3. CONTENTS Introduction What is Nanotechnology Nanoparticles Nanofertilizer Types of Nanofertilizer Research work Work in india Futuristic Strategies Conclusions

4. Introduction Agriculture is the backbone of most developing countries. In agriculture the main reason to use fertilizer to give full-fledged macro and micro nutrients which usually soil lacks. Traditional farming techniques have attained saturation and are neither able to increase productivity nor able to restore ecosystems damaged by existing technologies . To attain a sustainable growth in agriculture to meet the food security challenges, ‘ Nanotechnology ’ can be one of the source.

5. What is Nanotechnology? “Nanotechnology is the art and science of manipulating the matter at nanoscale ”. Nanoscience and Nanotechnology are the study and application of extremely small things conducted at the nano scale, which is about 1 to 100 nanometers . It has recently gained attention due to its wide applications in different fields such as in medicine, electronics, environment, agriculture, textile etc.

6. Nanotechnology Origins The concept behind this principle originated in a talk entitled, “There’s Plenty of Room at the Bottom” by Richard Feynman a noble laureate in physics in 1959 ,in which he described the possibility of synthesis via direct manipulation of atoms. The term “Nanotechnology” was coined by Professor Norio Taniguchi .

7. A  nanoparticle   or  ultrafine particle  is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. Nanoparticles Fig 1. Schematic representation of different types of nanoparticles

8. Properties of nanoparticles Owing to their very small size, nanoparticles have a very large surface area to volume ratio when compared to bulk material. This feature enables nanoparticles to possess unexpected optical, physical and chemical properties. F or example, surface area, cation exchange capacity, ion adsorption increases when they are brought to nano -size.

10. Applications of nanotechnology in agriculture

11. These are analytical devices having at least one dimension no greater than 100 nm. T hese are structured as nanoparticles, nanotubes, nanowires or nanocrystals . NBSs are manufactured for monitoring plant fractions, soil and water in the agro ecosystem . By exploiting the physico -chemical properties of nanomaterials , NBSs represent a powerful tool with advanced and improved features compared to existing analytical sensors and biosensors that combine biological element recognition with chemical or physical principles.

12. NANOFERTILIZERS Any Product that is made with nanoparticles or uses nanotechnology to improve nutrient efficiency in the form of fertlizers . Benefits Quality improvements Improve soil activity Balanced nutient suppy Eco friendly

13. Some examples of possible control mechanisms

14. nanoherbicide Nanoherbicides are formulated by exploiting the nanotechnological potential for effectural delivery of chemical or biological herbicides with the help of nanosized preparations or nano -materials-based herbicide formulations .

15. Nanopesticides Nanopesticides offer a range of benefits including increased efficacy , durability , and a reduction in the amounts of active ingredients that need to be used .  At nanoscale , particles have a disproportionately large surface area relative to their overall size. It’s the surface area that makes the difference, because the greater surface area ratio means more of the total volume of pesticide comes into contact with the pests. And that in turn means being able to reduce the amount of pesticide needed .

18. Disadvantages of Nano fertilizers The Catchy term ‘Nanotechnology’ also pose some risk and problems towards the health and also towards environment. When considering risk and safety interm of the same will be relevant only certain area. The initial studies performed for nano materials have caused serious health hazardsand also showed toxic effects.

23. India's efforts in Nanotechnology Development

24. Work in India IFFCO, one of the world's largest fertilizer manufacturing cooperatives, has manufactured products with nano -technology to improve the productivity of farms including nano -nitrogen, nano -zinc , and nano -copper .   IFFCO claims that Nano nitrogen, Zinc, and Copper let the farmers use a lesser amount of fertilizers in their farms and also increase the yield of the crop. These three nano products will enhance the quality of soil and are environment-friendly . And will also help farmers to obtain better yielding, reducing the use of traditional fertilizers by up to 50 percent. This way, it will also reduce the cost of farming.   The cost of a 500ml bottle of Nano Nitrogen, Nano Zinc, and Nano Copper is about Rs 240. 

25. According to ASSOCHAM India ranks 3rd in R&D in the field of nanotechnology after China and USA. India is expected to contribute about 25% professionals out of required two million professionals in Global Nanotechnology Industry. IIT Madras has used nanotechnology for arsenic decontamination of water.  A team of scientists at IIT-Kanpur have engineered nanoparticles rich in iron and sulfur to pump up crop productivity.

26. Futuristic Strategies for Sustainable Farming Using Agricultural Nanotechnology

27. policy options for the application of nanotechnology for sustainable development of agriculture are:

28. conclusion:   Nanotechnology would prove a boon for modern agriculture farming by improving the efficiency of nutrient uptake employing nano -fertilizers, control of pest and pathogen using nano -pesticides, etc. Nano-sensors are being developed that spread throughout the farming fields for monitoring agro-climatic. The applications of nanotechnology have great potential to meet out the future agricultural challenges such as food security . Thus, agro-nanotechnology would be an eco-friendly, cost effective green technology for sustainable agriculture.
