Comparison of some exogeneous solubillizing phosphate bacteria on Andisol as Indonesia dominant native tea soil

Abstract

Tea was planting an upland area with Andisol as the dominant soil ordo. Andisol has a special characteristic i.e. low soil pH and it has more mineral that causing low of soil phos-phate soluble, especially for tea plants, there-fore the rule of solubilizing phosphate bacteria will be needed. Laboratory scale experiments were conducted to study the capability activities of some solubilizing phosphate bacterias name-ly Pseudomonas cepaceae, P. malei, Bacillus mycoides, and B. subtilis. The experiment was arranged in Completely Randomized Design with six treatments and four replications. The result on statistical analysis shown that there were no significant differences in increasing of the soil phosphate soluble. Nevertheless, the treatment D (Bacillus mycoides) produced the highest soil phosphate soluble. The capability of bacteria to increase soil phosphate soluble was depended on its habitat, especially soil pH. Even all of the isolates were the superior solubilizing phosphate bacterias in agricultural food plants with neutral soil pH, but they have not significantly different on Andisol. There-fore, the using of indigenous isolates on tea plant areas was suggested.

The role of rhizosphere microbes as phosphate solubilizing bio fertilizers in shallot: a review

“…The use of phosphate-dissolving microbes is an approach with the principles of sustainability and environmental friendly in managing P deficiency in agricultural soil [1,67]. The fundamental process for dissolving phosphate minerals in soil is the creation of phosphatase enzymes and organic acids [68]. Phosphate-solubilizing bacteria isolated from coastal soils in Indonesia include Acinetobacter, Aeromonas, Arthrobacter, Bacillus, Citrobacter, Enterobacter, Halomonas, Microbacterium, Ochrobactrum, Pantoea, Providencia, Pseudomonas, Sinomonas, and Streptomyces [69].…”

“…Based on Istina et al [92] the indigenous phosphate solubilizing microbe Burkholderia gladiola and Penicillium aculeatum can increase the soils P nutrient content. The other phosphate solubilizing bacteria Bacillus sp, can dissolve phosphate qualitatively [93], which can escalate the nitrogen and phosphate availability of soils, are B. Subtilis, B. amyloliquefaciens, B. pumilus [94] and B. mycoides [68]. Other bacteria in increasing N and P uptake in maize are Bacillus amyloliquefiniens [95].…”

Enhancing Melon Growth and Nutrient Uptake with Plant-Growth-Promoting Microorganisms from Cucumis melo

“…PSM has been widely accepted as an environmentally friendly and easy-to-obtain P fertilizer for increasing soil orthophosphate concentrations and the geochemical P cycle since the early 20th century [41]. PSM produces organic acids and enzymes such as phosphatase and pyrophosphatase which can dissolve P to become available [64,65]. PSM has many roles for plants, including growth boosters [39], biocontrol and bioremediation activities [40], and increasing plant growth and fruit yields [41].…”

Isolation and Characterization of Phosphate Solubilizing Bacteria from Upland Rice Cultivation Areas in Bangka Regency

“…Numerous studies have been undertaken to investigate the efficacy of bacterial inoculation in enhancing P availability. Setiawati and Pranoto (2015) highlighted that the capacity of these bacteria to solubilize phosphate faced limitations when introduced into different environments. Furthermore, Awais et al (2017) emphasized the variability in population sizes of PSB across different soil types.…”
