Nano Urea: A Smart, Sustainable Fertilizer Solution
Introduction
Efficient nutrient management is a growing priority in agriculture. Nano urea brings nitrogen to plants in ultrafine, liquid form, reducing waste and boosting productivity. Its targeted delivery and ease of application make it an attractive option for modern farms.
What Is Nano Urea?
Nano urea is a liquid nitrogen fertilizer produced through nanotechnology. Unlike granular urea, which loses a significant portion of its nitrogen to leaching, volatilization and runoff, nano urea adheres to leaf surfaces and penetrates plant tissue more effectively. This precision means plants receive the right amount of nitrogen exactly when they need it.
Benefits for Growers
-
Enhanced Nitrogen Uptake: Nanoparticles enter through stomata and move systemically, cutting losses and improving efficiency.
-
Yield Improvement: Trials report yield increases of 15–20% across cereals, vegetables and pulses when nano urea supplements or replaces conventional urea.
-
Reduced Input Costs: One litre of nano urea can substitute for a 45 kg bag of granular urea, lowering transport and storage expenses.
-
Environmental Benefits: Less runoff protects groundwater, while diminished greenhouse gas emissions support climate-friendly farming.
-
Soil Health Preservation: Foliar application reduces soil nitrogen overload, helping maintain balanced microbial communities.
Mode of Action
Sprayed as a foliar spray, nanoparticles smaller than 100 nm cling to the leaf surface. As plants transpire, these particles enter through stomata, then distribute via xylem and phloem to roots, shoots, flowers and developing fruits. This ensures a uniform nutrient supply throughout the plant.
