Title : Development and characterization of controlled release nano-fertilizer

Abstract:

Slow-release nano-fertilizers are now utilized widely to enhance nutrient usage efficiency and limit nutrient loss to the environment, which is a major drawback associated with conventional fertilizer applications. In this study, we report the development of a slow-release, macronutrient-based nanofertilizer that uses nanozeolite as a carrier. The porous nanozeolite creates a ‘barrier’ that prevents the fertilizers from uncontrolled release into the soil. Additionally, the nanozeolite itself acts as a soil conditioner. Nanozeolites were synthesized using hydrothermal method followed by loading of (NH4)2SO4 as N-source. Transmission electron microscopy was used to identify average zeolite size ranging from 80-90nm, with a somewhat cylindrical shape identified through SEM imaging. FT-IR Spectroscopy before and after loading confirmed the incorporation of nitrogen compounds in the nanozeolites. Comparative release studies showed that whilst N release from regular (NH4)2SO4 stopped within 48 hours, N release from the nanozeolite based fertilizer continued for 120 hours. Consequently the nano-sized zeolite has a 60% increase in nitrogen holding efficiency compared to regular N fertilizer, which effectively facilitates a gradual release in the soil or any other medium (e.g. hydroponics). The slow-release property of nanozeolites can be exploited to reduce the dosage of conventional nitrogen and other fertilizers and improve the soil health as an added benefit. 

Audience Take Away:

  • Site-targeted distribution of nano-fertilizers results in a regulated release of agrochemicals, decreased toxicity, and improved fertilizer nutrient use
  • Nano-fertilizers can be used not only as nutrient suppliers but also as soil conditioners as they can replenish soil and have good water holding capacity thus improve quality parameters of crops and enhance soil fertility
  • Laboratory analysis by various researchers have confirmed that nano-fertilizers are safe and non-toxic following tests on plant and animal cells, as well as impact on soil microorganisms
  • Substituting traditional methods of fertilizer application with nano-fertilizers is an effective approach that releases nutrients into the soil both gradually and in a controlled way
  • Nano and bio-fertilizers are among the modern blessings of nanotechnology by researchers to serve humanity as they are an effective solution that will increase agricultural production

Biography:

Ms. Ashita Anand studied microbiology at University of Delhi in India and graduated as BSc (Hons) in 2017 and post-graduated as MSc. Applied Microbiology from VIT, Tamil Nadu, India in 2019. She then joined as a PhD Scholar at Teri Deakin Nanobiotechnology Center, Gurugram, India. It is an in-country research program allowing students to carry out research at the Teri Deakin nanobiotechnology center in India and obtain a higher degree by research at Deakin in Australia. She is now in the final year of her PhD and in the process of submitting her research articles.
