“…The increased N concentration in the soil of the alfalfa and maize rotation system is due to the activities of nitrogen-fixing bacteria and phosphate solubilizing microorganisms which are associated with the cultivation of alfalfa [32]. Our results showed that rotation increased the amount of N and organic matter in soil; the increase of these factors also promotes microbial diversity [33,34].…”

Soil microbial communities are involved in the maintenance of productivity and health of agricultural systems; therefore an adequate understanding of soil biodiversity plays a key role in ensuring sustainable use of soil. In the present study, we evaluated the influence of different cropping systems on the biodiversity of the soil bacterial communities, based on a 54-year field experiment established in Martonvásár, Hungary. Terminal restriction fragment length polymorphism (T-RFLP) fingerprinting technique was used to assess soil bacterial diversity and community structure in maize monoculture and three different crop rotations (maize-alfalfa, maize-wheat and the maize-barley-peas-wheat Norfolk type). No differences in richness and diversity were detected between maize monoculture and crop rotations except for the most intense rotation system (Norfolk-type). Although the principal component analysis did not reveal a clear separation between maize monoculture and the other rotation systems, the pairwise tests of analysis of similarity (ANOSIM) revealed that there are significant differences in the composition of bacterial communities between the maize monoculture and maize-alfalfa rotation as well as between wheat-maize and Norfolk-type rotation.

“…Proteobacteria was the most abundant in all treatments, accounting for ∼20% of the total number of OTUs (Figure 2A), and the Proteobacteria associated with symbiotic rhizobia was significantly more abundant in the SC cropping system. With the accumulation of soil OM and nutrients, the relative abundance of Proteobacteria increased (Freedman and Zak, 2015;Zeng et al, 2017). Acidobacteria was significantly less abundant in SC but significantly more abundant in the WS cropping system.…”

“…Soil fertility affects soil microbial community structure (Liu et al, 2014;Zhang et al, 2016). The increased OM and N in soil could promote bacterial diversity (Shen et al, 2014;Li et al, 2016;Zeng et al, 2017). An interesting phenomenon was observed in this experiment: in the SC and FS cropping systems, the contents of OM and N were very high, but the abundance and diversity of bacteria differed significantly, indicating that the abundance and diversity of soil bacteria may be related to other factors in addition to OM and N. The diversity of fungi under SC was significantly higher than that under rotation, and Hooper et al proposed that this might be related to the long-term accumulation of soil nutrients (Hooper et al, 2005).…”

“…Proteobacteria, Acidobacteria, and Actinobacteria were the main phyla in soybean continuous cropping (SC), soybean-corn, and cornsoybean rotation systems in all soil samples across succession. With the accumulation of soil organic matter (OM) and nutrients, the relative abundance of Actinobacteria decreased, while the relative abundance of Proteobacteria increased (Zeng et al, 2017). Lu et al (2011) found that increasing the crop rotation of legumes could release nutrients more quickly, leading to higher nitrogen (N) and potassium (K) contents and lower available phosphorus (P) content.…”

The predominant cropping system and management practices play an important role in soil physico-chemical properties and microbiome composition and diversity. This study analyzed the changes in soil fertility and the microbial community in four soybean-based cropping systems over 12 years. Amplification subsequencing techniques were used to compare soil community structures among the systems and identify significant positive and negative fertility factors. Soybean cropping favored the accumulation of OM and the available N, K DTPA Fe, Mn, Zn and Cu contents in soil but not fixed available P. The WS and CS cropping systems were conducive to the fixed available P, but they consumed OM, DTPA K, and Zn. The SC exhibited the lowest soil bacterial and archaeal abundance and diversity but high fungal abundance and diversity. The dominant Proteobacteria in the SC were significantly positively correlated with soil DTPA Fe and Mn. The dominant Actinobacteria were positively correlated with available P, DTPA Cu and Mn. The FS cropping system contained 764 unique bacterial species, 724 unique fungal species and the highest relative abundance of Protista. The FS had high microbial diversity, with high relative abundances of Bacteroidetes and Zygomycota and a significantly lower relative abundance of Actinobacteria. The Bacteroidetes were significantly correlated with available N, OM and DTPA Fe and negatively correlated with available P and DTPA Cu. Zygomycota was negatively correlated with available P and DTPA Cu. In the CS and WS, the soil bacterial abundance and diversity were moderate. The dominant Acidobacteria was significantly negatively correlated with soil DTPA, Fe and Mn. The CS exhibited the lowest fungal abundance and diversity. Furthermore, the relative abundance of Ascomycota was significantly improved in the WS and significantly positively correlated with available P and DTPA Cu. Decreases in the available P, K, DTPA Cu, and Mn of Vertisols greatly affect microbial community structure, and these nutrients regulate bacterial and fungal abundance and diversity. Compared to the SC, the FS, WS, and CS had more balanced soil fertility and microbial stability, but diverse cropping systems are most conducive to soil productivity. These findings are of great relevance for protecting the ecological environment.

“…Moreover, litter accumulation can alter biogeochemical nutrient cycles through its decomposition (Moretto, Distel, & Didoné, 2001;Wang, Xu, et al, 2017), as well as soil bacterial components and diversity (Hossain, Okubo, & Sugiyama, 2010;Zeng, An, & Liu, 2017).…”

Fencing is an effective and practical method for restoring degraded grasslands in northern China. However, little is known about the role of excess litter accumulation due to long‐term fencing in regulating abiotic environment and driving changes in community structure and function. We conducted a three‐year field experiment in two fenced grasslands in Inner Mongolia, and monitored light quantity, soil temperature, and soil moisture continuously, and determined community height, community aboveground net primary productivity (ANPP), and the relative dominance of different plant functional groups. Litter accumulation reduced light quantity and soil temperature but increased soil moisture. The regulating effects of litter accumulation on soil temperature and soil moisture fluctuated temporally and gradually weakened over the growing season. Litter accumulation also altered community vertical structure and function by increasing community height and ANPP. The increase in soil moisture increased the relative dominance of rhizome grasses but suppressed bunch grasses, thereby shifting bunch grass grasslands to rhizome grass grasslands. Our findings provide a potential mechanism for community succession in the context of litter accumulation in fenced grasslands and indicate that the vegetation and ecosystem services of degraded grasslands are improved after appropriate fencing.
