“…b). These values (0.11–11.31 mg g −1 ) were comparable to those in mangrove forests, agricultural lands, and tropical forests (1.5–13.5 mg g −1 ) (Wright and Anderson ; Lovelock et al 2004; Singh et al ; Wang et al ). However, the values were significantly higher than the GRSP concentrations in deserts (0.68–1.18 mg g −1 ) (Bai et al ) and semiarid grasslands (0.25–1.8 mg g −1 ) (Bird et al ; Rillig et al ).…”

“…The corn field and paddy wetland were disturbed by the annual cycle of soil preparation, planting, and harvesting, and the GRSP‐C/SOC ratios in those soils could reach up to 12–25% (Fig. b), which are higher than the reported ratios of 3–12% in tropical rain forests, mudflats, mangroves, and semiarid grasslands (Bird et al ; Lovelock et al ; Wang et al ). The GRSP‐C/SOC ratios should presumably have been no higher in the reed wetland than in the seablite wetland.…”

“…To some extent, the correlations could reflect the improvement of soil structure by GRSP. Previous studies have found inconsistent correlations between GRSP concentrations and sediment grain size in different ecosystems (Zhu et al ; Singh et al ; Wang et al ). Zhu et al () found that the concentrations of GRSP in the soils of five different land use types on Hainan Island were significantly and positively correlated with the percent sand in the soil, and significantly and negatively correlated with the percent silt and clay.…”

“…The role of AMF in conditioning soils is achieved by its metabolite glomalin. That role is believed to include enhancement of soil aggregate stability (Xie et al ), maintenance of soil fertility (Singh et al ), and enhancement of soil carbon capture (Rillig ; Wang et al ). Therefore, a proxy for AMF, glomalin‐related soil protein (GRSP), has been widely used to explore the role of AMFs in various ecosystems around the world (Lovelock et al ; He et al ; Spohn and Giani ).…”

Arbuscular mycorrhizal fungi (AMF) is presumably to be associated with carbon sequestration and nutrient acquisition through mineral weathering in wetland ecosystems. However, information on AMF-carbonweathering interactions is limited. Grain size, concentrations of nutrients, and the major components of 304 surface sediment samples and glomalin-related soil protein (GRSP) in 133 surface sediment samples were analyzed in various environments, including the upper delta plain wetlands (UDPW) and its adjacent shallow sea wetlands (SSW), to evaluate the relationship among the GRSP, carbon content, nutrients, and chemical index of alteration (CIA) in the wetlands of the Liaohe Delta (LHD). The concentrations of GRSP in surface sediments ranged between~0.11 and 11.31 mg g −1 , with an average of 2.30 AE 0.17 mg g −1 , and were significantly affected by the vegetation types. The ratios of organic carbon in GRSP (GRSP-C) to soil organic carbon (SOC) varied from 0.71% to 25.34%, with an average of 10.34% AE 0.52%, indicating that the GRSP was an important carbon pool in sediments, and the carbon dynamics in these wetlands were closely related to human activities. Moreover, the CIA values ranged from~18.97 to 68.75, and were significantly higher in the UDPW than in the SSW (p < 0.05), and were significantly correlated with the concentrations of GRSP (r 2 = 0.22 [r = 0.43], p < 0.01). Meanwhile, both the CIA and GRSP were significantly correlated with SOC, Total Nitrogen, and Fe (r 2 > 0.17 [r > 0.41], p < 0.01). The results indicate that AMF excursions in wetland ecosystems enhance carbon sequestration and mineral weathering, and in turn they alter retention of at least some nutrients.

Long‐term influence of phosphorus fertilization on organic carbon and nitrogen in soil aggregates under no‐till corn–wheat–soybean rotations

The role of P availability on soil C sequestration is poorly understood in no‐tillage production. The objective of this study was to examine the long‐term phosphorus (P) fertilization effect on soil organic C (SOC), N, and C:N ratio in soil aggregates at different depths in no‐till corn (Zea mays L.)‐wheat (Triticum aestivum L.)‐soybean (Glycine max L.) rotations. The experiment was conducted on low to medium P soils at Springfield and Milan, TN during 2013–2015 from 0–15 cm and from 0–5, 5–10, 10–15, and 15–30 cm in 2018 using Latin square design with five replications of five P rates (0, 29, 59, 88, and 117 kg P ha−1) applied annually. Bulk soil and aggregate sizes > 2, 0.25–2, 0.053–0.25, and < 0.053 mm were analyzed for SOC and N. Phosphorus rate of 88 kg ha−1 resulted in high soil testing P and had higher SOC and N than all other treatments on low P soil. However, over‐application of P at 117 kg ha−1 decreased SOC on low P soil. No response of SOC or N to P fertilization was observed on medium P soil. Application of 29 kg P ha−1 increased large macroaggregate (> 2 mm) weight. Concentrations of SOC and N were higher in microaggregates (0.053–0.25 mm) than the other aggregates. In conclusion, SOC and N stocks are increased on low P soils with appropriate P application, which is crucial for simultaneous improvements of soil C sequestration and crop yield.
