Nano Urea: Boosting Agricultural Productivity, Reducing Subsidy Load — A Smarter Path to Economic Growth.

Abstract

Nanotechnology has been widely used in fields such as medicine, aerospace, defense, pollution control, electronics, and paints. However, its application in agriculture has been relatively limited. Nano Urea, along with other Nano-based fertilizers such as Nano DAP, Nano NP, Bio Nutrients, and Nano Micro Nutrients, is revolutionizing the agricultural sector by increasing crop yields while reducing environmental impact. As the future of agriculture demands innovative solutions, Nano Urea stands out by significantly enhancing nitrogen use efficiency (NUE) and reducing environmental pollution and government subsidy expenses.

Traditional urea has an efficiency of only 30-50%, leading to nitrogen wastage, soil degradation, and water pollution. In contrast, Nano Urea achieves an efficiency of 85-90%, minimizing nitrogen loss through leaching and volatilization. A 500 ml bottle of Nano Urea can replace a 45 kg bag of conventional urea, reducing storage, transportation, and subsidy costs. Its controlled-release mechanism ensures a steady nitrogen supply, improving crop yields while curbing excessive fertilizer use. This article explores its advantages, economic benefits, and role in shaping the future of fertilization.

Harmful Effects of Conventional Urea on Agriculture and the Environment

1. Environmental Pollution

• Nitrogen Leaching: Overuse of conventional urea contributes to nitrogen leaching, contaminating groundwater and affecting aquatic ecosystems.
• Ammonia Volatilization: Urea undergoes hydrolysis, releasing ammonia gas, reducing fertilizer efficiency, and contributing to air pollution.
• Greenhouse Gas Emissions: Excess nitrogen leads to the formation of nitrous oxide (N₂O), a potent greenhouse gas.

2. Soil Health Degradation

• Soil Acidification: Excessive urea use alters soil pH, affecting plant growth and microbial activity.
• Reduced Microbial Diversity: Excess nitrogen disrupts beneficial soil microorganisms, impacting fertility and productivity.

3. Crop Health Issues

• Nutrient Imbalance: Urea supplies only nitrogen, potentially leading to deficiencies in phosphorus, potassium, and micronutrients.
• Phytotoxicity: High urea concentrations can be toxic to plants, reducing photosynthesis and crop yields.

What Is Nano Urea?

Nano urea is a new form of urea fertilizer that is created by breaking down conventional urea into tiny particles that are around 100 Nano meters in size. This process is achieved using nanotechnology techniques such as high-pressure homogenization and sonication. The resulting Nano urea particles have several advantages over traditional urea. They are more efficient in terms of nutrient uptake, reducing the amount of fertilizer needed to achieve the same results. They also release nitrogen more slowly, reducing the risk of leaching into groundwater and reducing the need for frequent applications.

Benefits of Nano Urea

Nano Urea offers several significant benefits that make it an essential tool for enhancing agricultural productivity while promoting sustainability. One of its key advantages is its increased Nitrogen Use Efficiency (NUE), with Nano Urea achieving 85-90% efficiency compared to the 30-50% efficiency of conventional urea, ensuring that crops utilize nitrogen more effectively. This improved nitrogen availability results in higher crop yields, promoting healthier plant growth and lush foliage. Furthermore, Nano Urea reduces overall fertilizer consumption, with just a 500 ml bottle replacing the need for a 45 kg bag of conventional urea, thus decreasing the environmental and financial burden of fertilizer use. Additionally, Nano Urea is more environmentally friendly, contributing to sustainable farming practices by reducing nitrogen pollution and minimizing the negative impact on soil health.

Nano Urea offers numerous advantages that benefit both farmers and the government while promoting environmental sustainability. One of its key environmental benefits is the reduction of nitrogen pollution in soil, water, and air by minimizing leaching, runoff, and greenhouse gas emissions such as nitrous oxide. Its cost-effectiveness is another standout feature, as it requires less quantity per acre, reducing fertilizer, transportation, and labor costs. This has contributed to a significant decline in the consumption of conventional urea in India, with an estimated drop from 375 lakh tons in FY 2023 to 327 lakh tones in FY 2024, as reported by the fertilizer Minister, Mansukh M.

Additionally, Nano Urea’s liquid formulation is compact, lightweight, and easy to store, unlike bulky conventional urea bags. The fast absorption and controlled release of nitrogen through leaf stomata ensure a steady supply of nutrients for plants, leading to better growth and higher yields. Furthermore, Nano Urea is compatible with other fertilizers and pesticides, allowing it to be combined with micronutrients and bio stimulants to cater to various crops and growth stages, making it a versatile solution for modern agriculture.

