Abstract:
Carbon nanotubes (CNTs) are allotropes of carbon (C) with a round and hollow nanostructure, framed by the movement of hexagonally shaped C molecule planes (graphene sheets) into tubes. There could be both single-walled and multi-walled nanotubes. They are renowned for their extremely high thermal (greater than 3000 W m-1 K -1 ) and electrical conductivities (106 -107 dS m-1 ). The application of CNTs to boost crop productivity is a relatively new field that requires investigation. Due to endo-osmotic root pressure, water-soluble carbon nanotubes in the vascular bundle of plants form a "head-to-tail configuration". In response to CNT treatment, plant water absorption increases considerably. Natural organic matter (NOM) is absorbed by carbon nanotubes, and the isotherm experiment results are consistent with a modified Freundlich isotherm model. At high quantities, carbon nanotubes inhibit the activity of C degrading and phosphorus (P) mineralizing enzymes (500 ppm or beyond that). It is also capable of altering the microbial community structure in certain crop rhizospheres. According to reports, carbon nanotubes have a priming effect on C mineralization in various soils. The mineral nutrient delivery (Calcium, Iron, and Chlorine) to plants is similarly affected by multi-walled CNTs. Carbon nanotubes have been credited with increasing the growth and productivity of various crops, such as tomato (Solanum lycopersicon), gram (Cicer arietinum), and others. But CNTs are not always a win-win strategy, as greater concentrations have a negative impact on soil microbes, notably the fungal community. Despite the potential of CNTs, it is evident that society is currently evaluating potential results.
