“…However, Kim et al (2009) reported that the SOC concentration in a 0 to 50 cm soil layer was minimally affected by thinning in a red pine (Pinus densiflora) stand after a one-year treatment. Akburak and Makineci (2016) also showed that thinning had no significant effect on SOC concentration in a coppice-originated European hornbeam (Carpinus betulus L.) stand in Turkey over a two year period. The increase of SOC after thinning during the short term may be explained by an increase in decomposition rates of forest floor.…”

“…Understanding the dynamics of SOC fractions and soil properties are more important when evaluating the effect of thinning on carbon pool stability and soil fertility. Furthermore, previous studies on soil labile carbon fractions have mainly focused on microbial biomass (Chen et al, 2015;Akburak and Makineci, 2016), while other SOC fractions based on physical and chemical methods were less studied. Therefore, further study on the variations of SOC fractions and soil microbial diversity in response to shortterm and long-term thinning is needed.…”

Forest management impacts on the soil carbon pool and soil properties. This study analyzed the changes of soil organic carbon (SOC) fractions, soil properties, and forest floor in a Chinese fir (Cunninghamia lanceolata) plantation after two years of thinning in Eastern China. The experiment consisted of three thinning treatments: unthinned, moderate thinned (stand stem density reduced by approximately 21%), and heavy thinned (stand stem density reduced by approximately 36%) stands. Concentrations of soil dissolved organic carbon (DOC), light fraction carbon (LFOC), and total SOC in the topsoil (0 to 20 cm) increased in the heavy thinned stands, and no significant effect for heavy fraction carbon (HFOC) was detectable in the soil profile. Some soil properties were also altered after thinning, which included a decrease in soil bulk density (BD), and an increase in soil temperature (ST), soil organic matter (SOM), total nitrogen (TN), available nitrogen (AN), available phosphorus (AP), available potassium (AK), and pH. The change of these soil properties mainly occurred in the topsoil layers (0 to 20 cm) in the heavy thinned treatment. The SOC and soil labile carbon fractions were positively correlated with ST, TN, AN, AP, and AK. Moreover, the increase of SOC fractions and the availability of soil nutrients maybe due to the increased input from an abundant well-decomposed forest floor after thinning. These results suggest that a 36% of thinning operations had a marked impact on the soil labile carbon pool and soil fertility in the topsoil in a Chinese fir plantation during a shorttime period. Thus, changes to soil carbon stability and soil fertility should be considered when developing forest management plans.

“…These practices have been implemented in Alabama's Bankhead National Forest (BNF), to mitigate the negative impacts of pest and disease outbreaks (Nobles et al, 2009), reduce fuel loads and accumulated ground flora on forest floors to promote growth of new forage and plants (Converse et al, 2006), increase forest productivity and enhance plant and animal diversity (Ganzlin et al, 2016). Forest productivities, plant nutrient concentrations, microbial richness, enzymatic metabolisms are possibly altered after fire events and forest thinning practices (Wic-Baena et al, 2013;Akburak & Makineci, 2015). Studies have reported an increase (Bååth et al, 1995;Klopatek et al, 1988) and/or decrease (Baar et al, 1999;Grogan et al, 2000), in short-lived bacteria proliferation and little or no increase in soil fungi (Jonsson et al, 1999) due to prescribed burning and/or tree thinning.…”

Prescribed burning and tree thinning are commonly used restoration practices for US forests management to increase forest productivity and enhance plant and animal diversity. The impact of these practices in Alabama's Bankhead National Forest (BNF) to soil microbial components and overall forest soil health are unknown. We hypothesized that microbial assemblages and enzyme activities are continuously changing in forest ecosystems especially due to management selections. Therefore, the objective of this study was to assess changes in microbial community compositions (fungal vs bacterial populations) via fatty acid methyl ester (FAME) profiling and several enzyme activities (β-glucosaminidase, acid phosphatase, arylsulfatase, β-glucosidase, xylanase, laccase, and manganese peroxidase) critical to soil organic matter (SOM) dynamics and biogeochemical cycling. In this forest, heavily-thinned plots without burning or less frequent burning treatments seemed to provide more favorable conditions (higher pH and lower C:N ratios) for C and N mineralization. This may explain a slight increase (by 12%) detected in fungi:bacteria (F:B) ratio in the heavily-thinned plots relative to the control. Thinned (lightly and heavily) plots showed greater ligninolytic (laccase and MnP) activities and lower β-glucosidase and β-glucosaminidase activities compared to the no-thinned plots probably due to increase depositions of woody recalcitrant C materials. We observed significant but negative correla

“…Forest functions, nutrient cycling, and chemical and biological properties of soils are altered after a fire event or thinning (Wic‐Baena et al. , Akburak and Makineci ). Successful restoration and regeneration of a forest ecosystem's structure and functions highly depend on the efficacy of nutrient cycling, and carbon is one of the elements involved in the cycles.…”

Ecosphere 8(12):e01962. 10. 1002/ecs2.1962 Abstract. Prescribed burning and thinning were implemented in an Alabama forest (Bankhead National Forest) as a management strategy to control pest and disease outbreaks and also to increase forest productivity. However, using fire as a control mechanism in this forest may alter soil nutrient cycling, soil organic matter (SOM), and soil microbial populations. There is the need for continuous research on forest ecosystems to bridge knowledge gaps in our understanding of SOM transformations and microbial processes in a repeatedly burned forest ecosystems. The objectives of this study were to assess and document the impact of prescribed burning and thinning on soil labile organic matter fractions, microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN), potential carbon mineralized (PCM), enzymatic activity, and energy (ATP) potentials. Labile organic carbon was isolated using the density method, whereas enzyme activities were determined as described in Bottomley et al. (Methods of soil analysis: part 2-Microbiological and biochemical properties, Madison, Wisconsin, USA: Soil Science Society of America, 1994). Microbial biomass C and N (MBC and MBN) were determined using the fumigation-incubation method. Treatment applications had some effects on MBC and MBN although these effects were not statistically significant (P ≤ 0.05). Light fraction carbon (LFC) and light fraction nitrogen (LFN) were significantly (P ≤ 0.05) affected by treatments. Irrespective of treatment, xylanase activity was the highest (3244 AE 327-5223 AE 567 lmol/g 24 h À1), whereas amylase activity was the lowest (12.57 AE 8.9-116 AE 42.8 lmol/g 24 h À1). Correlation analysis revealed that amylase, b-glucosidase, and NAGase correlated with particulate organic carbon (POC), particulate organic nitrogen (PON), and LFC, whereas cellulase, xylanase, and invertase had no correlation with the labile organic matter fractions. Compared to the referenced treatment plot, burned and thinned plots had reduced MBC, MBN, and increased PCM although this was not statistically significant. Although enzyme activities within plots were significant, no significant enzyme activities between plots were observed except with amylase. The lack of statistical significance on microbial activities, MBC, and MBN support our hypothesis that prescribed burning and thinning temporarily affected microbial indices, and these parameters are expected to return to pretreatment levels after a period of time.
