Iron (Fe) oxides are widely recognized to prevent the degradation of organic matter (OM) in environments, thereby promoting persistence carbon (OC) soils. Thus, discerning association mechanisms Fe and OC interactions is key effectively influencing dynamics extent C cycling Previous studies have focused on i) quantifying oxide-bound (Fe-OC) individual ii) investigating distribution adsorption capacity Fe-OC, iii) assessing redox transformation Fe-OC. Furthermore, widespread application high-tech instrumentation methods has greatly contributed a better understanding mechanism mineral assemblages past few decades. However, literature reviews comprehensively summarized Fe-OC distributions, associations, characteristics soil-plant systems. Here, contents among different environments reviewed. In addition, processes related OM occurring at mineral-organic interfaces also described. Recent highlighted that diverse occur between OC, with compounds adhering due their huge specific surfaces area active reaction sites. Moreover, we review for micro-interfaces. Lastly, developmental prospects coupled geochemical soil molecular- nano-scales outlined. The summary suggests combined advanced techniques should be used future research explore micro-interfaces situ descriptions assemblages. This need consider functional spatial complexity typical soil/sediment where occur.

Dynamics of soil aggregate‐related C‐N‐P stoichiometric characteristics with stand age and soil depth in Chinese fir plantations

Land Degradation and Development, Journal Year: 2022, Volume and Issue: 33(8), P. 1290 - 1306

Published: Feb. 1, 2022

Abstract Soil C‐N‐P stoichiometry offers an effective way to explore the balance, limitation, cycling, and distribution of chemical elements in Chinese fir plantations. This research aimed how soil organic C (C org ), total N (N tot P (P ) contents stocks, together with their stoichiometric ratios vary stand age (3, 9, 17, 26 years) as well layer (0–10, 10–20, 20–30, 30–40 cm) at aggregate scales plantations from Guangxi, China. For diverse ages, stability, , C/N, C/P, N/P ratios, remarkably declined when depth increased. Stand could influence characteristics soil, but such effect was more obvious 0–30 cm comparison that cm. In layer, C/P first rose then reduced during planting; meanwhile, highest levels be observed 17‐year‐old However, content stock, C/N ratio, were not related age. Overall, present helped understand C, N, dynamics within a chronosequence Also, it provided supplementary information for ecological global terrestrial ecosystems.

Assessing the impact of grazing management on wind erosion risk in grasslands: A case study on how grazing affects aboveground biomass and soil particle composition in Inner Mongolia

Global Ecology and Conservation, Journal Year: 2022, Volume and Issue: 40, P. e02344 - e02344

Published: Nov. 26, 2022

Soil wind erosion has consistently been a serious ecological problem in northern China. In recent decades, the grasslands of Inner Mongolia have suffered severe degradation due to overgrazing. After vegetation degradation, surface roughness and ability intercept sand decrease, resulting soil erosion. particles different sizes sensitivities erosion; those with smaller particle are usually more susceptible Therefore, composition can be an indicator local status risk. this study, we used typical as object set grazing intensities (i.e., low grazing, moderate high no grazing). We assessed risk grazing-induced grassland by analyzing changes composition. found that mainly occurred soils 0.075–0.5 mm. Low had little influence on aboveground biomass but increased topsoil compaction when compared grazing. High reduced biomass, while trampling caused fragmentation erosion, coarser texture. suggest practical management, occurrence appropriately reducing pressure, cessation is not best method for utilization restoration.
