“…The soils are classified as Ferrisols derived from granite (Liu et al 2011). The intensive management practices, including annual fertilization, ploughing, and weeding with herbicide, have been conducted since 2001.…”

“…To maintain high productivity in Moso bamboo plantations and achieve the maximal economic benefits, increasing numbers of farmers are adopting intensive management practices, such as the regular removal of understory vegetation, ploughing, and fertilization (Liu et al 2011;Song et al 2011). Typically, conventional management regularly harvests bamboo stems and shoots, without any of the other management practices mentioned above (Liu et al 2011).…”

“…Typically, conventional management regularly harvests bamboo stems and shoots, without any of the other management practices mentioned above (Liu et al 2011). The intensive management practices increase bamboo production but reduce soil microbial functional diversity (Xu et al 2008;Zhou et al 2009), accelerate soil organic carbon mineralization (Zhou et al 2006;Jiang et al 2009), and may influence litter decomposition.…”

Aims The litter decomposition effects of N deposition in combination with management practices are still unclear. The aims of this study were to test the individual and interactive effects of the two factors on Moso bamboo leaf litter decomposition. Methods The experiment was conducted in Moso bamboo forests over a 24-month period and included three N addition treatments (low N, 30 kg N ha −1 yr −1 ;medium N, 60 kg N ha −1 yr −1 ; and high N, 90 kg N ha −1 yr −1 ) and two management practices (conventional management and intensive management). Results The low-N treatment significantly increased the annual decomposition rate, whereas the high-N treatment significantly decreased the annual decomposition rate (P<0.05). Intensive management alone did not significantly influence decomposition, but it amplified both the positive effects of the low-N treatment and the negative effects of the high-N treatment on litter decomposition. Intensive management weakened the positive effects of N addition on N loss but enhanced the positive effects on P loss during the early stage. Conclusions The effects of increasing N deposition in a plantation ecosystem were altered by the management practices, and these changes should be considered when estimating the biological effects of N deposition at regional and global scales.

“…The large variability in the effect of land use change on soil CH 4 and N 2 O fluxes was likely linked to specific site conditions, such as soil type, the type of land use change, and management practice used (Inubushi et al 2003;Lin et al 2012). Moreover, most of the existing studies have focused on the comparison of different types of land uses that have been converted for many years (Merino et al 2004;Iqbal et al 2009;Liu et al 2011); little research has been done to understand the dynamics of CH 4 and N 2 O fluxes and the mechanisms behind the observed changes during the initial stages after land use conversion.…”

Effects of land use conversion and fertilization on CH4 and N2O fluxes from typical hilly red soil

Land use conversion and fertilization have been widely reported to be important managements affecting the exchanges of greenhouse gases between soil and atmosphere. For comprehensive assessment of methane (CH 4 ) and nitrous oxide (N 2 O) fluxes from hilly red soil induced by land use conversion and fertilization, a 14-month continuous field measurement was conducted on the newly converted citrus orchard plots with fertilization (OF) and without fertilization (ONF) and the conventional paddy plots with fertilization (PF) and without fertilization (PNF). Our results showed that land use conversion from paddy to orchard reduced the CH 4 fluxes at the expense of increasing the N 2 O fluxes. Furthermore, fertilization significantly decreased the CH 4 fluxes from paddy soils in the second stage after conversion, but it failed to affect the CH 4 fluxes from orchard soils, whereas fertilizer applied to orchard and paddy increased soil N 2 O emissions by 68 and 113.9 %, respectively. Thus, cumulative CH 4 emissions from the OF were 100 % lower, and N 2 O emissions were 421 % higher than those from the PF. Although cumulative N 2 O emissions were stimulated in the newly converted orchard, the strong reduction of CH 4 led to lower global warming potentials (GWPs) as compared to the paddy. Besides, fertilization in orchard increased GWPs but decreased GWPs of paddy soils. In addition, measurement of soil moisture, temperature, dissolved carbon contents (DOCs), and ammonia (NH 4 + -N) and nitrate (NO 3 − -N) contents indicated a significant variation in soil properties and contributed to variations in soil CH 4 and N 2 O fluxes. Results of this study suggest that land use conversion from paddy to orchard would benefit for reconciling greenhouse gas mitigation and citrus orchard cultivation would be a better agricultural system in the hilly red soils in terms of greenhouse gas emission. Moreover, selected fertilizer rate applied to paddy would lead to lower GWPs of CH 4 and N 2 O. Nevertheless, more field measurements from newly converted orchard are highly needed to gain an insight into national and global accounting of CH 4 and N 2 O emissions.

“…Temporal variation in R S was generally attributed to changes in ST (Shi et al 2006) or SM (Davidson et al 1998;Xu and Qi 2001) alone or together (Chen et al 2010;Liu et al 2011) at the ecosystem level. Temperature can influence soil respiration mainly by affecting root activities, decomposition of plant litter and SOM and plant biomass production, leading to changes in C substrate availability for plant roots and soil microbes (Chen et al 2010;Luo et al 2012).…”

The pattern of soil respiration and its responsible factors are still unclear in subalpine ecosystems. In this study, we used a static chamber system to measure soil respiration in a primary Abies fabri (Masters) Craib forest, a secondary A. fabri forest and a clear-cut land on Gongga Mountain, east of Tibetan Plateau in China. Our results showed there were substantial diurnal and temporal variations in these three subalpine ecosystems. The diurnal coefficient of variation (CV) of soil respiration was lowest in primary forest (20.5%), and highest in clear-cut land (40.4%). Diurnal patterns of soil respiration were generally associated with soil temperature at 5 cm for all the three systems. The temporal CV was lowest in secondary forest (55.6%), and highest in clear-cut land (82.8%). Soil temperature at 5 cm depth was the major factor controlling 55-61% of temporal variation of soil respiration. The temperature sensitivity (Q10 value) was higher in clear-cut land (Q10 = 6.7) than that in primary forest (3.7) and secondary forest (3.0), indicating that soil respiration in clear-cut land was more sensitive to temperature change. Annual soil respiration was 3330.2 g carbon dioxide (CO 2 ) m −2 year −1, 2358.9 g CO 2 m −2 year −1 and 4162.8 g CO 2 m −2 year −1 for primary forest, secondary forest and clear-cut land, respectively. Our findings provided valuable information for understanding the effect of forest ecosystem change and land management on soil respiration in highelevation subalpine ecosystems.
