Microalgal biomass offers a promising biofertilizer option due to its nutrient-rich composition, adaptability, and environmental benefits. This study evaluated the potential of microalgal-based biofertilizers-microalgal Chlorella biomass, de-oiled microalgal (DMB), de-aqueous extract (DAEMB)-in enhancing lettuce growth, soil nutrient dynamics, microbial community composition. Lettuce seedlings were cultivated with these biofertilizers, plant growth parameters, photosynthetic pigments, nitrogen uptake assessed. Soil incubation experiments further examined mineralization rates, while DNA sequencing analyzed shifts in rhizosphere communities. grown biofertilizers exhibited improved parameters compared controls, achieving 31.89% increase shoot length, 27.98% root 47.33% fresh weight. Chlorophyll total chlorophyll levels increased significantly all treatments, highest concentrations observed treatment. studies revealed that DMB DAEMB provided gradual release, rapid supply. Microbial analyses bacterial fungal diversity, abundance nitrogen-fixing nutrient-cycling taxa. Notably, diversity was enriched health reducing pathogenic fungi. These findings highlight biofertilizers' enhance fertility, health, sustainable resource use agriculture.

Effects of microbial organic fertilizers on soil microbial communities and physicochemical properties in tobacco cultivation

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 13

Published: March 26, 2025

Introduction: Tobacco, as an economic crop in our country, not only requires changes cultivation practices but also benefits from reasonable fertilization to enhance yield and quality. Microbial organic fertilizers (MOFs) have received considerable attention recent years; however, the relationship between rhizosphere soil microorganisms of tobacco plants physicochemical properties with MOFs remains poorly understood. Methods: This study established experimental control groups, employing a five-point sampling method collect samples leaves at four different growth stages. High-throughput 16S rRNA gene sequencing was conducted analyze microbial community structure, while physical characteristics were examined. Results Discussion: The results indicated that MOF reduced uptake ammonium nitrogen by stages, promoted dispersion community, significantly altered structure. At phylum level, Actinobacteriota Proteobacteria are first second dominant bacterial phyla community. Significantly, during prosperous stage tobacco, relative abundance (14.90%) group lower than (19.87%), whereas group, (22.99%) higher (22.06%). Furthermore, assessment leaf morphology, yield, quality demonstrated application resulted 21.93% increase 27.38% value per unit area. nicotine content slightly decreased. In summary, this demonstrates can improve communities leaves, providing valuable insights into effects on altering improving

Harnessing plant–microbe interactions: strategies for enhancing resilience and nutrient acquisition for sustainable agriculture

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: April 15, 2025

The rhizosphere, a biologically active zone where plant roots interface with soil, plays crucial role in enhancing health, resilience, and stress tolerance. As key component achieving Sustainable Development Goal 2, the rhizosphere is increasingly recognized for its potential to promote sustainable agricultural productivity. Engineering microbiome emerging as an innovative strategy foster growth, improve adaptation, restore soil health while mitigating detrimental effects of conventional farming practices. This review synthesizes recent advancements omics technologies, sequencing tools, synthetic microbial communities (SynComs), which have provided insights into complex interactions between plants microbes. We examine root exudates, composed organic acids, amino sugars, secondary metabolites, biochemical cues that shape beneficial rhizosphere. further explores how advanced techniques like metagenomics metabolomics are employed elucidate mechanisms by exudates influence health. Tailored SynComs shown promising resilience against both abiotic stresses (e.g., drought salinity) biotic challenges pathogens pests). Integration these microbiomes optimized exudate profiles has been nutrient cycling, suppress diseases, alleviate environmental stresses, thus contributing more By leveraging multi-disciplinary approaches optimizing profiles, ecological engineering plant-microbiome presents pathway boosting crop approach also aids managing soil-borne reducing chemical input dependency, aligning Goals aimed at global food security sustainability. ongoing research offers significant promise ensuring long-term productivity preserving future generations.
