Nanotechnology for the Future of Agriculture: A Short Review


The use of nanotechnology in the agricultural sector

Attempts to use nanotechnology in agriculture are beginning with the growing understanding and realization that conventional farming techniques will not be able to increase efficiency or re-establish ecosystems that have been affected by current technologies to their original state; In particular, due to the long-term effects of cultivation with chemical fertilizers and pesticides. In this article, we will cover the base of nanotechnology for its application, its prospects and future challenges.

What is nanotechnology

Nanotechnology is the study and management of matter at the nanoscale, where unique phenomena offer revolutionary applications, with dimensions ranging from 1 to 100 nanometers. Nanotechnology involves the efficient processing and control of nanoparticles.

Nanotechnology has made significant contributions to sustainable agriculture by increasing crop yields and restoring and improving soil quality.

Nanotechnology is used in a variety of agricultural applications, including:

  • nanopesticide delivery

  • The nanoparticles containing the biofertilizer are released gradually and in an orderly manner.

  • Application of nanobiosensors for rapid detection of plant pathogens and other biotic and abiotic stress factors in crop growth.

Nanoparticles used in the agricultural sector

Below are some of the nanoparticles commonly used in the agriculture sector.

polymeric nanoparticles

Polymeric nanoparticles are used in agriculture to deliver agrochemicals in a gradual and orderly manner. Polymeric nanoparticles have several advantages, including greater biocompatibility and less impact on non-target species.

silver nanoparticles

Silver nanoparticles are widely used as antimicrobial agents against a wide range of plant pathogens. Silver nanoparticles have also been shown to improve plant growth, according to the researchers.

nano alumino– silicate

As an effective pesticide, many chemical companies use nanotechnology aluminoSilicate formulations.

carbon nanoparticles

To improve seed germination, carbon nanoparticles including graphene, graphene oxide, carbon dots and fullerenes are used.

Other nanoparticles used in agriculture include copper oxide, zinc oxide, nanoparticles, and magnetic nanoparticles.

Improving crop productivity through agricultural nanotechnology

Non-herbicides, nano-fertilizers, nano-sensors, and nano-pesticides are some examples in which nanotechnology has been used to enhance crop productivity.

Nano pesticides

The use of nano-herbicides and nano-pesticides to control weeds and pests has greatly improved agricultural production. Nanoparticles of different types, such as polymeric nanoparticles and inorganic nanoparticles, are used in nanoherpesicide formulations.

Nanomaterials for disease management

Every year, huge agricultural losses are incurred as a result of microbial infections (viruses, fungi, bacteria). Nanomaterials with antimicrobial properties help prevent microbiological invasions.

nano fertilizer

To combat nutrient deficiencies in plants, scientists have used nanotechnology to build a smart delivery system that distributes nutrients in a gradual and orderly manner to the target site. Nano-fertilizers increase crop production by increasing the availability of vital nutrients to the plant.

nano sensors

When compared to conventional biosensors, nanosensors are more sensitive and selective.

Nanosensors provide real-time signal monitoring and are used to directly or indirectly identify pathogenic microorganisms.

Prospects and challenges in the application of nanotechnology to agriculture

Nanotechnology will revolutionize the agricultural sector and food industry by developing new technologies such as climate-smart agriculture, increasing plant nutrient uptake, using more efficient and effective inputs, and disease detection and management.

The main interest in nano-enabled products is the potential future amounts of nanoparticles used as they have been found to have negative effects at various levels at elevated doses. The continued use of nano-enabled products, particularly in agriculture, has the potential to increase the number of nanoparticles in soil and crops. This will eventually lead to a negative impact on health.
