Soil microorganisms play vital roles in energy flow and soil nutrient cycling and, thus, are important for crop production. A detailed understanding of the complex responses microbial communities to diverse organic manure chemical fertilizers (CFs) is crucial agroecosystem sustainability. However, little known about response fungal nutrients CFs, especially under double-rice cropping systems. In this study, we investigated effects application combined CFs various fertilization strategies, such as no N fertilizer (Neg-CF); 100% (Pos-CF); 60% cattle (CM) + 40% CF (high-CM); 30% CM 70% (low-CM); poultry (PM) (high-PM), PM (low-PM) on communities' structure diversity, environmental variables, rice yield. Results showed that synthetic plus addition significantly increased fertility grain yield compared sole CFs' application. Moreover, changed community relative abundance fungi phyla Ascomycota, Basidiomycota, Mortierellomycota, Rozellomycota. The abundances dramatically differed at each taxonomic level, between manured non-manured regimes. Principal coordinates analysis (PCoA) exhibited greater impacts amendments than distributions. Redundancy dominant were positively correlated with pH, C (SOC), total N, biomass C, was strongly affected by SOC. Network explored positive relationships could increase their adaptability relevant environments. addition, structural equation model (SEM) shows relationship biomass, nutrients, SEM contents availability directly affect yield, while indirectly through production levels. Our results suggest altered biochemical traits counteracted some adverse fertilizer. Overall, findings research integrated a better approach improving health

Microorganisms, Journal Year: 2024, Volume and Issue: 12(6), P. 1252 - 1252

Published: June 20, 2024

Heavy-metal contamination in agricultural soil, particularly of cadmium (Cd), poses serious threats to soil biodiversity, rice production, and food safety. Soil microbes improve fertility by regulating organic matter plant nutrient accumulation, pollutant transformation. Addressing the impact Cd toxicity on fungal community composition, health, yield is urgently required for sustainable production. Vermicompost (VC) an fertilizer that alleviates toxic effects microbial biodiversity functionality improves crop productivity sustainably. In present study, we examined different doses VC (i.e., 0, 3, 6 tons ha−1) levels stress 0 25 mg kg−1) biochemical attributes, fragrant-rice grain yield. The results showed significantly reduced fertility, eukaryotic composition However, addition alleviated improved community; additionally, it enhanced relative abundance Ascomycota, Chlorophyta, Ciliophora, Basidiomycota, Glomeromycta Cd-contaminated soils. Moreover, soil’s chemical including pH, carbon (SOC), available nitrogen (AN), total (TN), biomass C N, compared non-VC treated under conditions. Similarly, application increased decreased uptake rice. One possible explanation plants amendments influence biological properties, which ultimately reduces bioavailability subsequently influences accumulation plants. RDA analysis determined leading species were highly related environmental attributes N strongly associated with variables. Thus, outcomes this study reveal use soils could be useful production safe utilization Cd-polluted soil.

Abstract The dung microbiome is a complex system that highly influenced by species and diet. This study characterized the bacterial fungal communities of five herbivore inhabiting National Park Zuid‐Kennemerland, Netherlands. selected were rabbit ( Oryctolagus cuniculus L.), cow Bos taurus horse Equus ferus caballus fallow deer Dama dama European bison Bison bonasus L.). We explored effects distinct digestive physiology (ruminants vs. non‐ruminants) diverse dietary preferences on microbial community composition dung.

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 3, 2025

Background Xinjiang is situated in an arid and semi-arid region, where abundant heat sunlight create highly favorable conditions for cotton cultivation. Xinjiang's output accounts nearly one-quarter of global production. Moreover, the implementation advanced planting techniques, such as 'dwarfing, high-density, early-maturing' strategies combined with mulched drip irrigation, ensures stable high yields this region. Despite these advancements, limited research has focused on microbial mechanisms fields employing methods. Results The bacterial phoD communities rhizosphere were predominantly composed nine phyla (i.e., Proteobacteria, Actinobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, Bacteroidetes, Rokubacteria, Firmicutes, Nitrospirae) five Planctomycetes, Firmicutes), respectively. Alpha diversity analysis indicated that medium yield field (MYF) exhibited higher richness indices compared to low (LYF) (HYF) fields. symbiotic network LYF revealed greater values average degree, number edges, modularity, suggesting a more complex structure both communities. Mantel test, RDA, PLS-PM model identified soil pH, electrical conductivity (EC), organic phosphorus (OP), available (AP), total nitrogen (TN), biomass carbon (MBC), clay content main driving factors influencing changes community structure. Conclusion These findings provide theoretical basis future aimed at improving quality yield.
