This article examines the role of controlled-release fertilizers in reducing groundwater pollution and protecting water resources.

Groundwater Pollution Problem

One of the most important challenges of modern agriculture is water source pollution due to chemical fertilizer leaching. In Iran, which faces water scarcity, protecting water resources is of particular importance.

Mechanism of Controlled-Release Fertilizers

Controlled-release fertilizers with polymer or resin coatings release nutrients in a controlled manner and prevent their rapid leaching.

Research Results

Based on studies conducted:

  • 60% reduction in nitrogen leaching
  • 50% reduction in phosphorus leaching
  • Protection of groundwater quality
  • Reduced water treatment costs

Case Studies

In various regions of Iran such as Khuzestan, Isfahan, and Khorasan, the use of controlled-release fertilizers has led to improved groundwater quality.

Impact on Sustainable Agriculture

Controlled-release fertilizers not only prevent environmental pollution but also contribute to agricultural sustainability by improving fertilizer use efficiency.

Conclusion

The use of Adib Gostar Arvand's controlled-release fertilizers can play an important role in protecting Iran's water resources.
