摘要

The ecosystem emerges around the plant roots is Rhizosphere which vary in mass and extension rely merely on both plant root exudation and soil conditions. Soil is the viable portion of lithosphere, embraces a massive range of biological and physicochemical elements and is essential to anchor the plant roots and takes major part in plant growth and well-being. Conversion of forest soils from natural ecosystems to agricultural land has significantly impacted soil health and biodiversity specifically affecting the Rhizomicrobiome community. This chapter focuses on understanding their behavior which is crucial to comprehend their recovery patterns after extreme disturbances. Efforts to maximize the crop yields through intensive agricultural practices such as tillage, monoculture, fertilizers and pesticides applications have contributed to impaired ecosystem function and worsening of soil health. Moreover, this chapter illuminate on a newly fit-recognized stressors—microplastics (MP), which have been detected in soils, soil-dwelling organisms and in proximity to plants. This presence can disrupt soil chemistry, impede plant growth and have cascading effects on the survival and fitness of organisms across the food chain. In addition, the new green technology approach aims to minimize chemical inputs, enhance soil fertility and promote plant health through innovative methods; one such strategy involves the application of plant growth-promoting bacteria (PGPB). While PGPB show promise, they also raise concerns about the potential transfer of antibiotic resistance genes to native soil microbes through horizontal gene transfer, which is posing unforeseen consequences for indigenous microbial communities and ecosystem resilience. Looking ahead, there is a need for intensive research aimed at detecting emerging threats and advancing restorative measures. These efforts will focus on reforming practices that compromise natural processes for short-sighted benefits, instead promoting a harmonious coexistence with the environment.
