“…Although many studies has been conducted on the influences of black locust on soil physicochemical and nutritional properties (Danso et al 1995, Tateno et al 2007, Wang et al 2012, Zhao et al 2013, the reclamation of soil properties by black locust is still not well understood (Keskin & Makineci 2009, Yüksek 2012, especially in terms of microbial biomass and activity.…”

“…This tree species is characterized by an extensive root system (Zhou & Shangguan 2005) nodulated by diverse nitrogen-fixing Rhizobium communities, providing the host with an advantage over native species on poor soils, and increasing thoroughly the soil nitrogen content (Noh et al 2010, Qiu et al 2010, Cierjacks et al 2013). For these reasons, black locust is presumed to be a favorable tree species for soil reclamation and regeneration of disturbed sites, such as roadsides and former mine sites.Although many studies has been conducted on the influences of black locust on soil physicochemical and nutritional properties (Danso et al 1995, Tateno et al 2007, Wang et al 2012, Zhao et al 2013, the reclamation of soil properties by black locust is still not well understood (Keskin & Makineci 2009, Yüksek 2012, especially in terms of microbial biomass and activity.The purpose of the study was to investigate ), likely due to difficulties in the utilization of organic substrates by the microbial community.

© iForest -Biogeosciences and Forestry IntroductionSoil health and quality may be successfully monitored through the use of two microbial indexes: (i) the microbial biomass, which is defined by the living component of soil organic matter, excluding the macrofauna and plant roots; and (ii) soil microbial respiration (basal respiration), which is described by the respiration without the addition of an organic substrate to soil (Jenkinson & Ladd 1981, Alef 1995, Sparling 1997. The microbial biomass is small and labile as compared with other ecosystem components; however, because of its key role in the mineralization of nutrients such as C, N, P and S, it is considered a reliable indicator of changes in soil characteristics (Jenkinson & Ladd 1981, Powlson et al. 1987, Balota et al. 2003. Balota et al. (2013) report that changes in the microbial properties of soil may lead to important changes in soil quality, thus affecting nutrient cycling and plant development. Haris (2003) clearly affirmed that the microbial community serves as an indicator of the re-establishment of connections between ecological functions of the biota in disturbed ecosystems. Despite the large variations in mineralogy, soil texture and land use type, extreme environments usually show low organic matter and very low microbial biomass contents, which indicate poor soil quality and limited site productivity (Sparling 1997, Guénon et al. 2013.Soil basal respiration is a well-established parameter to be measured through the decomposition process, and it is defined as the overall activity or energy spent by the indigenous microbial pool (Anderson & Domsch 1990, Sparling 1997. Insam et al. (1991) argued that soil basal respiration reflects the availability of slow-flowing C for microbial permanence and is a measure of basic turnover rates in soil.Robinia pesudoacacia L. (black locust or false acacia) is a deciduous, broad-leaved, light-demanding, medium-sized pioneer tree ranging in height 20-25 m. Black locust is regarded as an invasive, non-indigenous species in many parts of Europe, such as Germany, Italy and Turkey (Ansin & Özkan 1997, Cierjacks et al. 2013. It is well-adapted to grow on different types of soil and environmetal conditions, though it avoids compacted or wet soils. Indeed, its demand for aerated soil is the reason why black locust can be primarily found in disturbed sites from poor to fertile soils (Sabo 2000, Cierjacks et al. 2013. Black locust shows a rapid growth and adaptability, for it has been utilized for soil conservation or fuel wood, as well as for early reforestation of barren soils at disturbed sites (Landgraf et al. 2005, Keskin & Makineci 2009, Noh et al. 2010). However, in Turkey it has been long cultivated as an ornamental plant and it can be currently found in schoolyards, roadsides or other marginal lands (Ansin & Özkan 1997). This tree species is characterized by an extensive root system (Zhou & Shangguan 2005) nodulated by diverse nitrogen-fixing Rhizobium communities, providing the host with an advantage over na...

