The book describes how nanobiostimulants, which are nanoscale materials that can enhance plant growth and productivity, have the potential to revolutionize sustainable agriculture practices. The book covers a wide range of topics, including the properties and functions of nanobiostimulants, the mechanisms behind their effects on plant growth, and the potential risks associated with their use. It also discusses how nanobiostimulants can be used to improve soil health and nutrient uptake, enhance plant resistance to environmental stresses, and increase crop yields. Overall, the book provides a comprehensive overview of the emerging field of nanobiostimulants and its potential applications in sustainable agriculture. It will be of interest to researchers, students, and professionals in the fields of agriculture, nanotechnology, and environmental science.
