To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

There is currently a great deal of information available about the toxic effects oxyfluorfen on soil biochemical activity and microbial biodiversity. However, there no how this herbicide affects plant growth promoting bacteria (PGPB) or their properties, such as biofilm formation, nitrogen fixation, siderophore auxin production, phosphate solubilisation. As in study an agricultural was polluted...

background and aims. increasing the temperature of sodium hypochlorite (naocl) enhances its dissolution and antibacterial properties. however, the high resistance of multi-species biofilms could restrict the effect of the solution regardless of its temperature, enabling the long-term recovery of the surviving bacteria. the aim of this study was to investigate if the increase of temperature of n...

The use of phosphate solubilizing bacteria as inoculants simultaneously increases P uptake by the plant and crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium are among the most powerful phosphate solubilizers. The principal mechanism for mineral phosphate solubilization is the production of organic acids, and acid phosphatases play a major role in the mineralization of org...

Phosphate minerals hydroxylapatite, fl uorapatite and crandallite were identifi ed in nodules within phosphorites from Ervenik, Croatia. The minerals were identifi ed using optical microscopy, XRD, SEM and EDS analyses. The presence of fungi was recognized only in association with phosphate-rich phases. Fungal activity resulted in the dissolution of apatite, producing hollow crystals, particula...

In order to screen the strains with Potassium and phosphorus-releasing bacteria from soil, potassium-dissolving medium was used for preliminary screening, transparent circle method re-screening. The content of soluble potassium determined by sodium tetraphenylborate method, phosphorus anticolorimetric molybdenum antimony. were identified morphological, biochemical molecular biology. results sho...

This is a review of acid aluminum phosphate for the binding and coating of materials. The acid aluminum phosphate in the form of a solution obtained by dissolving aluminum hydroxide in phosphoric acid, with a P/Al molar ratio of 23, is effective for the binding of fibrous or particulate materials. Porous ceramic articles are made using this binder by wet forming, followed by heat treatment. The...

Aims: Soils in Ghana's coastal savanna are typically poor phosphorus (P), which has an impact on crop growth and productivity. The majority of West African phosphate rock formations not reactive; therefore, their direct applications do facilitate easy P availability to crops. Co-composting organic waste with using phosphorus-solubilizing microorganisms is the new paradigm adopted by scientists ...

background and objectives: azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.the aim of this study was to isolate azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic pi compounds. materials and methods: in this study, soil samples collected from a diverse range of slightly alkaline soil type...
