Phosphorus is a macronutrient crucially important for plant growth and development; its limited amount in soil water poses bewildering concerns amongst agronomists. Externally applied phosphorus fertilizers can fulfil crops’ needs throughout essential stages; however, the overapplication of leads to diminished acquisition efficiency (PAE), disrupts delicate balance nutrients water, deficiencies other elements, significant environmental risks, accelerates loss mineral supplies. Moreover, much may become fixed as insoluble phosphates by combining with calcium, iron, aluminum, manganese, etc., present soil, making it unavailable plants. Phosphate solubilizing bacteria (PSB) render phosphate accessible plants solubilization mineralization, hence enhancing crop yields while ensuring sustainability. Earthworms are vital invertebrates that interact continuously microorganisms play an role maintaining fertility. The study aims screen identify potential from intestinal tract earthworm Aporrectodea rosea. experimental results indicate strain PSEG-1 was effective solubilization, index 1.6 Pikovskaya (PVK)’s medium. produced organic acid National Botanical Research Institute (NBRIP)’s Phenotypic genotypic studies isolate showed belongs Klebsiella variicola. Our suggest vermi-bacterial variicola possesses intrinsic abilities solubilize phosphate, which could be exploited formulating microbial biofertilizers enhance production.

Phosphorus Release from Nano-Hydroxyapatite Derived from Biowastes in the Presence of Phosphate-Solubilizing Bacteria: A Soil Column Experiment

Journal of Agricultural and Food Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 7, 2025

Phosphorus applications in agriculture can lead to significant environmental impacts, necessitating a revolution current agricultural practices. This study explores the potential of hydroxyapatite nanoparticles (nHAPs) synthesized from poultry bones as P fertilizers. nHAPs were produced at 300 °C (nHAP300) and 700 (nHAP700), their effectiveness was evaluated. An vitro solubilization test with Pseudomonas alloputida evaluated bacterium's ability solubilize nanoparticles, assessing dissolved organic acids produced. Additionally, soil leaching measured losses bioavailable compared conventional fertilizer, triple superphosphate (TSP). nHAP300 displayed heterogeneous sizes, while nHAP700 approximately 100 nm size, content 8.8% 19.4%, respectively. successfully solubilized both types demonstrating higher solubility than nHAP300. The TSP treatment resulted (6.35 mg) nHAP treatments (nHAP300 0.32 mg; 0.28 mg), indicating for recycling waste. Our findings indicate that are more efficient release but less prone Utilizing these enables phosphorus recovery waste holds sustainable applications.

Unveiling the roles, mechanisms and prospects of soil microbial communities in sustainable agriculture

Discover Soil., Journal Year: 2025, Volume and Issue: 2(1)

Published: Feb. 17, 2025

Abstract Soil hosts diverse microbial communities including bacteria, fungi, archaea, protozoans and nematodes among others, which are fundamental to sustainable agriculture drive essential processes that underpin soil fertility, plant health, ecosystem resilience. They promote growth through mechanisms like nitrogen fixation, phosphorus solubilization, production of growth-promoting substances, enhancement nutrient uptake, improvement structure detoxification harmful substances. Recently, there has been increasing interest in utilizing microorganisms improve health boost efficiency, despite limited understanding diversity, microbe-plant interactions, translating laboratory findings field conditions. This is driven by the urgent need feed growing global population, placing pressure on arable land produce high-quality yields. Conventionally, synthetic fertilizers have extensively used provide nutrients, growth, increase crop productivity. Although revolutionized since green revolution, their overuse significantly harmed reduced review synthesizes current knowledge microbes influence agricultural practices, with a focus cycling plant–microbe interactions. We discuss functions important groups, such as nitrogen-fixing phosphorus-solubilizing bacteria (PSB), fungi. Furthermore, we factors highlight gaps future research maximize potential use agriculture. Understanding significance key increases harnessing vital contributors

Effect of Inoculation with Rhizosphere Phosphate-Solubilizing Bacteria on the Growth and Physiological Characteristics of Parashorea chinensis

Forests, Journal Year: 2024, Volume and Issue: 15(11), P. 1932 - 1932

Published: Nov. 1, 2024

Given the challenges of slow growth and low survival rates in early stages Parashorea chinensis cultivation, identifying sustainable methods to enhance seedling performance is critical for successful reforestation conservation efforts. This study aimed address these by investigating growth-promoting effects phosphate-solubilizing bacteria (PSB). One-year-old seedlings P. chinesis were inoculated with PSB strains isolated from rhizosphere soil H. Wang plantations Y3, W5, H8, a mixed strain (Mix), as control (CK). The inoculation on growth, photosynthetic physiology, plant nutrient status, physiological indicators comprehensively evaluated. Results showed that increased height basal diameter chinensis, an increase 1.56 cm 0.53 mm compared CK, respectively, though differences not significant. Mix treatment significantly improved photosynthesis, increases net rate (106.3%), transpiration (93.89%), intercellular CO2 concentration (75.51%) CK. Nutrient levels including total nitrogen, phosphorus, potassium 15.98%, 25.54%, 32.12%, treatments Moreover, stress resistance also improved, higher proline content, soluble sugar, protein levels. Antioxidant enzyme activities (SOD, CAT, POD) 9.83%, 23.66%, 292.32%, while MDA content was reduced 69.01%. acid phosphatase activity 111.88%. In conclusion, inoculation, particularly strain, promoted uptake efficiency seedlings, offering promising biotechnological solution improving performance.
