“…Besides, the other dominant phyla were Acidobacteria , Chloroflexi , Gemmatimonadetes , Actinobacteria , Bacteroidetes , and Planctomycetes in the study area (Figure 1). These phyla were also found in the soils under various situations by other researchers (Wang et al, 2021; Wang, Li, et al, 2020; Wang, Yang, et al, 2020). Therefore, the results suggested that these dominant phyla in the Yellow River Delta are not unique, despite the soil being affected by salinization in this region.…”

Reclamation has been widely accepted as a means to restore abandoned lands. Most studies focused on the improvement of land reclamation explore soil nutrients and microbial activities. However, the effects of time since reclamation on bacterial communities of abandoned salt pans are still unclear. The object of our study are is to: (i) assess the successional change of soil physicochemical properties and bacterial communities in abandoned salt pans with different reclamation histories; and (ii) determine the main limiting factors on the improvement of soil quality in abandoned salt pans. The soils in farmland [reclamation time for blank (RTBL)] and six abandoned salt pans with 1 year (RT1), 2 years (RT2), 3 years (RT3), 4 years (RT4), 8 years (RT8), and 9 years (RT9) since reclamation were sampled to investigate the temporal variation of soil properties, heavy metal content, bacterial community composition, and diversity. Results showed that the soil bulk density (BD), total dissolved salt and median particle size (MMAD) decreased with the increase of time since reclamation, while soil nutrients (soil organic matter, total nitrogen, available phosphorus, available potassium) showed an opposite trend. The bacterial α‐diversity increased first, then decreased. Land reclamation enhanced the relative abundances of Acidobacteria, Chloroflexi, and Actinobacteria but reduced the relative abundances of Proteobacteria, Gemmatimonadetes, and Bacteroidetes. Compared with RTBL, the soil nutrients and bacterial community structure in RT1, RT2, RT3, and RT4 showed a significant difference. After 8‐9 years (RT8 and RT9) of reclamation, the soil nutrients and bacterial community structure in reclaimed abandoned salt pans showed RTBL. Therefore, time since reclamation is a vital driving force for restoring soil physicochemical properties and bacterial communities in abandoned salt pans.

“…Soil pH plays an important role in ecological restoration owing to its function in moderating the availability of plant nutrients. Severe soil disturbance inevitably causes changes in soil pH, usually resulting in a decreased pH [39]. A similar observation of an increase in soil pH after reclamation, from a near neutral value of 8.78 to a slightly basic status of 7.95, was also reported by Cheng and his collaborators (2018) [40].…”

Poor soil quality caused by salinity and sodicity is the main limitation on plant growth and crop production worldwide. This study focused on the change in the physicochemical properties of the coastal saline-sodic soils of Yellow River Delta with different histories of reclamation. Soil samples representing six different reclamation times (RTs) were collected in two soil profiles (0-20 cm and 20-40 cm). The results showed that soil soluble salts (SSs) significantly decreased with increasing reclamation time, and the change were 32.9%-67.6% in the 0-20 cm layer and 39.0%-73.2% in the 20-40 cm layer, respectively. Based on non-liner fitting, the change regulation of SS with RT was expressed by the following functions:(R 2 = 0.93, p<0.01) in the 0-20 cm layer and SS = (R = 0.97, p<0.01) in the 20-40 cm layer, respectively. The other soil properties, such as bulk density, total carbon, total nitrogen, the ratio of carbon and nitrogen, soil organic matter, available phosphorus, and available potassium significantly improved with increasing RT, but EC and pH had the opposite trend. The change in the physical and chemical properties of saline-sodic soil was higher at 0-20 cm soil depth than at the 20-40 cm soil depth, indicating that the effect of reclamation on salinesodic soils occurs mainly in topsoil. In conclusion, reclamation has been shown to be an effective human activity in terms of improving fertilizer and inhibiting the salinity of saline-sodic soils.

“…Generally, soil microbial community composition and activities in the mudflats area could change with increasing reclamation time (Hua et al, 2017; Wang et al, 2020; Xie et al, 2017). Our previous study found a shift of Bacteroidota (formerly Bacteroidetes ), Methylomirabilota (formerly NC10 ), and Nitrospirota (formerly Nitrospirae ) phyla along soil profile and across different reclaimed sites (Zhang et al, 2021).…”

Coastal mudflats reclamation activities show a strong influence on soil properties and microbial community activity, which drive soil carbon and nitrogen cycling. Studies have found there is a shift of bacterial community with reclamation time. However, effects of reclamation time on the soil archaeal community are still largely unknown.Here, we determined soil properties and archaeal community in the soil profiles (0-15, 15-30, 30-45 cm) of different reclaimed sites with different reclamation ages (R12: 12-year; R38: 38-year; R68: 68-year; R100: 100-year) in Rudong County, Jiangsu, China. Soil archaeal communities were identified via Illumina high-throughput sequencing. Soil archaeal communities were dominated by two phyla, the Crenarchaeota (82.1-93.3%) and Thermoplasmatota (4.2-17.9%), which are associated with nitrogen cycle (Nitrosopumilaceae, Nitrososphaeraceae, and Nitrosotaleaceae) and organic carbon metabolism (Marine_Group_II), respectively. Ammonia oxidizing archaea showed a divergent response to the reclamation, i.e. Nitrosotaleaceae increased with reclamation time whereas Nitrosopumilaceae showed a decreasing trend. Soil total carbon, total nitrogen, pH, EC, C:N ratio, NO 3 À -N content, soil moisture, depth, and reclamation age determined archaeal community distribution in our reclaimed sites. Our findings suggest that both reclamation time and soil depth significantly shaped the archaeal community composition, and then in turn modulated soil carbon and nitrogen cycling in the reclaimed mudflats.