“…No significant changes in soil microbial biomass carbon (C), carbon dioxide (CO 2 ) respiration, metabolic quotient, and microbial metabolic activity have been found among different successive tree plantings (Xu et al 2008;Liu et al 2012). In contrast, Wang et al (2012) observed that microbial biomass C and activities of saccharase and cellulase in soils decreased, but polyphenol oxidase increased with increasing black locust plantation age. The plantation age had no effect on the α-amylase activity.…”

“…The environmental impacts of plantations are garnering increased attention partly because fast-growing tree species can adversely affect soil carbon and nutrient pools, thereby changing microbial properties (Chen et al 2004;Xu et al 2008). Plantation conversions and plantation stand age can influence size, activity, and composition of soil microbial communities by altering ecosystem carbon allocations (Chen et al 2004;Högberg and Read 2006) and controlling soil carbon availability (Yarwood et al 2009;Zheng et al 2010;Yan et al 2011;Gong et al 2012;Wang et al 2012). Tree species have different impacts on soil microbial metabolic diversity and activity due to differences of tree traits, stand age, site preparation, and soil condition (Xu et al 2008;Liu et al 2012).…”

Purpose Although it is generally accepted that planting exotic plant species alters metabolic function of soil microbial communities, its temporal dynamic is often ignored when evaluating ecological effects of associated land use changes. To investigate the dynamic impacts of successive Eucalyptus planting on carbon metabolic activities of soil microbial communities, we studied community-level physiological profiles of soil microbial communities in different generations of Eucalyptus plantations. Materials and methods We studied community-level physiological profiles of soil microbial communities, using the Biolog™ Ecoplates incubation, in adjacent first (G1), second (G2), third (G3), and fourth (G4) generation Eucalyptus plantations that were, respectively, aged 3, 8, 14, and 19 years in Guangxi province, southern China. We used the 'space-fortime substitution' approach to investigate the impact of stand age of exotic Eucalyptus plantations on carbon metabolic diversity and activities of soil microbial communities. For each Eucalyptus plantation generation, three experimental plots were randomly selected. In each plot, one composite soil sample from 0 to 10 cm in depth was obtained for the analyses. Results and discussion Single carbon source utilization varied with Eucalyptus plantation stand age. Among preselected 31 carbon sources, utilization of 17 carbon sources changed significantly, which was best described by a quadratic function (ten carbon sources) and an exponential function (seven carbon sources). As a result, cumulative averaged metabolic activity and metabolic diversity of soil microbial communities showed quadratic and exponential changes relative to Eucalyptus plantation stand age. The order of cumulative averaged carbon metabolic activity and metabolic diversity were G1>G4, G3>G2 and G1>G2>G3, G4 (p<0.05), respectively. The factors contributing to carbon source utilization structure of soil microbial communities for different stand ages of Eucalyptus plantations were shrub richness, soil organic carbon content, microbial biomass carbon, C-to-N ratio, and N-to-P ratio. Conclusions Eucalyptus plantation stand age has inconsistent non-linear impacts on two aspects of soil microbial metabolic function: (1) quadratic impacts on carbon metabolic efficiency and (2) exponential impacts on carbon metabolic diversity. The decreasing carbon metabolic diversity has no significant impact on carbon metabolic efficiency during successive Eucalyptus plantings. The results show that the importance of assessing long-term impacts of land use changes on soil microbial communities from exotic plantations by quantifying multi-aspect non-linear changes on soil microbial metabolic function.

To identify why tree growth differs by afforestation type is a matter of prime concern in forestry. A study was conducted to determine why oriental arborvitae (Platycladus orientalis) grows better in the presence of black locust (Robinia pseudoacacia) than in monoculture. Different types of stands (i.e., monocultures and mixture of black locust and oriental arborvitae, and native grassland as a control) were selected in the Loess Plateau, China. The height and diameter at breast height of each tree species were measured, and soil, shoot, and root samples were sampled. The arbuscular mycorrhizal (AM) attributes, shoot and root nutrient status, height and diameter of black locust were not influenced by the presence of oriental arborvitae. For oriental arborvitae, however, growing in mixture increased height and diameter and reduced shoot Mn, Ca, and Mg contents, AM fungal spore density, and colonization rate. Major changes in soil properties also occurred, primarily in soil water, NO 3‐N, and available K levels and in soil enzyme activity. The increase in soil water, N, and K availability in the presence of black locust stimulated oriental arborvitae growth, and black locust in the mixed stand seems to suppress the development of AM symbiosis in oriental arborvitae roots, especially the production of AM fungal spores and vesicles, through improving soil water and N levels, thus freeing up carbon to fuel plant growth. Overall, the presence of black locust favored oriental arborvitae growth directly by improving soil water and fertility and indirectly by repressing AM symbiosis in oriental arborvitae roots.
