“…Nilsen and Strand (2008) found no significant difference in carbon storage related to thinning in a 33-year-old stand. However, Norway spruce stands were able to sequester a significantly higher amount of carbon in developing forest floor compared to oak as reported by Vesterdal et al (2002). The relatively high amount of litterfall (nearly 9,000 kg·ha -1 ) documented at the beginning (Slodicak et al 2005) was not confirmed during the following years of our study.…”

ABSTRACT:The effect of thinning on litterfall and decomposition of biomass was investigated in Norway spruce IUFRO thinning experiment (CZ-13), Czech Republic. The experiment was established in 1971 in an 8-year-old spruce stand on former farmland. Quantity and quality of litterfall and biomass from humus horizons were analysed in two treatments (1C -no thinning, 2T -heavy thinning at the young age). Under thinned stand, a lower amount of dry mass was observed compared to the control. Although mean total annual litterfall was the same in both treatments (5.3 Mg·ha -1 ), the observed trend indicates a possible effect of thinning on the higher rate of decomposition. With the exception of calcium (2002-2005 samples) we found the forest floor lower in nutrients and litterfall higher in nutrients in thinned plot compared to the control. Our results supported the theory that early thinning is an appropriate silvicultural strategy helping spruce to cope with growth conditions on sites naturally dominated by broadleaves.

“…We acknowledge that pseudo-replication is a limitation of the present study, as in many other paired-site and chronosequence studies (Sá et al, 2001;Vesterdal et al, 2002;O'Brien et al, 2003;Chen et al, 2004). Since each stand within a given region was separated by at least 100 m, we believe that the treatment effects are almost certainly more substantial than any possible site differences, given the severity of the treatments.…”

Land use and management Forest Soil chemical and biological processes Soil physical structure causes differential accessibility of soil organic matter (SOM), including carbon (C) and nitrogen (N) pools, to decomposer organisms and is an important determinant of SOM storage. Physical fractionation method of SOM in conjunction with elemental as well as isotopic analyses (C, N, δ 13 C, δ 15 N) of those soil fractions are used in this study to determine the land use and management-induced changes of SOM and associated processes in three adjacent sites of native forest (NF), first (1R) and second rotation (2R, including tree planting row (2R-T) and windrow of harvest residues (2R-W)) of hoop pine plantations in southeast Queensland, Australia. The results suggest that there is a greater accumulation of C and N in the light fraction (LF) of NF site than that of plantation sites (1R and 2R), and the C and N losses following conversion from mixed species NF to the single-species plantation are attributed to the reduction in C and N stocks for all physical fractions separated by wet sieving. In contrast, the C and N losses induced by the rotation practices (e.g., between 1R and 2R-T) are attributed to the C and N decreases in the LF and macroaggregates (250-2000 µm) only. The C and N increases upon the residue management (e.g., between 2R-W and 2R-T) are primarily attributed to the C and N increases in the LF and macroaggregates as well. Coupled with 30 soil chemical and biological parameters obtained in our previous studies, further principal component and multivariable regression analyses were conducted and the results showed that both the LF and macroaggregates were highly related to the status of C and N pools, the processes of N transformation and soil respiration, and the diversity of microbial communities, and thus could serve as diagnostic SOM fractions responsible for the changes of soil properties and processes within the tested ecosystem induced by the land uses and management practices. Knowledge of the interactive relationships between aggregate classes within SOM and soil chemical and biological processes in this study represents a further step towards diagnostically measuring and understanding important soil C and N processes in response to the land use and management changes in the soil ecosystems such as forests in subtropical Australia.

“…The study of soil carbon flux in the Loess Plateau is vital not only in supplying basic data for semi-arid areas, but also in providing a useful foundation for soil carbon sequestration assessment after land use change from an agroecosystem to a forest ecosystem, especially as a result of large area reforestation. Moreover, the afforestation of former farmlands has been acknowledged as a land use change that contributes to the mitigation of atmospheric CO 2 emissions (IPCC, 2000;Vesterdal et al, 2002). Forest and grassland are two main land use types after ′Grain to Green′ Program implementation in the Loess Plateau of China, and the result of that soil CO 2 emissions under different vegetation types were different in this area have been reported (Li Hongsheng et al, 2008).…”

Abstract:Carbon sequestration occurs when cultivated soils are re-vegetated. In the hilly area of the Loess Plateau, China, black locust (Robinia pseudoacacia) plantation forest and grassland were the two main vegetation types used to mitigate soil and water loss after cultivation abandonment. The purpose of this study was to compare the soil carbon stock and flux of these two types of vegetation which restored for 25 years. The experiment was conducted in Yangjuangou catchment in Yan′an City, Shaanxi Province, China. Two adjacent slopes were chosen for this study. Six sample sites were spaced every 35-45 m from summit to toe slope along the hill slope, and each sample site contained three sampling plots. Soil organic carbon and related physicochemical properties in the surface soil layer (0-10 cm and 10-20 cm) were measured based on soil sampling and laboratory analysis, and the soil carbon dioxide (CO 2 ) emissions and environmental factors were measured in the same sample sites simultaneously. Results indicated that in general, a higher soil carbon stock was found in the black locust plantation forest than that in grassland throughout the hill slope. Meanwhile, significant differences in the soil carbon stock were observed between these two vegetation types in the upper slope at soil depth 0-10 cm and lower slope at soil depth 10-20 cm. The average daily values of the soil CO 2 emissions were 1.27 mol/(m 2 ·s) and 1.39 mol/(m 2 ·s) for forest and grassland, respectively. The soil carbon flux in forest covered areas was higher in spring and less variation was detected between different seasons, while the highest carbon flux was found in grassland in summer, which was about three times higher than that in autumn and spring. From the carbon sequestration point of view, black locust plantation forest on hill slopes might be better than grassland because of a higher soil carbon stock and lower carbon flux.
