil solution characteristics over periods of several decades.
