Effects of Nanomaterials on Crops

It is essential to review the outcome of nanomaterials on crop growth and development, as well as their underlying applications and risks in agriculture. The agricultural department need to seek a more efficient and sustainable production approach with the global population growth and increasing resource pressure. A number of results have demonstrated that nanomaterials have significant advantages in the enhancement of crop stress resistance, promoting growth and yields due to their unique physical and chemical properties. The paper summarizes the impact of nanomaterials on seed germination, vegetative, and reproductive growth by analyzing existing research. It discusses how nanomaterials improve crop adaptability by regulating the antioxidant system, enhancing photosynthesis, and optimizing nutrient absorption. In addition, the review highlights the potential risks associated with nanomaterials in soil ecosystems, food chain transmission, and human health, including possible negative impacts on soil organisms, microbial communities, and food safety. Finally, this review emphasizes the need for the enhancement of long-term ecological security assessments and the development of intelligent delivery systems in future research, which can ensure the safe and efficient application of nano-agricultural technologies.
