To overcome the problems associated with insufficient available phosphorus in ginseng-growing soil, non-targeted metabolomics and high-throughput sequencing were adopted this study to reveal intracellular metabolites of Pseudomonas P1 their effects on soil bacterial community structure after inoculation. The results showed that although colony number was 4.68×107 cfu/mL 32 h cultivation, stabilized at 24 h. Furthermore, 351 differential (162 189 positive negative ion models, respectively) screened from eight cultivation groups. Venn diagrams revealed more common model (45 metabolites) than (17 metabolites). Organic acids derivatives, 23.53% 15.56% positive- negative-ion respectively, may be dominant involved phosphate dissolution. Although inoculation had little effect diversity, significant changes phyla composition identified between P10 CK. Specifically, relative abundance Pseudomonadales higher CK (P < 0.05). Canonical discriminant analyses correlation analysis shifts closely related physicochemical factors, such as phosphate, total potassium, NH4+-N, NO3--N, pH. Our suggest contain several organic acids, which reduce pH inoculation, affect supply change microbial direction cluster evolution.

The use of agricultural chemicals has adversely affected soil health and the environment. Organic farming practices, particularly vermicompost (VC), are gaining attention for their potential to improve fertility crop productivity. This study investigated VC rate applications on lettuce growth, yield, fertility, nutrient dynamics, enzyme activity, biological parameters, biochemical aspects under greenhouse conditions in Samsun, Turkey during 2022–2023. Experimentally, was applied at rates V1: 1%, V2: 2%, V3: 4% w/w, with a control group without application, V0: 0% w/w. Batavia lettuce, which is sensitive environmental deficiency, subjected these treatments randomized complete block design, replicated thrice. Results showed consistent improvements plant dry weight across all treatments, 2% application (V2) yielding highest increase yield (56.43%). Soil pH varied V1 being slightly alkaline V3 showing high electrical conductivity increased nitrogen content. Phosphorus content while potassium varied, having values. activities concentrations, urease activity. Pearson correlations confirmed positive associations growth parameters enzymatic These findings highlight as sustainable solution production improvement.

A Comprehensive Approach Combining Short-Chain Polyphosphate and Bacterial Biostimulants for Effective Nutrient Solubilization and Enhanced Wheat Growth

Microorganisms, Год журнала: 2024, Номер 12(7), С. 1423 - 1423

Phosphorus constitutes a crucial macronutrient for crop growth, yet its availability often limits food production. Efficient phosphorus management is enhancing yields and ensuring security. This study aimed to enhance the efficiency of short-chain polyphosphate (PolyP) fertilizer by integrating it with plant growth-promoting bacteria (PGPB) improve nutrient solubilization wheat growth. Specifically, investigated effects various bacterial strains on germination growth when used in conjunction PolyP. To achieve this, greenhouse experiment was conducted which rhizosphere amended PolyP fertilizer. Based morphological aspect, eight bacteria, designated P1 P8, were isolated further characterized. Plant traits observed all strains, as they presented ability produce Indole Acetic Acid (IAA) significant amounts ranging from 7.5 ± 0.3 µg/mL 44.1 2 µg/mL, expressed

Biodegradable Polymers for Plant Nutrient Delivery and Recovery

Macromolecular Bioscience, Год журнала: 2025, Номер unknown

Опубликована: Март 25, 2025

The current use of fertilizers is inefficient and not sustainable. majority the fertilizer applied does reach targeted crop but lost in water bodies into atmosphere, with harmful impact on environment. To enhance efficiency sustainability agricultural practices, it essential to address two complementary challenges. First, nutrient delivery methods must be refined maximize plant uptake. Second, recovery nutrients from wastewater other waste streams should improved recycling nitrogen phosphorous reduce environmental pollution. Biodegradable polymers hold great promise for development technological solutions toward more sustainable practices. This review covers application biodegradable both aspects cycle: plants through slow- controlled-release fertilizers, using membrane separation, adsorbent composites, coagulants/flocculants. most promising materials are highlighted approaches, identifying research gaps discussing potential future directions this highly significant field.
