Summary: Soil aggregates are vulnerable to agricultural intensification and are important for soil health and biogeochemical cycling. Fertilization practices impact the abundance of diazotrophic community behind soil aggregates, with organic fertilization promoting nifH gene abundance while chemical fertilization shows contrasting patterns. Organic fertilization also increases the complexity of microbial networks and the robustness of diazotrophic communities. Furthermore, the diversity and abundance of diazotrophic communities in soil microaggregates play a role in determining crop yields.

Summary: This study investigates the effects of nitrogen fertilization combined with biochar on sugarcane growth, rhizosphere soil properties, and microbial community composition. The results show that the combination of nitrogen fertilization and biochar promotes sugarcane growth and improves rhizosphere soil characteristics. The dose of biochar affects root-shoot growth responses, and higher biochar amendment results in an increase in soil nitrification potential. The application of nitrogen fertilization with moderate-dose biochar enriches specific bacterial communities, while soil pH, nitrate-nitrogen, and carbon/nitrogen ratio are key factors influencing soil bacterial community composition.

Summary: Bacterial communities in soil play a crucial role in maintaining the stability and functioning of soil ecosystems. The diversity of these communities is especially important in agroecosystems, as they are less stable and more dependent on external control. However, current agricultural practices such as plowing and synthetic fertilizer application can disrupt the richness and diversity of soil bacterial communities. Alternative farming methods, such as reduced tillage and organic farming, may offer a solution to this problem. Understanding the composition and diversity of soil microbiocenosis is essential for predicting the impact of agriculture and developing effective methods to enhance soil fertility.

Summary: Excessive nitrogen fertilization leads to the deterioration of soil microbiome. Reducing subsequent nitrogen supply and organic fertilization have effects on soil physicochemical properties, bacterial diversity, and community structure. The complexity and connectivity of bacterial co-occurrence network are also influenced. This study suggests that reducing nitrogen supply has a more positive impact on soil microbial community compared to organic fertilization in over-fertilized soil, and further investigation is needed for their long-term effects on soil microbiome.

Summary: This study investigated rare bacteria in the rhizospheres of natural watermelon and chimeric watermelon to understand the assembling processes of rare rhizobacteria during plant development and their effects on functional stability. The results showed that over 80% of total operational taxonomic units (OTUs) in the rhizosphere were classified as rare taxa, including transient, permanent, and conditionally rare taxa. Transient rare taxa had the highest richness, while conditionally rare taxa showed the largest variations along growth stages and played a significant role in assembling. Pairs of conditionally rare taxa with high asynchrony and similar functional potentials were identified in the rhizobacterial communities, indicating functional stability through redundancy. The number of pairs in the rhizosphere of chimeric plants was approximately two times higher than that in natural watermelon, suggesting that chimeric plants can enhance rhizospheric functions.

Summary: This study investigates the distribution and assembly of antibiotic resistance genes (ARGs) in typical agricultural soils under different fertilization regimes. The results show that organic manure application significantly increases the abundance and number of ARGs, as well as the abundance of mobile genetic elements (MGEs) associated with ARGs. Long-term organic fertilizer enriches opportunist and specialist ARGs in certain soil types. The assembly process of ARG profiles tends to be more deterministic in organically fertilized soils.

Summary: Understanding the differential fertilizer N fates among soil textures is crucial for optimizing crop nitrogen management. Two-year field experiments were conducted to quantify fertilizer N fates and evaluate their responses to N rates under different soil textures. The results showed that sandy soil had higher plant N accumulation from fertilizer and lower N use efficiency compared to loamy and clay soils. The denser texture of clay soil resulted in higher soil N residual but lower crop N recovery. Increasing N rates led to decreased N recovery and increased soil N residual on all three soils, with higher N responses observed in sandy soil. Therefore, adjusting crop N management strategies based on differential fertilizer N fates among soil textures is necessary.

Summary: Deficit irrigation (DI) is an effective technique to improve water use efficiency (WUE) in maize cultivation. A 3-year field experiment was conducted in Northeast China to investigate the combined effects of DI at the seedling stage and N fertilization on maize growth and yield. The results showed that DI positively impacted seedling growth and had similar or better effects on reproductive growth, grain yield, WUE, and NUE compared to well-watered plants. However, the effects of DI varied depending on the initial soil water content and precipitation. N fertilization compensated for the limited seedling growth under DI.

Summary: Soil fungi are critical in agricultural ecosystems, but little is known about their patterns and factors affecting rare and abundant subcommunities in response to continuous cropping. In this study, we investigated the diversity and structure of rare and abundant fungal subcommunities under different years of continuous chrysanthemum cropping. The alpha diversity of both rare and abundant subcommunities increased with continuous cropping years. Rare taxa showed higher dissimilarity than abundant taxa, and certain taxa were enriched in the 12-year cropping treatment. Soil rare fungi were mainly influenced by available nutrients and pH, while abundant fungi were influenced by soil total nutrients. The growth of chrysanthemum was significantly decreased in the 12-year continuous cropping system. Abundant fungi played key roles in chrysanthemum growth, despite the significant effects on rare fungi during continuous cropping.

Summary: Biodiversity plays a significant role in ecosystem multifunctionality, which depends on environmental conditions. However, the understanding of the functional importance of abundant and rare taxa in complex biocoenosis remains limited across different environmental gradients. This study collected and analyzed 152 independent soil samples from the steppes of northern China to investigate the relationship between soil multifunctionality and the diversities of abundant and rare species under changes in aridity and elevation. The results showed that the contributions of abundant and rare taxa to soil multifunctionality varied significantly with aridity and elevation levels. Abundant species richness had a positive effect on soil multifunctionality in less arid and higher elevation areas, while rare species diversity exhibited a strong positive relationship with soil multifunctionality in more arid and higher elevation regions. The findings emphasize the importance of aridity and elevation in shaping the contributions of abundant and rare taxa to soil multifunctionality.

Summary: This study aimed to evaluate the impact of long-term nutrient management practices on P fractions and P adsorption-desorption behaviour of an acid soil with a soybean-wheat cropping system. The findings revealed that amorphous Fe and Al, which play a significant role in P fixation, increased due to cultivation. The NPK+Lime treatment offered the most balanced approach, improving both crop yield and P uptake while effectively managing P dynamics in the soil. On the contrary, long-term application of NPK+FYM in an acid soil may result in faster P saturation of adsorption sites and increase the chances of leaching and eutrophication. Tailored P fertilization strategies should be developed to better utilize the PFe and PAl fractions and supplementing applied P.
