“…They also undoubtedly reflect plant-dependent interactions. These may include species-specific interactions, such as those between actinorhizal or legume species (Ohtonen and Väre, 1998;Smolander and Kitunen, 2002;de Neergaard and Gorissen, 2004) and their symbionts, or more general interactions, such as those resulting from inputs of organic matter (Kent and Triplett, 2002). Similar conclusions have been drawn for successional patterns associated with glacial retreat (Ohtonen et al, 1999;.…”

Patterns of microbial colonization and interactions between microbial processes and vascular plants on volcanic deposits have received little attention. Previous reports have shown that atmospheric CO and hydrogen contribute significantly to microbial metabolism on Kilauea volcano (Hawaii) deposits with varied ages and successional development. Relationships between CO oxidation and plant communities were not clear, however, since deposit age and vegetation status covaried. To determine plant-microbe interactions in deposits of uniform ages, CO and hydrogen dynamics have been assayed for unvegetated tephra on a 1959 deposit at Pu'u Puai (PP-bare), at the edge of tree 'islands' within the PP deposit (PP-edge) and within PP tree islands (PP-canopy). Similar assays have been conducted for vegetated and unvegetated sites on a 1969 Mauna Ulu (MU) lava flow. Net in situ atmospheric CO uptake was highest at PP-edge and PP-bare sites (2.2 ± 0.5 and 1.3 ± 0.1 mg CO m À2 day À1 , respectively), and least for PP-canopy (À3.2 ± 0.9 mg CO m À2 day À1 , net emission). Respiration rates, microbial biomass and maximum CO uptake potential showed an opposing pattern. Comparisons of atmospheric CO uptake and CO 2 production rates indicate that CO contributes significantly to microbial metabolism in PP-bare and MU-unvegetated sites, but negligibly where vegetation is well developed. Nonetheless, maximum potential CO uptake rates indicate that CO oxidizer populations increase with increasing plant biomass and consume CO actively. Some of these CO oxidizers may contribute to elevated nitrogen fixation rates (acetylene reduction) measured within tree islands, and thus, support plant successional development.

“…In fact, in the present study, water-extractable organic matter was relatively higher in soils from beech plantations (30-year-old) than in the native forest. The elevated C-mineralization rate observed for the Norway spruce soil suggests that efficient microbial communities were adapted or were specific for this plant material in the plot and/or that labile organic compounds were more available despite acidic conditions [3,16,41]. Taking into account the bulk production of CO 2 -C in mg per kg of soil, the native forest plot mineralized more carbon than the other plots, suggesting that both the quality and quantity of organic matter have to be considered as main parameters controlling organic matter biodegradability and mineralization.…”

-In the Breuil-Chenue experimental site (Morvan, France), the native forest, a 150-year-old coppice with standards dominated by beech was partly clear-cut thirty years ago and replanted with several tree species. Soil samples were collected from the A 1 horizon, in the 0-5 cm layer of the preserved native forest and three plantations: European beech, Douglas-fir and Norway spruce. Aliquots of 0-2 mm sieved soils were incubated for 40 days under laboratory conditions (15 • C, water-holding capacity). Carbon-mineralization was monitored; mineral nitrogen, water-extractable organic carbon and mineral elements were determined before and after the incubation. The release of CO 2 decreased in the order: spruce > native forest > beech > Douglas-fir, whereas nitrogen net mineralization decreased in the opposite order. Douglas-fir and beech soils were characterised by high nitrification activity and high solubilization of Ca, Mg, and Mn. Native forest and spruce soils were characterized by low nitrification activity, high carbon-mineralization and high solubilization of Fe and Al.forest tree species substitution / topsoil organic matter / biodegradability / nutrient availability / carbon and nitrogen mineralization Résumé -Effet de la substitution des essences forestières sur la biodégradabilité des matières organiques et la disponibilité des éléments majeurs dans les horizons superficiels d'un sol tempéré. Il y a 30 ans, dans le site atelier de Breuil-Chenue (Morvan, France), la forêt native, un taillis sous futaie de 150 ans à dominante de hêtre, était partiellement coupée à blanc, puis replantée avec diverses essences. Des échantillons de sol ont été prélevés dans l'horizon A1 (0-5 cm) sous la forêt native préservée et les plantations de hêtre, Douglas et épicéa.

“…The components can be accumulated in lower parts of the soil profile being the basis of some soil-forming processes, or can leach to the ground and surface waters (Kalbitz et al 2000;Yano et al 2004;Dawson et al 2008; NorImpact of Scots pine admixture in European beech stand on dissolved organic carbon and nitrogen leaching from organic and humic horizons of Dystric Arenosols in Northern Poland J. Jonczak 1 , A. Parzych ström et al 2010). Annual fluxes of dissolved organic carbon, dissolved organic nitrogen and mineral forms of the element in leachates in relation to plant litterfall quantity and quality, and storage of the components in organic and humic horizons can be good indicators of the ecological state of an ecosystem and direction of processes taking place in the soil (Smolander, Kitunen 2002;Fröberg et al 2005;Evans et al 2006). The aim of the study was to compare the intensity of dissolved organic carbon (DOC), dissolved organic nitrogen (DON), ammonium nitrogen (NH 4 -N) and nitrate nitrogen (NO 3 -N) leaching from organic and humic horizons of Dystric Arenosols under beech and mixed pine-beech stands in northern Poland.…”

ABSTRACT:The effect of Scots pine admixture in European beech stand on the leaching of dissolved organic carbon (DOC), dissolved organic nitrogen (DON), nitrate nitrogen (NO 3 -N) and ammonium nitrogen (NH 4 -N) from organic and humic horizons of Dystric Arenosols was studied in northern Poland in [2008][2009]. Three zero-tension lysimeters under organic and humic horizons were installed in pure beech and mixed pine-beech stands. Water samples were collected after each rainfall, measured volumetrically, filtered and analysed. In each sample pH and concentrations of DOC, DON, NH 4 -N and NO 3 -N were analysed. Stronger acidification of leachates was observed in mixed stand compared to pure beech. About twice higher concentration of DOC and its fluxes per unit area were determined in mixed stand. The fluxes of DOC from unit mass of soil were less varied. In general, lower concentrations of DON, NH 4 -N and NO 3 -N as well as fluxes of the components (calculated in mg·kg -1 DM·year -1 and mg·m -2 ·year -1 ) were observed in mixed stand.
