Nanotechnology refers to the science and application of materials at the nanoscale (1-100 nm), where particles exhibit unique physical, chemical, and biological properties. In agriculture, these nano-sized materials make farming more productive and sustainable.
Nanotechnology offering significant advancements in agriculture
Nano-fertilisers improve nutrient-use efficiency to 90-100% – boosts yields. Eg- Nano-urea and nano-DAP introduced by IFFCO.
Controlled-release nano-pesticides reduce chemical load, minimise residue on crops, and improve efficacy against pests. Eg- nano-Silver
Bridging micronutrient deficiency – Eg- Nano Zinc and Nano Copper liquids.
Enables nanoscale gene delivery – quickly and safely transport DNA into plant cells – Improves crop breeding
Soil health improvement – Nano-clays and nano-zeolites enhance soil moisture retention and restore degraded soils in dry regions.
Crop Protection – Applying silica nanoparticles to leaves shield plants from high temperatures.
Precision agriculture – Nanosensors monitor soil moisture, nutrient levels, and plant health.
Post-harvest protection – Nano-coatings on fruits and vegetables extend shelf life by 2-3 times.
Irrigation efficiency – Nanomaterials remove contaminants and improve water quality for irrigation.
Seed quality enhancement – Nanopriming improves seed vigour and early germination.
Nano-Biosensors can identify plant diseases at an early stage through biomarker detection
Food Packaging – Eg- use of nanocomposites in making antimicrobial and oxygen-barrier coatings – reduce spoilage and food waste.
Role of nanotechnology in uplifting the socio-economic status of farmers
Reduced input costs – Nano-fertilisers cut fertilizer usage by 50%
Higher yields and productivity due to improved nutrient uptake by crops
Nano-coatings and nanosensors reduce post-harvest losses (currently 15-20%).
Improved climate resilience – nano-enabled seed treatments help stabilise production during droughts, heatwaves, and soil degradation
Access to premium markets – Residue-free nano-pesticides help farmers sell to export markets with strict safety standards.
Local production of nano-inputs, nano-coatings, and sensor devices can generate rural micro-enterprises and FPO-led businesses.
Health and environmental benefits – Reduced chemical use lowers health expenditures, improves soil fertility, and supports sustainable long-term income.
Challenges of Nanotechnology in Agriculture
High cost and limited awareness of nano-inputs limit large scale adoption.
Nanophytotoxicity can hinder plant growth, reduce photosynthesis, and affect seed germination.
Bioaccumulation concerns – Nanoparticles may accumulate in vital organs through food chains, with unclear long-term health effects.
Groundwater contamination risk due to leaving of Mobile nanoparticles into aquifers.
Toxicity to pollinators – Continuous exposure to nanoparticles through pollen can harm bees.
Lack of regulatory standards – India lacks clear biosafety guidelines and permissible limits
Pollution risks as Non-biodegradable nanoparticles may remain in ecosystems.
