Summary: A two-year field experiment on Bt transgenic oilseed rape demonstrated that there were significant changes in the rhizosphere soil microbial community structure and diversity, particularly in relation to developmental stage, diversity, and evenness. The study showed that different transgenic lines might have a minor impact on soil microbial structure, with variations seen in consecutive seasons and at different growth stages.

Summary: Understanding the effects of plant roots on soil pore structure and microbial community is important for soil recovery and productivity improvement in mining areas. This study assessed the impact of taproot and fibrous root crops on soil physicochemical properties, pore structure, and microbial communities. The results showed that fibrous root crops were more effective in improving pore structure and enhancing microbial network development in reclaimed soil.

Summary: The study investigated the rhizosphere microbial communities associated with Verticillium wilt symptoms in two cotton cultivars. Diseased plants had a higher total fungal/bacterial biomass ratio and lower bacterial alpha diversity in their rhizosphere compared to healthy plants. The fungal alpha diversity differences depended on cultivars, and there were large differences in both fungal and bacterial communities between healthy and diseased plants.

Summary: Modern agriculture relies heavily on synthetic fertilizers, but nanofertilizers provide an innovative, efficient, and eco-friendly alternative. They release nutrients slowly to support plant growth and conserve beneficial microbiome diversity, although there are still challenges related to production, transportation, and dosage sensitivity.

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: The microbial communities in the soil surrounding plant roots (rhizosphere) are distinct from those in the non-rhizosphere soil due to root exudation and symbiosis with plant roots. However, little is known about the seasonal variations in these rhizosphere microbial communities, especially during the dormant season of cool temperate forests.

Summary: In a field experiment conducted in a reclaimed area along the coast of Zhejiang, China, it was found that after 3 years of Albizzia julibrissin plantation, rhizosphere soil salinity decreased, nutrients increased, creating a favorable habitat for bacteria growth, forming a complex co-occurrence network that promoted nutrient cycling.

Summary: Growing live mulch can be a cost-effective way to control weeds and enhance soil biological activity and microbial diversity in Bt cotton fields. Different mulch types have varied effects on soil biological activity, with some crops showing potential to improve soil biology and serve as alternatives to plastic mulch. Analysis of the soil metagenome data revealed the abundance of different bacterial phyla in mulch treatments, highlighting the potential of mulching to positively impact soil health and biodiversity.

Summary: Soil respiration is the largest carbon flux from terrestrial ecosystems to the atmosphere and partitioning the sources of soil carbon dioxide remains uncertain. Through observations and models, we determined that root + rhizosphere respiration, litter respiration, and soil organic matter-derived microbial respiration accounted for 20.1%, 21.8%, and 62.7% of total soil respiration, respectively. Precipitation was the most important factor influencing the proportions of these components, with higher root- and litter-derived soil CO2 fluxes in tropical forests compared to cold temperate and boreal forests. Accurate partitioning of the sources of soil CO2 flux will provide important insights for global carbon budgets.

Summary: Modern agriculture heavily depends on agrochemicals to increase crop production, but their indiscriminate use poses detrimental effects on plant growth and soil quality. To address these issues, the usage of plant biostimulants has emerged as an environmentally friendly approach to enhance crop productivity.

Summary: This study investigates the rhizosphere effect on soil organic carbon, nutrients, and soil microbial biomass in different forests in the central Himalaya. The results show that the rhizosphere significantly affects soil properties, with banj oak exhibiting a strong rhizosphere effect and chir pine showing a low rhizosphere effect. The rhizosphere effect decreases with increasing soil depth and is more prominent in the rainy season. The study suggests that the rhizosphere soil microbial index can be used to evaluate soil quality in temperate forests.

Summary: The study found that in Robinia pseudoacacia plantations at different stages of forest succession, root nitrogen and phosphorus resorption efficiencies initially decrease and then increase, while rhizosphere soil nutrient contents increase with stand age. Meanwhile, the diversity of rhizosphere soil microorganisms initially increases and then declines, with different microbial communities having advantages in different nutrient-rich restoration stages.

Summary: Legume-based intercropping, specifically rotational strip peanut/cotton intercropping, significantly increases the seed cotton yield and net economic returns without affecting the peanut pods yield. The physiological data indicate that intercropping enhances the leaf net photosynthetic rate, total biomass, and total nitrogen accumulation in peanut pods and cotton buds. Intercropping also increases the total protein and oleic acid contents in peanut kernels. Metabolomics and soil microbial community analysis reveal that intercropping influences the plant metabolic pathways and soil microbial composition and functionality. However, the beneficial effects of intercropping are partially counteracted by the introduction of a solid root barrier.
