How Ammonium Sulphate Nitrate Reduces Nitrogen Loss

Ammonium Sulphate Nitrate (ASN) fertilizer reduces nitrogen loss and improves Nitrogen Use Efficiency (NUE) for sustainable agriculture by Risso.

In modern agriculture, improving Nitrogen Use Efficiency (NUE) while reducing nitrogen loss is a key challenge for farmers and fertilizer manufacturers.

Risso Ammonium Sulphate Nitrate (ASN Fertilizer 26-0-0+13S) is designed as a high efficiency nitrogen sulfur fertilizer that helps reduce nitrogen volatilization, leaching, and denitrification losses, while ensuring stable crop nutrition.

With increasing demand for sustainable agriculture, high yield crop production, and environmentally friendly fertilizers, ASN has become one of the most effective solutions in global farming systems.

1. What Causes Nitrogen Loss in Fertilizer Application?

Nitrogen loss is a major issue in nitrogen fertilizer management, especially for urea, ammonium nitrate, and liquid nitrogen fertilizers.

1.1 Ammonia Volatilization (Common in Urea Fertilizer)

When urea is applied on soil surface, it converts into ammonia gas, leading to significant nitrogen loss.

1.2 Nitrate Leaching

Highly mobile nitrate nitrogen is easily washed away in sandy soils or heavy rainfall regions, reducing fertilizer efficiency.

1.3 Denitrification Loss

In waterlogged conditions, nitrate is converted into N₂ and N₂O gases, causing both yield loss and environmental pollution.

1.4 Poor Nutrient Synchronization

When nitrogen release does not match crop demand, excess nitrogen is lost instead of being absorbed.

Major nitrogen loss pathways in agriculture including ammonia volatilization, nitrate leaching, and denitrification and how ASN fertilizer helps reduce losses.

2. What is Ammonium Sulphate Nitrate (ASN Fertilizer)?

ASN Fertilizer (Ammonium Sulphate Nitrate 26-0-0+13S) is a granular nitrogen fertilizer containing:

This combination provides both fast-acting nitrogen and stable nitrogen release, making it more efficient than traditional nitrogen fertilizers such as urea or ammonium sulfate.

3. How ASN Fertilizer Reduces Nitrogen Loss

3.1 Balanced Nitrogen Forms Reduce Leaching and Volatilization

ASN contains both ammonium and nitrate nitrogen:

  • Ammonium is held in soil particles, reducing leaching
  • Nitrate is quickly absorbed by plants
  • Balanced release reduces nitrogen waste

👉 Result: Lower nitrogen loss compared to urea fertilizer and ammonium nitrate fertilizer

3.2 Reduced Ammonia Volatilization Compared to Urea

Unlike urea-based fertilizers, ASN does not rely heavily on urease hydrolysis, significantly reducing ammonia volatilization loss.

👉 Result: Improved nitrogen retention in soil and higher fertilizer efficiency

3.3 Controlled Nitrogen Release Improves NUE

ASN contains both ammonium and nitrate nitrogen:

  • Ammonium is held in soil particles, reducing leaching
  • Nitrate is quickly absorbed by plants
  • Balanced release reduces nitrogen waste

👉 Result: Lower nitrogen loss compared to urea fertilizer and ammonium nitrate fertilizer

3.4 Sulfur Enhances Nitrogen Metabolism

The sulfur content in ASN plays a key role in:

  • Protein synthesis
  • Enzyme activation
  • Chlorophyll formation

👉 Result: Improved nitrogen assimilation and higher crop productivity

3.5 Reduced Environmental Nitrogen Loss

By minimizing nitrogen losses, ASN helps reduce:

  • Greenhouse gas emissions (N₂O)
  • Groundwater nitrate pollution
  • Soil nutrient imbalance

👉 ASN is widely recognized as a high efficiency nitrogen sulfur fertilizer for modern agriculture

How ASN fertilizer reduces nitrogen loss through balanced ammonium and nitrate nitrogen, improves NUE, and enhances sulfur nutrition in crops.

5. Best Crops for ASN Fertilizer Application

ASN fertilizer is widely used in high-demand crops:

  • Wheat
  • Corn (Maize)
  • Rice
  • Canola / Rapeseed
  • Oilseed crops
  • Cereals

It is especially effective for improving grain protein content and yield stability.

6. How to Improve Fertilizer Efficiency with ASN

Best practices for ASN application:

  • Apply during active growth stages
  • Use soil incorporation when possible
  • Avoid excessive irrigation immediately after application
  • Split application for high nitrogen-demand crops
  • Combine with soil testing for precise fertilization
Benefits of ASN fertilizer for crops, soil health, and environment including higher yield, better soil fertility, and sustainable agriculture practices by Risso.

7. Industrial & Agricultural Benefits of ASN Fertilizer

  • Higher Nitrogen Use Efficiency (NUE)
  • Reduced nitrogen loss in farming systems
  • Improved crop yield and quality
  • Better sulfur nutrition for plants
  • Lower environmental impact

Conclusion

Ammonium Sulphate Nitrate (ASN Fertilizer) is one of the most efficient nitrogen sulfur fertilizers for reducing nitrogen loss and improving crop productivity. By combining ammonium, nitrate, and sulfur, ASN ensures better nitrogen stability, reduced leaching, and higher Nitrogen Use Efficiency (NUE).

With increasing global demand for high efficiency fertilizers and sustainable agriculture solutions, ASN plays a critical role in modern crop nutrition systems.
