Book excerpt: Nano-Fertilizer Synthesis and Types?discusses the production of a variety of nano-fertilizers, including biological, chemical, and mechanical types. Nano-fertilizers aid in nutrition control by increasing nutrient consumption efficiency as nutrients are bonded to nano-dimensional adsorbents, which in turn release nutrients considerably more slowly than traditional fertilizers. As the nano-fertilizer sector advances, one approach is to concentrate on macro elements (N, P, K), as switching to nano-fertilizers may result in significant environmental benefits by replacing the majority of these nutrients. Furthermore, the biosynthesis of nanomaterials employing bacteria, algae, yeast, fungus, actinomycetes, and plants has opened up a new field of study for the creation of inorganic nanoparticles as environmentally benign fertilizers. Because of the several-fold increase in the surface-to-volume ratio of nano-forms of nutrients, and their appropriateness for foliar application, where environmental losses are further decreased, nano-fertilizers may achieve higher efficiency. However, before nano-fertilizers are manufactured and commercialized, further research should be conducted to assess their impact for both humans and the environment. While there are some nano-fertilizer products available, the nano-fertilizer production industry still requires additional public and private sector support and development. Nano-Fertilizers Synthesis and Types presents the latest information, highlights the benefits and impacts of each, and provides a single-volume resource to help effectively and efficiently identify options based on use-case. Exploring the topic from the various mechanistic types to the relevant regulatory, safety, and economic aspects, this volume will be appropriate for those working with and researching new nano-fertilizers. - Guides in the identification of appropriate nano-fertilizer options based on use-case - Addresses both target plant and environmental considerations - Includes economic and regulatory insights
