Summary: The diversity of cropping systems affects the composition of soil microbial communities, particularly in the rhizosphere and endosphere. Diversified cropping systems recruit a more diverse bacterial community in the rhizosphere, while fungal species richness varies between different cropping systems.

Summary: Organic manure (OM) is an effective measure to improve acidic soils. The acid (ACP) and alkaline phosphatases (ALP) encoded by the bacterial phoC and phoD genes, respectively, are responsible for organic phosphorus (P) mineralization. This study explored the short-term influence of OM application on phosphatase activity and organic P-mineralizing bacterial communities in acidic soils, focusing on the effects of the maize rhizosphere. The results showed that the maize rhizosphere had a stronger impact on phosphatase activities and bacterial community structures compared to OM application. The phoD-harboring bacteria were more sensitive to both the rhizosphere effect and OM application, while the phoC-harboring bacteria were only influenced by the rhizosphere effect.

Summary: A Bacillus strain, identified as Bacillus aryabhattai strain LAD, was isolated from long-term maize colonization soil. The study showed that LAD had phosphate-solubilizing and nitrogen-fixing functions that benefited plant growth. The treatment with LAD culture significantly influenced the root system development of corn seedlings and the structure of rhizosphere bacterial communities.

Summary: Understanding the metabolic diversity in the rhizosphere soil of pecan plantations is crucial for plant protection and forest productivity improvement. This study used untargeted metabolomics and high-throughput sequencing to investigate the differences in metabolic profiles between rhizosphere and bulk soils and the relationship between metabolites and microorganisms in pecan plantations. The findings revealed significant differences in metabolite abundance between rhizosphere and bulk soils, particularly in plant secondary metabolites and lipids. The study also identified specific metabolic pathways and factors influencing the rhizosphere metabolic spectrum, providing new insights into the interactions between pecan trees and microorganisms.

Summary: This study investigated the effects of substituting chemical fertilizer with biogas slurry on the soil bacterial community and functional structure in an apple orchard. The results showed that the application of biogas slurry significantly increased soil organic matter, alkali nitrogen, and available potassium content, as well as the weight of apple fruit and the diversity of soil bacterial community. The study demonstrated that the proper ratio application of biogas slurry and chemical fertilizer can regulate the soil bacterial composition and functional structure through changes in soil nutrients.

Summary: Interplanting different green manure crops in litchi orchards in tropical regions of China effectively increases soil nutrients and reduces weed population. However, the choice of green manure crop should be based on soil conditions, as different crops have different effects on soil nutrient content. Intercropping with green manure crops enhances soil ammonium nitrogen and available phosphorus content, and promotes the abundance of beneficial microbial genera. Therefore, intercropping is an effective management measure in litchi orchards, but the selection of green manure crop should be considered based on soil conditions.

Summary: The presence of microplastics in terrestrial systems has been proven by many studies. This study investigated the influence of different types of microplastics on the bacterial communities in rhizosphere soil. The results showed that the microplastics had varying effects on the alpha diversities of the microbiota, and different types of microplastics may have different biodegradation pathways. Additionally, the microplastics had different impacts on the functional categories of the bacterial communities.

Summary: This study investigated the effects of a new water-saving device on the bacterial community and root system of tomato plants. Results showed that a smaller micropore group spacing (L1: 30 cm) promoted the development of tomato root morphology and increased the abundance of nitrogen and phosphorus metabolism genes in the soil. However, a lower capillary arrangement density (C2: one pipe for two rows) led to a decrease in bacterial community diversity and functional gene abundance, limiting nutrient absorption by the roots. The L1C2 treatment resulted in a stable bacterial community structure and improved root development, leading to higher tomato yield.

Summary: Little is known about the dynamics of P fractions and bacterial communities in the rhizosphere of legumes in karst soils. In this study, a field experiment was conducted to investigate P uptake, rhizosphere P fractions and bacterial community structure of soybean in response to P fertilization. Results showed that rhizosphere acidification during soybean cultivation led to changes in P fractions and bacterial community composition. Phosphorus fertilization further affected soil pH and different P fractions, leading to alterations in bacterial community composition, especially in soils without P input.