Declining Urea Consumption in Major States: An Analytical Perspective

     1.1.2 CONSUMPTION OF UREA IN MAJOR STATES OF INDIA (‘’000 tonnes)

Urea is a crucial nitrogen-based fertilizer widely used in Indian agriculture to enhance crop productivity. However, recent data indicates a decline in urea consumption across major states, reflecting a shift in agricultural practices, policy interventions, and the adoption of Nano-fertilizers like Nano Urea.

The data on urea consumption across major Indian states from 2020-21 to 2021-22 highlights a general decline, with variations in different regions. Uttar Pradesh (UP) remains the highest consumer, with 3,963.73 thousand metric tons in 2020-21, reducing to 3,745.50 thousand metric tons in 2021-22, reflecting a moderate decline. Other high-consumption states such as Madhya Pradesh (1,732.70 → 1,628.80), Maharashtra (1,699.85 → 1,594.00), and Bihar (1,285.28 → 1,159.28) also show a downward trend, indicating efforts toward optimizing fertilizer use.

A significant reduction is observed in Rajasthan, where consumption fell sharply from 1,628.80 to 1,166.55, likely due to improved nutrient management practices and increased use of Nano-fertilizers. However, Punjab and Karnataka show slight increases, with Punjab’s consumption rising from 1,495.18 to 1,573.89 and Karnataka’s from 1,179.45 to 1,237.50, suggesting continued reliance on conventional urea. Similarly, Tamil Nadu (644.85 → 675.97), Odisha (347.24 → 351.69), and Assam (175.63 → 178.46) also exhibit marginal increases, possibly due to regional agricultural demands.

Among the low-consumption states, Kerala (88.06 → 78.25), Jammu & Kashmir (114.09 → 85.41), and Uttarakhand (120.68 → 104.74) show a continued decline, reinforcing the trend of reduced nitrogen fertilizer dependency. The overall decline in several states is attributed to the adoption of Nano Urea, government policies promoting balanced fertilization, and precision farming practices. These shifts indicate a move towards more efficient and environmentally sustainable nutrient management, reducing excess urea application while maintaining agricultural productivity.

The distribution of fertilizer nutrients (Nitrogen, Phosphorus, and Potassium - N+P+K) among various crops is depicted in the following breakdown. Urea dominates the usage, accounting for 55.80% of the total fertilizer application. This is followed by DAP (Diammonium Phosphate) at 15%, and NP/NPK (Nitrogen-Phosphorus-Potassium) at 18.50%. SSP (Single Super Phosphate) and MOP (Muriate of Potash) contribute 6.60% and 2.90%, respectively. The usage of AS/ACI (Ammonium Sulphate/Ammonium Chloride) is minimal, comprising only 1.20% of the total fertilisers consumption. This data reflects the significant preference for nitrogen-rich fertilizers, particularly urea, which plays a crucial role in enhancing crop yields. The relatively smaller percentages for other fertilizers highlight their specific roles in providing essential nutrients such as phosphorus and potassium for balanced crop growth. If farmers predominantly use Urea, which constitutes 55.80% of the total fertilizer application, it can lead to several soil-related problems and environmental concerns. Excessive use of Urea often results in nitrogen imbalances in the soil, leading to nutrient deficiencies or toxicities. Over time, this imbalance can reduce soil fertility, disrupt microbial activity, and degrade soil structure. Additionally, nitrogen from Urea can leach into groundwater, leading to contamination and pollution of water bodies, which poses a risk to both human health and aquatic ecosystems.

The high application of Urea can also lead to soil acidification, which harms plant growth and soil health in the long term. The release of ammonia gas from Urea fertilizers into the atmosphere further contributes to air pollution, with the potential to cause smog formation and contribute to global warming.

In contrast, Nano Urea provides a more efficient and environmentally friendly alternative. Nano Urea has a much smaller particle size, which allows it to be absorbed more effectively by plants, reducing the overall quantity needed for the same results. This leads to a reduction in the risk of nitrogen runoff, leaching, and ammonia emissions. Nano Urea not only helps in maintaining soil health but also minimizes environmental pollution. By improving nutrient uptake and efficiency, it enhances crop yields without compromising the long-term fertility of the soil, contributing to sustainable farming practices.

Overall, using Nano Urea would not only optimize fertilizer usage, but also mitigate the negative environmental impacts associated with traditional Urea, ensuring healthier soils and reducing pollution.
