Usage of Nanotechnology in Agriculture

  1. 1. NANOTECHNOLOGY USED IN AGRICULTURE Uva Wellassa university of Sri lanka 1
  2. 2. Introduction • Nanotechnology refers to controlling, building, and restructuring materials and devices on the scale of atoms and molecules • A nanometer (nm) is one-billionth of a meter 2
  3. 3. Nanotechnology for Crop Biotechnology • Three-dimensional molecular structures • DNA crystals • The DNA crystals have “sticky-ends” or small cohesive sequences • lattice-like structure that extends in six different directions, forming a three-dimensional crystal • This technique could be applied in improving important crops 3
  4. 4. Nanoparticles and Recycling Agricultural Waste • Nanotechnology is also applied to prevent waste in agriculture Ex: - cotton industry Cotton fabric or garment waste (cellulose or the fibers ) Low -valued products (cotton balls, yarns) 4
  5. 5. Fertilizer or pesticide absorbent • Scientists produce 100 nanometer-diameter fibers • It can be used as a fertilizer or pesticide absorbent • The technique is called as electrospinning • These high-performance absorbents allow targeted application at desired time and location. 5
  6. 6. Ethanol production • Ethanol production from maize feedstocks has increased the global price of maize • Cellulosic feedstocks are now regarded as a viable option for biofuels production • Nanotechnology can enhance the performance of enzymes used in the conversion of cellulose into ethanol 6
  7. 7. • Scientists are working on nano-engineered enzymes that will allow simple and cost-effective conversion of cellulose from waste plant parts into ethanol 7
  8. 8. Disposal of rice husk • Rice husk can be used as a source of renewable energy Rice husk Thermal energy A large amount or bio fule of high-quality nanosilica Making other materials ex :- glass, concrete • Through nanotechnology can reduce the growing risk of rice husk disposal concern 8
  9. 9. Nanotech Delivery Systems for Pests, Nutrients, and Plant Hormones • Nanosensors and nano-based smart delivery systems could help in the efficient use of agricultural natural resources like water, nutrients and chemicals through precision farming. • Through the use of nanomaterials and GPS with satellite imaging of fields, remotely detect crop pests or evidence of stress such as drought. 9
  10. 10. • Once pest or drought is detected, there would be automatic adjustment of pesticide applications or irrigation levels. • Nanosensors dispersed in the field can also detect the presence of plant viruses and the level of soil nutrients. • Nanoencapsulated slow release fertilizers have also become a trend to save fertilizer consumption and to minimize environmental pollution 10
  11. 11. • Nanobarcodes and nanoprocessing could be used to monitor the quality of agricultural produce • Through nanotechnology, scientists are able to study plant’s regulation of hormones ex:- auxin – induce root growth and seedling establishment • Has developed a nanosensor that reacts with auxin • It can measure auxin concentration at a particular point using electric signal • It helps to understand how plant roots adapt to their environment, especially to marginal soils 11
  12. 12. Recent Developments • The scientists have planned to develop a plastic storage bag lined with nanoparticles • A milk container was designed with a nanopatterned, antimicrobial coating that helps the diary farmers • The scientists have planned to develop nanopatterned paper sensors to detect bovine pregnancy to determine if the cows will run dry without milk due to udder infection or pregnancy 12
  13. 13. Impacts of nanotechnology in agriculture • Have many potential applications in a variety of fields • Carbon nanotubes can be used to recognize and fight viruses and other pathogens • However, results of studies in animals have raised concerns about the potential toxicity of nanoparticles 13
  14. 14. Conclusion • Nanotechnology is capable of being used in agricultural products that protect plants and monitor plant growth and detect diseases • Scientists are still seeking new applications of nanotechnology in agriculture and the food industry • The agricultural sector and the food industry will indeed see tremendous changes for the better in the coming years 14
  15. 15. 15 Thank you
