Time-Dependent Dissolution of Potassium from K-Bearing Mineral Residues in Organic Acids

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Март 6, 2025

Background and Aims: Potassium (K)- bearing minerals are vital for soil fertility act as slow-release reservoirs crop productivity. Organic acids, such oxalic citric enhance K dissolution. Methods Time-dependent experiments measured dissolution from in acids. Mehlich-1 extraction atomic absorption spectrophotometry quantified release over intervals under controlled conditions. Results Oxalic acid enhanced by 25% more than acid. For biotite-mica, increasing concentration 0.5 to 5.0 mmol L⁻¹ raised 800 1600 mg kg⁻¹. During a further increase 10 L⁻¹, slightly improved was recorded. Percentage varied mineral, muscovite-mica, K-feldspar recorded 5–11%, 3–7%, 2–6% respectively. Citric caused significant between 1.0 with increases up L⁻¹. Above 5 muscovite-mica dissolved biotite-mica K-feldspar, showing higher percentages of 3.1–7.5% that 2.4–6.2%. Conclusion acids via chelation, destabilization mineral surfaces, solubility increases. acid’s superior performance highlights its role improving fertility. Also, outperformed dissolving minerals, underscoring the importance targeted nutrient management strategies.

Screening and Identification of Cold-Tolerant Phosphorus and Potassium Solubilizing Bacteria and Their Growth-Promoting Effects on Soybean in Cold Regions

Agronomy, Год журнала: 2024, Номер 15(1), С. 40 - 40

Опубликована: Дек. 27, 2024

In this study, we collected soybean inter-root soil (clay soil) from the cold region of Heilongjiang Province, China, screening for cold-tolerant phosphorus- and potassium-solubilizing bacteria by gradient-cooling-directed design mixed bacterial agents. This study screened phosphorus-solubilizing constructed We analyzed strain’s phosphorus/potassium solubilizing capacity, as well its organic acid secretion ability, to reveal mechanism detoxification phosphorus potassium. Clay Heilongjiang, was potting trials. The pot experiment used investigate growth-promoting effects strains applied soybeans analyze changes in activity on growth. A dominant strain P-5 (Pantoea ananatis) screened, amount 34.94 mg/L with a PSI (Phosphorus Solubilization Index) 1.80 7 days incubation at 15 °C. OD600 value (optical density 600 nm) 10th day 0.61. bacteria, K-1 (Rahnella aquatilis), solubilized 23.02 potassium under same culture conditions, KSI (Potassium Solubilization) 1.51 an 0.59 10. agents H-5 (25% 75% K-1), designed above two, detoxified 62.58 37.59 conditions. It shown that P-2 secretes gluconic lactic degrade insoluble low temperatures citric showed application (PSB), (KSB), (MSB) alone could enhance relative abundance Pseudomonas, Rhizobium, other genera planting soil, compared control treatment without (BLK). Indirectly, they can accumulation various organs soybean, promote development leaves stems, achieve effect promoting production increasing income. has important theoretical replacement chemical fertilizer microbial it practical strategic significance promotion income green safety China’s main grain-producing areas.
