Nanotechnology involves the engineering of molecules and atoms, connecting subjects such as Physics, Chemistry, Informatics, and Biotechnology. It is the science of creating extremely small machines. Although not yet widespread in the agricultural sector, nanotechnology holds promise due to its benefits in the food system and crop protection. Presently, this technology is also playing various roles in improving the quality of soil and water quality.

Abiotic stresses, particularly drought and salinity, are the most prominent constraints that can seriously impact plant growth and crop production, posing a direct threat to the food supply needed to meet the increasing demands of a growing global population. Nanotechnology plays a promising role in modern agriculture by improving plant growth and enhancing abiotic stress tolerance. It achieves this by increasing hormonal production, enhancing photosynthesis pigments, and activating antioxidant enzymes to reduce oxidative stress.

Its working mechanism includes:

Salinity and Drought Stress - Nanoparticles (NPs) can indeed mitigate the effects of salinity and drought stress on plants. These stresses cause various harmful changes in plants that affect growth and productivity. NPs can help plants cope with these stresses by inducing positive physiological and biochemical responses.

Routes of NP Entry - NPs typically enter the plant system through roots and leaves. Once inside, they interact with the plant at cellular and subcellular levels, which can lead to beneficial changes in the plant’s morphology and functions.

Heavy Metal Contamination - Heavy metals in the soil can significantly impact crop production. Nanotechnology provides solutions, including foliar sprays, which enhance plant resistance to heavy metal toxicity.

Nanofertilizers - These are specifically designed to enhance nutrient uptake, reduce losses, and improve crop quality and yield. They frequently incorporate various types of nanoparticles—such as cerium, silicon, carbon, and titanium dioxide—that are known to promote plant growth while minimizing environmental risks.

Penetration and Transport of NPs - Comprehending how nanoparticles penetrate and move within plants is essential for unlocking their full potential. This understanding contributes to the development of nanotechnology applications that enhance agricultural productivity and promote sustainability.

Moreover, nanotechnology can enhance agricultural water management. Learn how:

Nanofiltration for clean irrigation water - Nanotechnologies can effectively clean irrigation water by removing impurities and treating and recycling effluent. Specifically, nanofiltration membranes can make irrigation water acceptable for crops by eliminating pollutants and contaminants. This process swiftly removes pesticides, fertilizers, and pathogens using magnetic nanoparticles, carbon nanotubes, and nanofilters, allowing the water to be reused for irrigation.

Improving soil water retention- Hydrogels, nanoclays, and nanozeolites enhance the soil’s water-holding capacity. By doing so, they reduce the duration of water shortages during the crop season. Both organic and inorganic nanomaterials have the ability to absorb pollutants from the environment, leading to improved soil remediation and reduced treatment costs and time.

Advanced disease detection and water quality monitoring - Nanobarcodes and nanoprobes coated with antibodies can rapidly and precisely identify plant diseases caused by bacteria and viruses. Additionally, nanosensors allow for real-time monitoring of water quality parameters such as pH, temperature, dissolved oxygen, and nutrient levels. Coatings of silver nanoparticles prevent microbial buildup on irrigation pipes, plastic film, and greenhouse glass, thereby extending the lifespan of farming infrastructure and preventing deterioration.
