“…In recent years, much attention has been paid to understanding the impacts of timber harvesting on soil physical and chemical properties in general and on soil fertility in particular. Many studies have reported that timber harvesting deteriorates soil physical and chemical properties, including losses of organic matter, N (nitrogen), P (phosphorus), K (potassium), and minerals [6][7][8][9][10][11]; reductions in soil water holding capacity and porosity [12]; and increases in soil bulk density, soil erosion, and forest degradation [13][14][15][16][17]. Some others have explored the effects of forest cutting on biodiversity.…”

Abstract:The mixed Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), Masson's pine (Pinus massoniana Lamb.), and hardwood forest is a major forest type in China and of national and international importance in terms of its provision of both timber and ecosystem services. However, over-harvesting has threatened its long-term productivity and sustainability. We examined the impacts of timber harvesting intensity on soil physical and chemical properties 10 and 15 years after cutting using the research plots established with a randomized block design. We considered five treatments, including clear cutting and low (13.0% removal of growing stock volume), medium (29.1%), high (45.8%), and extra-high (67.1) intensities of selective cutting with non-cutting as the control. The impact on overall soil properties derived from principal component analysis showed increasing with a rise in cutting intensity, and the most critical impact was on soil nutrients, P and K in particular. Soil nutrient loss associated with timber harvesting even at a low cutting intensity could lead to nutrient deficits in this forest although most of the soil physical properties could be recovered under the low and medium intensities of cutting. These results indicate that clear cutting and the selective cutting of extra-high and high intensities should be avoided in this type of forest in the region.

“…Soil organic carbon (SOC) and total soil nitrogen (TN) were detected using a MAX CN Elemental Analyzer (Elementar Inc., Germany). Total soil phosphorus (TP) was calculated using the molybdenum blue colorimetric method using a UV/visible spectrophotometer after digestion in H 2 SO 4 -HClO 4 . Soil microbial biomass carbon (MBC) and nitrogen (MBN) were measured using the fumigation extraction method described by Vance et al [18], in which the carbon and nitrogen concentrations of non-fumigated soil samples served as estimates for dissolved organic carbon (DOC) and nitrogen (DON), respectively.…”

“…Therefore, understanding the causes underlying soil quality changes is important for sustainable N. longibracteata forest management and restoration. Due to its importance as a desirable tree for afforestation in China, a number of studies have been conducted focusing on soil fertility, soil physicochemical properties, and forest gap studies focusing on characteristics of fallen logs [4][5][6]. However, due to the complexity of soil ecosystems and lack of reliable experimental methods, studies of the soil microbial community associated with N. longibracteata have not yet been reported.…”

Soil microbial communities play a vital role in soil carbon and carbon sequestration in forest ecosystems. In this study, soils were sampled in Tianbaoyan National Nature Reserve in southeastern China from four Nothotsuga longibracteata forests, including a pure N. longibracteata forest (NF), N. longibracteata + hardwood mixed forest (NHF), N. longibracteata + Rhododendron simiarum mixed forest (NRF), and N. longibracteata + Phyllostachys pubescens mixed forest (NPF). Our objective was to precisely quantify soil physicochemical properties, microbial biomass, microbial communities, and to evaluate their interrelationships. We used biochemical measurements, a fumigation-extraction method, and phospholipid fatty acid (PLFA) analysis method to show that -except for pH and soil bulk density (SBD) -soil physicochemical properties differed markedly among the forest types. Microbial biomass carbon (MBC) and nitrogen (MBN) were highest in NHF soils, while the ratio of microbial biomass carbon to nitrogen (MBC:MBN) was highest in NRF and NPF soils. Moreover, the microbial communities of the four forest types exhibited distinct profiles: the highest total PLFA content and content of Grampositive bacteria (Gram(+)), Gram-negative bacteria(Gram(-)), and fungi were found in NRF. Additionally, NHF soil exhibited the highest actinomycetes content, while the highest protozoal content was found in NF soil. The analysis of individual PLFAs using principal component analysis (PCA) demonstrated a clear association of distinct soil PFLA characteristics for each forest type. In conclusion, the soil microbial community structure can be significantly influenced by changes in soil organic carbon (SOC) and MBN. Comparing soil microbial properties in different N. longibracteata forests can help us understand the influence of forest types on the structure of microbiota within a system.
