Abstract:

The application of plant beneficial microorganisms is widely accepted as an efficient alternative to chemical fertilizers and pesticides. It was shown that annually, mycorrhizal fungi and nitrogen-fixing bacteria are responsible for 5 to 80% of all nitrogen, and up to 75% of P plant acquisition. However, while bacteria are the most studied soil microorganisms and most frequently reported in the scientific literature, the role of fungi is relatively understudied, although they are the primary organic matter decomposers and govern soil carbon and other elements, including P-cycling.

Abstract:

ABSTRACTDuring fungal rock phosphate (RP) solubilization, a significant quantity of fluoride (F−) is released together with phosphorus (P), strongly inhibiting the process. In the present study, the effect of two F−adsorbents [activated alumina (Al2O3) and biochar] on RP solubilization byAspergillus nigerwas examined. Al2O3adsorbed part of the F−released but also adsorbed soluble P, which makes it inappropriate for microbial RP solubilization systems. In contrast, biochar adsorbed only F−while enhancing phosphate solubilization 3-fold, leading to the accumulation of up to 160 mg of P per liter

Abstract:

Phosphorus (P) is one of the essential nutrients that functions is metabolism in plant. Based on these functions, it indicates that nutrient P has an important role for plant growth and production. However, its availability in soil is very low, which is less than 0.01% of the total P. Therefore, the availability of P nutrients in the soil needs to be increased by increasing the activity of soil microorganisms through the use of phosphate solubilization bacteria. This research is aimed to show the changes in the physiological characteristics of tomato plants through the application of phosphate

Abstract:

Phosphorus-rich biochar derived from sewage sludge (SS) could be a sustainable alternative P source for agriculture. However, most of biochar P is not readily available to plants. We evaluated the potential of P release from SS biochar into soil solution by Aspergillus niger. Additionally, we assessed the effect of SS biochar on the solubilization of phosphate minerals by the fungus. An incubation study was performed for 7 days in shaken flasks containing culture medium supplemented, or not, with a P-fixing soil. Biochar showed a dual role in phosphate solubilization by A. niger: (i) improved

Abstract:

Salinity is one of the most severe environmental constraints that limit agricultural productivity. Exploiting microorganisms with nutrient solubilizing and plant growth−promoting potential is an affordable natural approach to salinity alleviation. The current study was designed to isolate and screen salt−tolerant P−solubilizing fungi from salt−affected soils and optimize their growth parameters for future development as bioinoculants. Fifteen salt−tolerant P−solubilizing fungal isolates were evaluated. Fungi grown in potato dextrose medium (PDM) produced more biomass than those grown in Pikovs

Abstract:

The improvement of phosphorus (P) use efficiency (PUE) is a critical problem in crop production because of phosphorus’ scarcity. Especially in strongly weathered soil with a high P fixation capacity, a low PUE generally limits plant growth. Here, in a 70-day pigeon pea cultivation pot experiment using Ultisols, we evaluated the effects of Rhizobium inoculation (−I/+I) on the plant growth, rhizosphere, bulk soil P dynamics, and plant root P acquisition characteristics, with or without P fertilization (0P: no P application; 50SSP:50 kg P ha−1 with single superphosphate).

Abstract:

This study aims to investigate solubilization of elements (P, N, K, Ca and Mg) during anaerobic digestion (AD) of solid agriculture waste. It is important to maintain particularly phosphorous in the aqueous phase to be able to subsequently recover it in a concentrated form via crystallization. Batch AD was carried out at a mesophilic condition (37 °C) and pH 7.0 ± 0.2 on a variety of piggery and poultry solid waste streams. Less than 10% of the total P, Ca and Mg was in soluble form in the digestate. Most of the N and K remained soluble in the digestate. A bioavailability test (citric acid ext

Abstract:

Pseudomonas extremaustralis was first isolated from Antarctica and gained interest for its ability to thrive in extreme environmental conditions and degrade recalcitrant compounds. Some strains have been identified as phosphobacteria, which play a significant role in phosphorus (P) cycling by solubilizing or mineralizing insoluble phosphate forms for plant uptake. However, there is limited knowledge about the genomic mechanisms involved in P-cycling in the species P. extremaustralis. In this study, we aimed to evaluate the genomic potential of P. extremautralis as a phosphobacteria species by

For this, phosphorus-solubilizing fungal strains were selected for evaluation of their solubilization potential and phosphatase activity.

As a result of the analysis of semi-quantitative solubilization of Si, P and K using Alexandrov’s agarized medium, 15 strains were tested. Of the studied strains, only three strains of the genus Bacillus spp. caused simultaneous extraction of Si, P and K. The obtained primary data can be used in biotechnological production of bacterial fertilizers

Abstract:

Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH for its absorption by plants is about 6.5, but in alkaline and acidic soils, most of the consumed P forms an insoluble complex with calcium, iron, and aluminum elements and its availability for absorption by the plant decreases. The supply of P needed by plants is mainly achieved through chemical fertilizers; however, in addition to the high price of these fertilizers, in the long run, their destructive effects will affect the soil and the environment.

One of the major essential macronutrient for plant is phosphorous and is applied to soil in the form of chemical phosphatic fertilizers which is immobilized rapidly and becomes unavailable to plants. Microorganisms are involved in the transformation of soil P and is thus an integral part of the soil P cycle. In particular, soil microorganisms are effective in releasing P from inorganic and organic pools of total soil P through solubilization and mineralization. P-solubilization ability of the microorganisms is considered to be one of the most important properties. The adverse impact of chemica
