“…Such varying responses of microbial diversity can be attributed partly to the direct toxicity of the hydrolysis products of canola amendments [44][45][46]. In addition, the incorporated biofumigants modify soil nutrients and microhabitats, thereby affecting soil microbial growth and colonization [47,48] and contributing to the shift in soil bacterial and fungal community structure [13]. This is consistent with our results that exchangeable potassium and AP were the most important determining factors in shaping bacterial and fungal community structures.…”

“…This is consistent with our results that exchangeable potassium and AP were the most important determining factors in shaping bacterial and fungal community structures. Such microbial communities that survive and flourish at 1% amendment could be highly resilient to environmental stresses [49], resistant to pathogen colonization [50], and maintain soil health [8] because of the more clustered and firmly connected microbial communities [51]. Biofumigant amendment creates favorable growth conditions for many members of copiotrophs, including Bacillus and Clostridium [9,52,53].…”

Background Biofumigation is a non-chemical sustainable approach that reshapes soil microbiota to overcome challenges in way of continuous cultivation. However, the type and quantity of substrate have a significant impact on microbiota shifts and the subsequent success of biofumigation. Moreover, studies on the effects of biofumigant concentration in combination with fumigation duration on soil microbiota dynamics are very rare. Research methods We performed microcosm experiments to investigate how a biofumigant (Korean canola cultivar, HanRa) at various concentrations (0.5%, 1%, 2–4% w/w: biofumigant/soil) and fumigation periods (2–4 weeks) affects the soil bacterial and fungal communities. Subsequently, pot experiments employing two Korean canola cultivars (HanRa and YongSan) at 1% (w/w) were carried out. Results Illumina MiSeq analysis revealed that 2–4% biofumigant, regardless of incubation period, had a significant negative impact on microbial diversity and network complexity. In contrast, 1% biofumigant transformed the bacterial, fungal, and inter-kingdom networks into a highly connected and complex network without affecting microbial diversity. Bacillus, Clostridium, and Pseudomonas were the most highly stimulated bacterial genera in the biofumigated soils, whereas the abundance of Acidobacteria members was greatly reduced. The 2–4% amendments had substantially and more differentially abundant Fusarium than the 1%. Soil nutrition (e.g., pH, nitrate, ammonium, and exchangeable potassium), fruit yield, and weed suppression were enhanced in subsequent pot experiments. Of the nine soil chemical properties, phosphate and exchangeable potassium were the main factors influencing the microbial community assembly. Conclusions Optimized biofumigation-mediated increase in nitrate, ammonium, and potassium availability in the soil without causing any negative effects on soil microbial diversity indicates its potential as a preplant to improve crop productivity. This study contributes significantly to our understanding of how an optimal biofumigant can help ameliorate obstacles in continuous cropping. Graphical Abstract

“…(3) The relative importance (contribution) of different factors (altitude, SWC, RFC, SBD, land-use types, vegetation ages, irrigation, fertilization, block, and the interaction of block and type) on SOC variation was assessed using mixed-effects models. In the model, land management (land-use types, vegetation ages, irrigation, and fertilization), altitude, and soil properties (SWC, RFC, and SBD) were fitted as the fixed factors and block as a random factor (Shu et al, 2022). All the analyses were carried out in R (version 4.2.1).…”

Few studies have been conducted on the factors and distribution of soil organic carbon (SOC) in plantation forests in arid mountainous regions, especially in orchards. We aimed to unravel the SOC distribution among land‐use types and the effects of altitude gradients and rock fragment content (RFC) on SOC accumulation and sequestration in the Upper Min River Arid Valley, China. The differences in SOC distribution among land‐use types were quantified. The correlation analysis of SOC with various factors, such as altitude and RFC, was conducted. The variation percentage in SOC content and stocks was explained by the factors' contribution using mixed‐effects models. SOC distribution was characterized by high content and low stocks in native forests and shrubs, high content and high stocks in eco‐forest, and low content and high stocks in orchards. At the surface (0–30 cm), SOC content and stocks in orchards (cherry, plum, and apple) were significantly lower than those in eco‐forests. There was a significant positive correlation between altitude and SOC content at the surface but not at the subsoil (30–60 cm). With RFC increased, the surface SOC content decreased in native forests, shrubs, and eco‐forests, while it increased in orchards. Our results suggest that land management is the main factor controlling the variation in SOC distribution. Enhancing the surface SOC stability in orchards by land management is a priority for soil carbon pool management in the Arid Valleys.

“…Generally, fertilization management regimes can affect the soil microbial diversity (Rodriguez-Berbel et al, 2020;Guo et al, 2019;Chen et al, 2017). A meta-analysis showed that organic fertilizer application improved the soil microbial diversity (Shu et al, 2022). Compared with CF, no obvious difference in bacterial alpha diversity and beta diversity was observed for CAOFCF treatments.…”

Combined application of organic fertilizer and chemical fertilizer (CAOFCF) is gaining more attention in sustainable agriculture production. However, it remains unknown whether short-term CAOFCF can improve soil properties and maize productivity simultaneously in a medium-productivity meadow-cinnamon soil. In this study, a 3-year (2019-2021) field experiment was established by arranging five treatments: (1) CF, applying chemical fertilizer alone; (2) OFCF1, 15% OF + 85% CF; (3) OFCF2, 30% OF + 70% CF; (4) OFCF3, 45% OF + 55% CF; (5) OFCF4, 60% OF + 40% CF. The results showed that short-term CAOFCF significantly increased topsoil aggregate stability with higher percentage of macro-aggregate and mean weight diameter in topsoil. Moreover, CAOFCF reduced soil bulk density and increased SOC sequestration in topsoil compared to CF, especially for OFCF3 and OFCF4. Although the soil bacterial diversity of CAOFCF treatments differed no significantly with CF, OFCF1 and OFCF2 obviously increased soil urease, sucrase, and acid phosphatase activities. Additionally, CAOFCF improved the relative abundance of Actinobacteria and Chloroflexi, as well as bacterial functional abundance. Compared with CF, OFCF1 and OFCF2 increased the root biomass, above-ground biomass, and grain yield (p<0.05), but the difference in these indexes among CF, OFCF3 and OFCF4 were not obvious. The correlation analysis indicated that there is no direct correlation between soil properties and grain yield. Nevertheless, the soil urease and sucrase activities were positively correlated with root biomass and root to shoot ratio, and root biomass and root to shoot ratio were positively correlated with above-ground biomass and grain yield. Overall, short-term CAOFCF with lower application amount of organic fertilizer (i.e. 1.36-2.72 Mg ha ) can improve topsoil physicochemical properties, soil enzymatic activities, as well as maize productivity in a medium-productivity cinnamon soil, the higher crop productivity was mainly attributed to the improved root system driven by urease and sucrase activities.
