“…In some soil horizons aqueous inorganic Al appears to come predominantly from the organically bound Al in the soil (Cronan et al 1986;Mulder et al 1989; Walker et al 1990;Dahlgren and Walker 1993), whereas in other soil horizons some form of amorphous, inorganic aluminum trihydroxide or aluminum silicate is more important (Driscoll et al 1985;Driscoll 1989;LaZerte 1989;Dahlgren et al 1990;van Grinsven et al 1992;Matzner and Prenzel 1992; Dahlgren and Walker 1993;LaZerte and Findeis 1994).…”

Partyzantów 27, 76-200 S³upsk E-mail: jonczak@apsl.edu.pl Abstract. During the years 2008-2009, at the £ysomice Forest Subdistrict (Forest District Leoeny Dwór, Regional Directorate of State Forest Szczecinek) comparative studies of lysimeter water chemistry were conducted in a 120-year-old beech stand and beech stand of similar age with an admixture of pine and spruce. Three zero-tension lysimeters were installed beneath the organic and humic horizons of Dystric Arenosols under the beech and pine canopies.Lysimetric water was collected after every rainfall, measured volumetrically, filtered and analyzed on pH and concentration of dissolved organic carbon (DOC), iron and aluminium.The chemical composition of leachates differed between beech and mixed stands. The pH of water from the organic horizon, on average for the entire study period, was 4.89 in the beech stand and 3.71 in the mixed stand. Lysimeter water from the humic horizon had an average pH of 4.43 and 3.73 for the beech and mixed stands respectively. The concentration of DOC and Fe and Al in the lysimeter water was higher in the mixed stand than in the pure beech. The quantity of DOC and Al leached during one year per unit of soil mass was similar in the both stands, and the amount of Fe was significantly higher in stands with pine admixture than in pure beech stands.

“…The importance of the organic Al pool (Al org ) has been addressed by many studies in Europe and North America where the climate is temperate and soil organic content is higher (e.g. Mulder et al, 1989;Walker et al, 1990;Berggren and Mulder, 1995). However, dissolution of the soil inorganic Al pool (Al inorg ) is also an important contributor to the Al concentration in these Chinese soils.…”

The mechanism controlling Al solubility in Chinese acidic forest soils is not clearly understood. This is the main limitation to the ability to generate adequate dose-response prediction models of the ecological effect of acid rain. To evaluate the relative significance of possible processes, soils and soil solutions from five forest catchments, located in southern and southwestern China, were collected and analyzed for chemical parameters. Monitoring showed that inorganic Al (Al i ) was the dominant fraction in most soil solutions; organic Al (Al o ) was usually less than 10% of total monomeric Al (Al a ). Aluminum fractions varied significantly between and within the different sites, though appearing to follow a similar pattern. Over the entire pH range of 3.6-5.6, the pAl (i.e. Àlog of the Al 3+ activity) closely correlated with solution pH, following regression slopes of 1.28 and 2.00 for upper and lower soil horizons, respectively. The variations in Al 3+ activity could not be explained satisfactorily using mineral dissolution equilibria. Partial least square (PLS) regression showed that soil acidity (quality) and ionic strength (intensity) of the solution were the main explanatory variables for the variation in the concentration of Al fractions. Aluminum in upper horizons originated from both organic and inorganic solid Al pools, while aqueous Al in lower horizons was dominantly of inorganic origin. Aluminum solubility was strongly influenced by cation exchange, especially in the upper horizon. In the upper horizon, ionic strength (I) had a greater influence on Al solubility due to cation exchange reaction. In the lower horizon, dissolution of inorganic Al pools by the elevated H + concentrations was the main Al release mechanism. So Al activity was more dependent on H + (or pH) in the lower horizon.
