“…Some PGPMs have been reported to manufacture organic compounds and release them into the soil, hence alleviating the inorganic phosphate solubilization (Pi) and K (De Palma et al, 2022). Moreover, recent research has displayed how they can produce acid phosphatases and phytases, thereby increasing the mineralization of P (Saranya et al, 2022;Zhao et al, 2022). In addition, hydrogen cyanide (HCN)-stimulating bacteria partake in accelerating the accessibility of P and the utilization of heavy metals with advantageous results for PGPRs and crop plants (Elnahal et al, 2022).…”

To improve agricultural sustainability, an agriculturally productive system is required to maintain soil fertility and reduce the loss of soil biodiversity. One of the modern technologies employs microbial biostimulants that create abundant agricultural yield with high nutritional values, controlling disadvantages obtained from environmental changes. This review aimed to provide knowledge on the effects of biostimulants on microbial communities’ potential to promote agricultural production. Plant biostimulants are novel materials applied in the farming sector nowadays to improve crop yield and commonly occur in plant seeds and as an alternative to chemical derivative application on crop plants. Microbial biostimulants function as biological inputs to increase crop production and reduce the decomposition of soil. In conclusion, the application of biostimulants necessitates the accomplishment of an absolute choice of beneficial microbes as well as the potential to combat problems that will be encountered later in the agricultural sector.

“…Moreover, plant-beneficial bacteria are capable of solubilizing insoluble forms of phosphorus (P) in soil, making it available for plant uptake. These bacteria play an important role in the biogeochemical cycle of P, which is a vital nutrient for plant growth [50]. They can solubilize the insoluble form of phosphorus by secreting organic acids, phosphatases, and other enzymes that break down the complex phosphorus compounds into simpler forms, such as soluble orthophosphate, which plants can readily absorb.…”

Plant growth and nutrition are adversely affected by various factors such as water stress, high temperature, and plant pathogens. Plant-associated microbes play a vital role in the growth and development of their hosts under biotic and abiotic stresses. The use of a rhizosphere microbiome for plant growth stimulation and the biological control of fungal disease can lead to improved crop productivity. Mechanisms used by plant-growth-promoting rhizobacteria (PGPR) to protect plants from soilborne pathogens include antibiosis, the production of lytic enzymes, indole-3 acetic acid production, decreasing ethylene levels by secreting 1-aminocyclopropane-1-carboxylate deaminase, competition for nutrients and niches, parasitism and induced systemic resistance. In this review, we emphasize the biological control of plant pathogens by root-associated microbes and discuss traits involved in pathogen reduction. Future research should focus on the effect of root exudation on plant–pathogen interactions under various abiotic factors. Moreover, the development of microbial fungicides with longer shelf lives will help farmers to opt for organic agriculture, reducing the use of chemical fertilizers. This trend is expected to drive the adoption of biological control methods in agriculture. The future prospects for the biological control of plant diseases are bright and are expected to play an increasingly important role in sustainable agriculture.
