“…Among the reclaimed soils, SL had greater Chao1 and Shannon indices than monocultural cropland, probably due to higher plant diversity in the SL (Kowalchuk, Buma, de Boer, Klinkhamer, & van Veen, 2002). A wide range of rhizosphere carbon inputs due to higher plant diversity in the SL contributed to the increase of microbial diversity in the soil (Lange et al, 2015; Meng et al, 2019). Furthermore, higher microbial diversity is often associated with greater ecosystem stability (McNaughton, 1994).…”

Understanding the impacts of different land‐uses on soil microbial communities is essential for maintaining soil health and sustainability in a desert‐oasis ecotone. Information on the microbial community composition of reclaimed soils under different land‐use types after several decades of reclamation are limited. The objective of this study was to investigate the impacts of reclamation of the non‐productive desert to productive lands on soil microbial community composition and identify the critical soil chemical factors associated with these changes. Soil samples were collected from a control (natural desert land [DL]) and reclaimed lands: cotton land (CL), grape land (vinyards) (GL), and shelterbelt (SL). Soil microbial community composition and diversity were determined by high throughput sequencing. The results showed that soil organic carbon (SOC), total nitrogen (N), phosphorus (P), potassium (K), and pH were significantly different between DL and reclaimed soils (CL, GL, and SL). Sixty years after reclamation, the CL contained a higher relative abundance of Actinobacteria, while the GL and SL contained a higher relative abundance of Acidobacteria. There were 541 operational taxonomic units (OTUs) shared by all the four land‐use types. The highest number of shared OTUs was found in the GL and SL. The variance observed in the bacterial communities in all land‐use types were mainly explained by SOC, followed by total N, total K, pH, and total P. Our results suggest that land‐use type change has significant impacts on soil bacterial community composition and diversity through modifications in soil chemical properties in desert‐oasis ecotone.

“…Winegrape cultivation is thus generally associated with increased fungal and bacterial diversity owing to the increased diversity of plants in the vineyard rows (Kowalchuk, Buma, de Boer, Klinkhamer, & Van Veen, 2002). Plant diversity and associated rhizosphere carbon input can help drive increased soil microbial diversity (Lange et al, 2015;Meng et al, 2019). Higher microbial diversity is often associated commonly linked to increased ecosystem stability (Delgado-Baquerizo et al, 2016).…”

Desertified land reclamation for the purposes of winegrape cultivation can profoundly alter the properties of the underlying soil and the microbial communities therein. Herein, we assessed the effects of such reclamation of non-productive desert land on the soil microbial communities associated with the resultant vineyards, and to identify key soil properties related to these changes. Soil was collected from natural desert land (DL) and from different reclaimed vineyard types: Cabernet Sauvignon (CS), Merlot (M), Chardonnay (C), and Italian Riesling (IR). High-throughput sequencing was used to assess microbial community composition and diversity in these samples. Significant differences in soil organic carbon (SOC), total nitrogen, available nitrogen, available phosphorus, and pH were detected when comparing soil from DL and reclaimed lands. CS, M, C, and IR soils exhibited higher relative Actinobacteria, Proteobacteria, and Ascomycota abundance, while DL soil exhibited higher relative Acidobacteria and Mortierellomycota abundance. In total, 165 and 55 bacterial and fungal amplicon sequence variants or operational taxonomic units (ASVs/OTUs) were shared across land use types. Following reclamation, soil bacteria ASVs/OTUs in CS, M, C, and IR soils rose to 2846, 3191, 7630, and 6373, respectively. Biomarkers of these different land use types were successfully identified via an LDA Effect Size (LEfSe) approach, while key soil properties including pH, SOC, and available nitrogen were found to be associated with these changes in microbial community structural composition following reclamation. As such, our data indicate that viticulture in desertified regions can enhance soil properties and microbial diversity, thereby supporting sustainable land use.

“…It also provides a basis to support the point of view, i.e., there is a difference in the litter decomposition rate between forest lands, which in turn affects the nutrient content of forest soil. Through the study, Meng et al [35] found that, after forest conversion, it can influence soil bacteria communities. Wan et al [36] studied on the effect of forest management methods on soil bacteria communities; they found that forest management method could affect soil bacteria community and soil nutrient.…”

The maintenance of drinking water safety is a major environmental issue. It is necessary to strengthen environmental protection in water source areas and establish good vegetation coverage. This study examined the effects of secondary forests transformation on chestnut forests on soil nutrient changes in the Fuji Reservoir, Anji County, Zhejiang province, China. Plots were set up in a chestnut plantation and a nearby secondary forest to measure the nutrient contents of soil samples that were collected from different soil depths. Differences of soil nutrient content from the two stands were significant at 0–20 cm soil depth. There were no significant differences in the contents of total phosphorus and total potassium between the two forests; however, the available phosphorus content in chestnut stands was 2.73 mg/kg higher than in secondary forests. Overall, the soil nutrient contents under chestnut stands were lower than those under secondary forests. Some of the soil surface is exposed due to the low diversity of the chestnut forest. The soil nutrients in the chestnut forest are usually carried and transferred in soil particle form and they become dissolved in the runoff during rainfall and lost, which explains the lower soil nutrient contents in the chestnut forest than the secondary forest. Therefore, for economic forests, such as chestnut forests, measures should be taken to protect understory vegetation and enhance soil and water conservation capacity, which is conducive to retaining soil nutrients.
