Book Description
In comparison to major nutrients, phosphorus is by far the least mobile and available to plants. Most developing countries economic stability depends on agricultural yield, hence to feed rapidly increasing population excessive use of chemical fertilizers is there. As a solution PSM are employed that renders inorganic phosphorus to be available to plants in soluble form and mineralize organic phosphorus, (eco friendly) limiting the use of fertilizers. The solubilization of phosphatic compounds by naturally abundant PSM is studied under in vitro conditions. We have collected soil samples from different agricultural crops growing near by our campus processed all the samples for microbiological analysis within 24 hours. We have isolated large number of phosphate solublising colonies selected efficient phosphate solubilizers with high solubilization index for futher analysis and scaled down to few good phosphate solubilizers with high phosphatase activity. A nursery experiment was undertaken to evaluate the effectiveness of these strains in improving the growth and phosphorus level in maize seedlings. This review presents utilization of PSM with a view to foster sustainable agriculture.

Book Description
With an ever-increasing human population, the demand placed upon the agriculture sector to supply more food is one of the greatest challenges for the agrarian community. In order to meet this challenge, environmentally unfriendly agroch- icals have played a key role in the green revolution and are even today commonly recommended to circumvent nutrient de?ciencies of the soils. The use of ag- chemicals is, though, a major factor for improvement of plant production; it causes a profound deteriorating effect on soil health (soil fertility) and in turn negatively affects the productivity and sustainability of crops. Concern over disturbance to the microbial diversity and consequently soil fertility (as these microbes are involved in biogeochemical processes), as well as economic constraints, have prompted fun- mental and applied research to look for new agro-biotechnologies that can ensure competitive yields by providing suf?ciently not only essential nutrients to the plants but also help to protect the health of soils by mitigating the toxic effects of certain pollutants. In this regard, the role of naturally abundant yet functionally fully unexplored microorganisms such as biofertilizers assume a special signi?cance in the context of supplementing plant nutrients, cost and environmental impact under both conventional practices and derelict environments. Therefore, current devel- ments in sustainability involve a rational exploitation of soil microbial communities and the use of inexpensive, though less bio-available, sources of plant nutrients, which may be made available to plants by microbially-mediated processes.
Phosphate Solubilizing Microbes

Book Description
Globally, most agronomic soils contain huge reserves of phosphorus, but the fixation and precipitation, cause a major deficiency of Phosphorus in soil, and in turn, hamper the growth of crops seriously. How to improve phosphorus fertilizer efficiency and utilize the potential nutrient in soil has therefore, long been a major concern for field practitioners. This has led to a search for eco-friendly and economically attractive alternative technology for improving crop production in low or even P deficient soils. In this context, natural soil inhabitants endowed with P-solubilizing activity, often termed phosphate-solubilizing microorganisms [PSM], provides a viable substitute to chemical P fertilizers. Inoculation of phosphate-solubilizing microorganisms, like, bacteria and fungi in soil has been shown to immensely affect the growth of plants by making not only P available to plants but also facilitate the growth of plants by other mechanisms leading to higher crop yields.
Potassium Solubilizing Microorganisms for Sustainable Agriculture
Author: Vijay Singh MeenaPublisher: Springer
ISBN: 813222776X
Category : Technology & Engineering
Languages : en
Pages : 338
Book Description
The potassium solubilizing microorganisms (KSMs) are a rhizospheric microorganism which solubilizes the insoluble potassium (K) to soluble forms of K for plant growth and yield. K-solubilization is carried out by a large number of saprophytic bacteria (Bacillus mucilaginosus, B. edaphicus, B. circulans, Acidothiobacillus ferrooxidans, Paenibacillus spp.) and fungal strains (Aspergillus spp. and Aspergillus terreus). Major amounts of K containing minerals (muscovite, orthoclase, biotite, feldspar, illite, mica) are present in the soil as a fixed form which is not directly taken up by the plant. Nowadays most of the farmers use injudicious application of chemical fertilizers for achieving maximum productivity. However, the KSMs are most important microorganisms for solubilizing fixed form of K in soil system. The KSMs are an indigenous rhizospheric microorganism which show effective interaction between soil-plant systems. The main mechanism of KSMs is acidolysis, chelation, exchange reactions, complexolysis and production of organic acid. According to the literature, currently negligible use of potassium fertilizer as chemical form has been recorded in agriculture for enhancing crop yield. Most of the farmers use only nitrogen and phosphorus and not the K fertilizer due to unawareness that the problem of K deficiency occurs in rhizospheric soils. The K fertilizer is also costly as compared to other chemical fertilizers.

Book Description
Phosphate Solubilizing Microorganisms (PSMs) are typical environmental microbes, which can transform insoluble phosphate into plant absorbable forms in soil. The metabolites of organic acid by PSM usually dominate the insoluble phosphate dissolution and phosphorus transformation in soil. The tricarboxylic acid cycle (TCA) is the main metabolic pathway of organic acids secretion by PSM. Genetic, enzyme, and fermentation engineering technology can significantly affect the TCA pathway, changing the type and quantity of organic acid secretion, hence greatly affecting the application of PSM. In the case of fungi, the enhanced oxalic acid secretion is conducive to lead remediation, while food fermentation engineering needs more citric acid. In addition, the above biotechnology also greatly impacts other metabolites of PSMs, such as phosphatases, degrading enzymes and volatile organic compounds, etc. Therefore, promoting the capacity of metabolism via biotechnology is a current challenge for PSM in the pathway of application in food fermentation, environmental remediation, agricultural production, and biocontrol of plant pathogens.
