Outlooks of Nanotechnology in Organic Farming Management

Abstract

Technological advances are getting monitored with time, and science suggests nanotechnology as the emerging future. This even holds correct with human food consumption for health benefits, where organic farming is a better solution for the rising population and is even supported by major countries instead of using chemical fertilisers and pesticides. Nanotechnology provides a platform where nanoparticles help in better management for organic farming by using it as nano fertilisers, nanocides, nano biosensors, nano growth promoters, etc. These nanomaterials can be synthesised by three different mechanisms namely; chemical, physical, and biological methods. Since the chemical and physical mode of synthesis does not follow the criteria of organic farming and have their drawbacks. Hence, the biological method, also known as the green synthesis of nanomaterials fulfills the requirement of organic farming and has achieved the attention of researchers. Extracts of plant parts (stems, roots, leaves, flowers and, fruits) and different microbes, including bacteria, fungus, and mycorrhiza can be used as a base material for the synthesis of nanoparticles under green synthesis mode. The vision behind the green synthesis of nanoparticles was to curb the hazardous effects of chemically synthesised nanoparticles. In the present review, green synthesis of major elements of organic farming namely; nano fertilisers, nano-pesticides, and nano growth promoters, their modes of transportation, their advantages, and disadvantages in organic farming are discussed.
