Nanocellulose, a promising green material derived from various bio-sources, has potentiality on and off-site in the agricultural sector. Due to its special qualities, which include high strength, hydrophilicity, and biocompatibility, it is a material that may be used in a variety of industries, especially agriculture. This review explores in this article production processes, post-processing procedures, and uses of nanocellulose in soil fertility increment and sustainable agriculture. A variety of plant materials, agricultural waste, and even microbes can be used to isolate nanocellulose. Nanocellulose is produced using both top-down and bottom-up methods, each of which has benefits and limitations of its own. It can be applied as nano-biofertilizer in agriculture to enhance beneficial microbial activity, increase nutrient availability, and improve soil health. Moreover, nanocellulose can be used in fertilizer and pesticide formulations with controlled releases to increase efficacy and lessen environmental effects. Innovative approaches to sustainable agriculture are provided by nanocellulose technologies, which also support the UN's Sustainable Development Goals (SDGs), especially those pertaining to eradicating hunger and encouraging responsible consumption. Nanocellulose promotes climate action and ecosystem preservation by increasing resource efficiency and decreasing dependency on hazardous chemicals, ultimately leading to the development of a circular bioeconomy. Nonetheless, there are still issues with the high cost of production and the energy-intensive isolation procedures. Despite its various potentialities, challenges such as high production costs, environmental concerns, and regulatory issues must be addressed for nanocellulose to be widely adopted and effectively integrated into farming practices.
