This book covers the challenges and applications of nanotechnology for managing agroecosystems from maintaining seed quality and ends with food packaging and processing. It covers the use of nanocomposites to manage seed germination, nutrition, biotic and abiotic stresses, and the productivity of crops and the use of nanosensors in detecting pests, pathogens, and pollutants and forecasting soil and crop health. In addition, it also focuses on the risk assessment and regulatory policies of nanoparticles to explore the potential of smart delivery systems in agroecosystems. The book is helpful for students, researchers, growers, policymakers, in the field of nanotechnology in agriculture, sustainable agriculture, soil science, and environmental science.
