Carbon nanodots (CNDs) have emerged as promising nanomaterials with potential applications in agriculture, particularly as fertilizers and nutrient carriers. Due to their unique properties, such as high surface area, biocompatibility, porosity, and the ability to functionalize with various chemical groups, CNDs can enhance the efficiency of nutrient delivery to plants. This capability allows for the controlled release of essential macronutrients and micronutrients, improving plant growth and productivity. Carbon nanodots can also facilitate the uptake of nutrients by plant roots, increasing nutrient availability and reducing the loss of fertilizers to the environment. Furthermore, their ability to protect nutrients from degradation or leaching offers a more sustainable and efficient approach to fertilization. In this context, the potential of CNDs as advanced fertilizers and nutrient carriers, highlighting their benefits, such as seed germination promotion, enhancement in photosynthesis of crop plants, improved water retention and nutrient utilization capacities, enhanced plant growth and crop quality, improved abiotic stress tolerance and disease resistance, and reduced environmental impact, has been focused on. Besides this, the environmental impact of CNDs has also been discussed. However, challenges related to large-scale production, optimal application methods, and long-term environmental safety remain, requiring further research for practical adoption in agriculture.
