A study was conducted to determine the total microbial population, the occurrence of growth promoting bacteria and their beneficial traits in acid sulfate soils. The mechanisms by which the bacteria enhance rice seedlings grown under high Al and low pH stress were investigated. Soils and rice root samples were randomly collected from four sites in the study area (Kelantan, Malaysia). The topsoi...

Phosphorus (P) is a critical nutrient that plays an essential role in improving soil fertility for optimum plant growth and productivity. It one of the most deficient macro-nutrients agricultural soils after nitrogen considered inadequate production. To P availability soils, farmers are applying huge amounts synthetic fertilizers adversely affect wider environment, groundwater, microbial popula...

To reduce requirements for conventional chemical fertilizer and alleviate salinity stress in soils, a glasshouse experiment was conducted to assess the effects of enriched biochar on phosphatase activity, microbial respiration wheat yield non-saline saline soils from Lake Urmia basin (electrical conductivities 2 dS.m−1 15 dS.m−1, respectively). Nine treatments were tested: control, 1:1 mixture ...

Abstract Most soils contain Phosphorus (P) in insoluble compounds as organic and inorganic forms which is unavailable to plants. Furthermore, phosphate solubilizing bacteria (PSB) play an important role converting P a bioavailable form through mineralizing or P. Therefore, this study aims determine the ability of isolate bacterium (PSB), Stenotrophomonas maltophilia solubilize The was isolated ...

The present investigation entitled “The effect of integrated nutrient management on various growth parameters cluster bean (Cyamopsis tetragonoloba L.)” was carried out at Horticultural Research Centre Sardar Vallabhbhai Patel University Agriculture & Technology, Meerut – 250110 during 2022-23. In this study (INM), farmyard manure (FYM), vermicompost and phosphate solubilizing bacteria (PSB...

It has been reported that phosphate solubilizing bacteria (PSB) are the most promising bacteria among the plant growth promoting rhizobacteria (PGPR); which may be used as biofertilizers for plant growth and nutrient use efficiency. Moreover, these soil micro-organisms play a significant role in regulating the dynamics of organic matter decomposition and the availability of plant nutrients such...

Plant growth promoting rhizobacteria (PGPR) mediate the soil processes such as decomposition, nutrient mobilization, mineralization, solubilization, nitrogen fixation and growth hormone production. Microorganisms having the phosphate solubilizing capacity can convert the insoluble phosphates into soluble forms through the production of organic acids. Inoculation of seed with P-solubilizing micr...

Phosphorus (P) availability in calcareous forest soils is commonly low compared to siliceous soils. The main reason for this that phosphate ions tend precipitate with calcium (Ca). Weathering of rocks and the potential microorganisms dissolve parent material not fully understood. Therefore, we examined microbial carbonate dissolution abundance phosphorus-solubilizing bacteria temperate contrast...

Microorganisms with the ability to release nutrients to the soil from insoluble sources may be useful for plant cultivation. We evaluated the growth-promoting effect on Jatropha curcas L. of phosphate-solubilizing bacteria (PSB) and the native microbiota in soil with or without rock dust. J. curcas L. is important for biodiesel production. The experiments were performed in a greenhouse under a ...
