How Nitrogen is Lost?
Nitrogen loss from fertilizers like Urea Ammonium Nitrate (UAN) solutions occurs mainly through leaching, volatilization, and denitrification, significantly impacting nitrogen efficiency and plant.
Nitrogen loss occurs through three methods, leaching, volatilization, and denitrification. UAN solutions contain three forms of nitrogen: Urea (50%), Ammonium (25%) and Nitrate (25%). Excessive moisture drives leaching of nitrates (NO3-) which occurs as water drives the nitrogen deep into the soil, out of the plant’s root zone. UAN with 50% of its nitrogen being Urea (CH4N20) is subject to volatilization or urea-hydrolysis. In this process, Urea is combined with water and forms ammonia, which evaporates into the air. Even small amounts of moisture such as morning dews can drive this form of loss.

- slows down the conversion of urea to ammonia in the soil
- What is NBPT and DMPP Inhibitors ?
NBPT (N-(n-butyl) thiophosphoric triamide) and DMPP (3,4-dimethylpyrazole phosphate) are two types of chemical inhibitors widely used in agriculture to enhance nitrogen use efficiency in fertilizers. They play a significant role in reducing nitrogen losses in soils, thus promoting more sustainable and efficient farming practices.
1. NBPT (N-(n-butyl) thiophosphoric triamide)
- Function: NBPT is a urease inhibitor. It works by slowing down the activity of urease, an enzyme in the soil that breaks down urea (a common nitrogen fertilizer) into ammonia gas. This breakdown process can lead to significant nitrogen losses, especially through ammonia volatilization.
- Mechanism: By inhibiting urease, NBPT allows more time for urea to be incorporated into the soil, reducing nitrogen loss and making more nitrogen available to plants over time.
- Benefits:
•Cost Savings :Decreases the overall cost of nitrogen application due to lower losses.
•Enhanced Crop Yield: Promotes healthier crops by ensuring a steady supply of nitrogen
2. DMPP (3,4-dimethylpyrazole phosphate)
- Function: DMPP is a nitrification inhibitor. It works by inhibiting the activity of nitrifying bacteria, which convert ammonium into nitrate. Nitrate is highly soluble in water and can easily be lost through leaching or runoff, which poses a risk to water quality and reduces nitrogen availability to plants.
- Mechanism: By slowing the nitrification process, DMPP helps retain nitrogen in the more stable ammonium form for a longer period. This gradual conversion ensures a sustained release of nitrogen, matching the crop’s nutrient requirements.
- Benefits: Enhanced Nutrient Retention, Higher Crop Yields, Economic Advantage, Environmental Protection
Comparison of NBPT and DMPP
| Feature | NBPT (Urease Inhibitor) | DMPP (Nitrification Inhibitor) |
|---|---|---|
| Target enzyme | Urease | Nitrifying bacteria |
| Primary role | Reduces ammonia volatilization | Reduces nitrate leaching |
| Nitrogen form retained | Urea | Ammonium |
| Key benefit | higher nitrogen efficiency, Enhanced Crop Yield | sustained nitrogen availability, Higher Crop Yields |
Both NBPT and DMPP are crucial in enhancing nitrogen retention and reducing environmental impact associated with nitrogen fertilizers, especially in intensive farming systems. By using these inhibitors, farmers can optimize fertilizer use, which is beneficial for both crop yields and environmental sustainability.
