In the realm of modern agriculture, the excessive use of conventional nitrogenous fertilizers like urea has led to a skewed NPK (Nitrogen, Phosphorus, Potassium) ratio, posing significant challenges to soil health, environmental sustainability, and crop productivity. However, amidst these challenges emerges a revolutionary Agri-input - Nano-Urea, leveraging the power of nanotechnology to transform the way we nourish our crops.

Challenges of Conventional Urea Usage:

Conventional urea fertilizers, while widely utilized in global agriculture, come with their own set of drawbacks. With urea accounting for over 82% of nitrogenous fertilizers applied to crops globally, the sheer magnitude of its usage poses significant concerns:

1. Low Use Efficiency: The low utilization efficiency of urea, ranging from 30-40%, not only results in economic losses for farmers but also compromises the health of soil, air, and water bodies.
2. Environmental Impact: Excessive application of urea leads to environmental degradation, including soil acidification, nitrate leaching, and contamination of groundwater, posing a threat to aquatic life and human health.
3. Crop Susceptibility: Overuse of urea fosters excessive foliage growth, making crops more susceptible to pests, diseases, and lodging, thereby reducing overall agricultural productivity.
4. Pollution: The conversion of urea into harmful nitrogen oxides (nox) contributes to air pollution and exacerbates climate change, undermining global efforts to limit temperature rise and achieve sustainable development goals.
