“…Lower concentrations of carbon dots may have a stimulating effect on the growth of soil microorganisms. 54 In contrast, bacterial biomass in the soil increased by four orders of magnitude with the application of 1.5% N,P-CDs. The results showed that N-CDs and N,P-CDs exhibited low biotoxicity under the experimental conditions.…”

“…For root application, most studies have adopted a hydroponic growth system since this allows for easy root separation and precise control of nutrient availability 64 providing a platform to develop a fundamental understanding of C‐dot‐plant interactions. In contrast, C‐dots root application on plants grown in soil can be extraordinarily complex as they have recently been found to influence soil chemistry and the microbial communities 65,66 . These publications may have just scratched the surface on the interactions of C‐dots and soil.…”

The productivity of global crop production is under threat caused by various biotic and abiotic adverse conditions, such as plant diseases and pests, which are responsible for 20%–40% of global crop losses estimated at a value of USD 220 billion, and can be further exacerbated by climate change. Agricultural industries are calling for game‐changer technologies to enable productive and sustainable farming. Carbon dots (C‐dots) are carbon‐based nanoparticles, smaller than 50 nm, exhibiting unique opto‐electro‐properties. They have been shown to have positive impact on managing diverse biotic and abiotic stresses faced by the crops. Owing to their versatile carbon chemistry, the surface functionalities of C‐dots can be readily tuned to regulate plant physiological processes. This review is focussed on establishing the correlations between the physiochemical properties of C‐dots and their impacts on plants growth and health. The summary of the literature demonstrates that C‐dots hold great promise in improving plant tolerance to heat, drought, toxic chemicals, and invading pathogens.image

“…The significant and direct impact of pH on bacterial community composition may be due to the small optimal growth pH range of bacteria, while the community composition of fungi is less affected by pH, which may be due to the large optimal growth pH range. [104] The global saline and sodic soil are about 11.737 Mkm 2 . [105] Salinization can lead to the change of soil physical shapes such as soil structure viscosity, poor aeration, high bulk density, slow nutrient release, low permeability coefficient and strong capillarity, [106] which will harm the growth and productivity of most crops.…”

Soil microorganisms play a crucial role in maintaining soil ecosystem health. Their metabolic processes are directly impacted by various environmental stresses caused by the increasing release of chemical pollutants and changes in the physical environment due to rapid societal development. This paper aimed to investigate the mechanisms underlying the changes in soil microbial stress responses under various external environmental stresses. The impact of pollutants on soil ecological structure was analyzed by summarizing the stress response patterns of soil microorganisms to inorganic pollutants, organic pollutants, and extreme physical environmental factors. Additionally, the migration and transformation behaviors of various complex pollutants, facilitated by the involvement of soil microorganisms, were investigated. Moreover, a novel approach was proposed for pollutant control, suggesting that manipulating the external physical field of a certain intensity could guide microbial communities and their functions towards controllable evolution within the soil environment. Therefore, this paper was essential for exploring the diversity of soil microbial stress responses, strategically regulating contaminant transport, mitigating risks associated with soil complexity, and ultimately reshaping soil ecological functions.
