Rhizosphere is a site of high microbial diversity that makes soil more physiologically active. High diversity of bacteria in the rhizosphere depends on physicochemical composition of soil, its pH, partial pressure of oxygen (pO2) and water potential. The continuous increase of population and availability of low-production land causes high demand of crop production with a significant decrease of synthetic chemical fertilizers and pesticide use which is a huge challenge nowadays. Plant growth-promoting rhizobacteria are free-living, soilborne rhizobacteria that play a significant role in the sustainable agriculture. Soil diversity of microbes shows key role in maintaining soil fertility, functions and crop productivity. The use of metal nanoparticles to increase the soil microbial diversity has been reported recently. Although metal nanoparticle could meaningfully produce ecotoxicity and kill phytostimulatory soil bacteria, so engineered nanoparticles (ENPs) using gold, silver and aluminium should be added to test as a possible ecofriendly agent, and others on the PGPR.
