“…As environmental variation is a key decisive factor of the distribution and abundance of microbes 35 . The relatively lower soil pH may decrease the bacterial diversity under continuous cropping systems, as soil acidity could change the stability of bacterial cell membranes and thus inhibits bacterial growth 36 , 37 . In addition, the high content of soil organic C in crop rotation systems, to some extent, likely influences bacterial diversity, activities, and community compositions.…”

Despite many studies on the influence of cropping practices on soil microbial community structure, little is known about ecological patterns of rare and abundant microbial communities in response to different tobacco cropping systems. Here, using the high-throughput sequencing technique, we investigated the impacts of two different cropping systems on soil biochemical properties and the microbial community composition of abundant and rare taxa and its driving factors in continuous and rotational tobacco cropping systems in the mountain lands of Yunnan, China. Our results showed that distinct co-occurrence patterns and driving forces for abundant and rare taxa across the different cropping systems. The abundant taxa were mainly constrained by stochastic processes in both cropping systems. In contrast, rare taxa in continuous cropping fields were mainly influenced by environmental perturbation (cropping practice), while governed by deterministic processes under rotational cropping. The α-diversity indices of rare taxa tended to be higher than those of the abundant ones in the two cropping systems. Furthermore, the network topologies of rare taxa were more complex than those of the abundant taxa in the two cropping systems. These results highlight that rare taxa rather than abundant ones play important roles in maintaining ecosystem diversity and sustaining the stability of ecosystem functions, especially in continuous cropping systems.

“…Related studies in acid forest river systems have indicated that organic carbon (C org ), iron (Fe), and aluminum (Al) may be the main binding elements of nano-, fine-, and medium-colloidal P and that the elemental composition may vary with the specific location within or between rivers. , However, detailed colloidal P fluxes remain almost blind spots in some areas of ecosystem research . In agricultural systems, colloidal carriers may be affected by farm management practices, such as irrigation, fertilization, and land-use types. , Compared to forest soils, agricultural soils usually have lower organic matter, higher inorganic mineral contents, and relatively stable seasonal input and outputs . Therefore, the composition and morphology of the colloids in agricultural soils may be very different from those in natural ecosystems, e.g., forest and steppe soils.…”

Nano and colloidal particles (1–1000 nm) play important roles in phosphorus (P) migration and loss from agricultural soils; however, little is known about their relative distribution in arable crop soils under varying agricultural geolandscapes at the regional scale. Surface soils (0–20 cm depth) were collected from 15 agricultural fields, including two sites with different carbon input strategies, in Zhejiang Province, China, and water-dispersible nanocolloids (0.6–25 nm), fine colloids (25–160 nm), and medium colloids (160–500 nm) were separated and analyzed using the asymmetrical flow field flow fractionation technique. Three levels of fine-colloidal P content (3583–6142, 859–2612, and 514–653 μg kg–1) were identified at the regional scale. The nanocolloidal fraction correlated with organic carbon (Corg) and calcium (Ca), and the fine colloidal fraction with Corg, silicon (Si), aluminum (Al), and iron (Fe). Significant linear relationships existed between colloidal P and Corg, Si, Al, Fe, and Ca and for nanocolloidal P with Ca. The organic carbon controlled colloidal P saturation, which in turn affected the P carrier ability of colloids. Field-scale organic carbon inputs did not change the overall morphological trends in size fractions of water-dispersible colloids. However, they significantly affected the peak concentration in each of the nano-, fine-, and medium-colloidal P fractions. Application of chemical fertilizer with carbon-based solid manure and/or modified biochar reduced the soil nano-, fine-, and medium-colloidal P content by 30–40%; however,the application of chemical fertilizer with biogas slurry boosted colloidal P formation. This study provides a deep and novel understanding of the forms and composition of colloidal P in agricultural soils and highlights their spatial regulation by soil characteristics and carbon inputs.

“…Also, the ratio between production and decomposition determines the thickness of the substrate layer on the forest floor (León & Osorio 2014). In this study, litter in CSP and QCP stands have a low degradation rate, which was the result of poor litter quality of CSP and high lignin content of QCP litter (Zarafshar et al 2020), which creates a thicker organic layer under these species compared to ASP, a nitrogen-fixing species with high litter nitrogen content (Llorente et al 2010). However, a faster decomposition under VNF and AVP forests in this study is probably due to a more attractive source for decomposers due to the lower C/N ratio, which resulted in thinner litter layer (Walmsley et al 2019).…”
