Summary: The study found that mowing has different effects on fine root production and turnover in different types of grasslands. In artificially restored grasslands, mowing significantly increased root production and turnover, while decreasing root lifespan. However, in naturally restored grasslands, mowing had no significant effects on these parameters, possibly due to higher species diversity.

Summary: The purpose of this study was to investigate the shedding process and morphological traits of root litter from Chamaecyparis obtusa. Researchers developed a method for direct sampling of root litter in the field and collected data for 12 months. They found that the monthly amount of root litter varied significantly, but the morphological traits did not differ significantly among months.

Summary: A field experiment was conducted to investigate the impact of ridge tillage on halophyte fine root dynamics in abandoned farmlands. The results showed that ridge tillage significantly decreased root production and lifespan in the 0-1 mm diameter range, while increasing root mortality. However, there was no significant effect on roots within the 1-2 mm diameter range. Seasonal patterns in fine root production, standing crop, and mortality were observed due to changes in soil organic matter, water content, and salt content. These findings suggest that ridge tillage can enhance halophyte root growth and lifespan, and improve belowground productivity in saline-alkaline soils of abandoned farmlands.

Summary: This study evaluated the changes in carbon storage, fine root production, and turnover in tropical silvopastoral systems and found that tree biomass and soil organic carbon content were significantly higher in silvopastoral systems compared to open pasturelands. Fine root production differed significantly between different silvopastoral systems and was positively correlated with soil organic carbon content.

Summary: This study investigates the effect of tree species diversity on the functional characteristics of fine roots. The results show that increasing tree species diversity does not change the morphological characteristics of fine roots, but it increases their productivity and turnover rate.

Summary: This study aimed to examine the dynamics and functions of fine roots during root zone expansion and belowground carbon accumulation. The results showed that fine root biomass contributed over 60% to belowground roots, with a majority of 69.25% being dead fine roots. Fine root turnover rates ranged from 0.10 to 0.22 per year, with the fastest rate found in the Bruguiera forest. Root zone expansion rates ranged from 0.55 to 1.28 mm yr (-1), and were positively correlated with live fine root biomass in the upper 50 cm layer of sediment.

Summary: Fine roots are crucial for belowground carbon cycling in terrestrial ecosystems. This study investigated the dynamics of absorptive fine roots (AFRs) and transport fine roots (TFRs) and their responses to stand conditions and root density in a subtropical montane mixed forest. It was found that higher root density increased the production and mortality of fine roots, while lower root density resulted in faster turnover of fine roots. Furthermore, tree species diversity positively influenced AFR production but had no significant impact on TFRs.

Summary: This study investigated the impacts of site characteristics, seasonal variation, soil depth, and tree girth size on fine root biomass, productivity, and turnover in a sub-tropical sal forest ecosystem. The results showed that fine root biomass was significantly affected by tree girth size, decreasing with increasing girth size. Seasonal variation had a significant impact on fine root biomass, with the highest biomass during the rainy season and the lowest during winter. Fine root biomass was highest in the top soil layer (0-20 cm) at a distance of 1.0 m from the tree bole, decreasing with increasing soil depth and distance from the tree bole.

Summary: The study revealed that fine root production, biomass, and necromass were significantly influenced by slope position, while the fine root biomass/necromass ratio was significantly affected by vegetation type. The variations in these parameters were mainly explained by fine root nutrients and the interactive effects between fine root and soil nutrients. These findings suggest that fine roots responding to soil and root nutrient changes might serve as an adaptive mechanism to enhance plant nutrient acquisition in nutrient-poor karst ecosystems.

Summary: Integrated crop-livestock-forestry (ICLF) systems maximize land-use efficiency and sustainability by exploring synergistic interactions between soil, plant, and animals. This study investigated belowground dynamics in an ICLF system, focusing on the role of incorporating dead root material. The findings highlight the heterogeneity of root necromass accretion and decomposition in ICLF systems.

Summary: The study investigated the effects of stand density and pruning on fine root production and nutrient release in a 12-year-old Acacia mangium stand in Kerala, India. Results showed that fine root production was influenced by stand density, while turnover rates were not affected. Tree pruning had modest effects on tree growth and nutrient release patterns.

Summary: The study found that the fine root production and turnover of Reaumuria songarica are closely related to soil water content, and their annual input of carbon and nitrogen contributes to the increase in soil organic C and N storage, promoting soil property heterogeneity.

Summary: This study found that under full waterlogging conditions, both fine root growth and transpiration of Pinus thunbergii significantly decreased, while under partial waterlogging conditions, fine root growth increased significantly in the non-waterlogged top soil. After 8 weeks of waterlogging, transpiration recovered to no significant difference compared to the control group, mainly attributed to the increase in fine root growth in the non-waterlogged top soil.

Summary: This study estimated fine root production (FRP) in the Amazonian peat swamp forest by using repeat photographs of roots from in situ transparent tubes. The results showed that FRP decreased with depth and was the highest during the dry season. This study demonstrates that minirhizotrons can be used as a low-disturbance method to estimate FRP in tropical forests and peatlands.
