Contemporary formulations of urea for sustainable agriculture:

Urea is globally the most commonly utilized nitrogen fertilizer, extensively employed in agriculture practices, although it faces many issues such as significant nutrient loss through volatilization and leaching, thus causing pollution and decreased nutritional efficiency.

The selection of foliar fertilizers is a critical step in agricultural production, directly impacting crop growth and yield. Urea, a common foliar fertilizer, is widely used across various crops. other fertilizers like potassium dihydrogen phosphate, boric acid, and amino acids are also available. Is urea the optimal choice? This article provides a detailed analysis.

I. Basic Characteristics and Advantages of Urea

1. Chemical Stability

   • Urea is a white, crystalline solid with high chemical stability, resistant to decomposition or spoilage. This ensures safety during storage and reduces risks from chemical reactions.

2. High Water Solubility

   • Urea dissolves rapidly and completely in water, enabling quick absorption by plants and improving fertilization efficiency.

3. Fast-Acting

   • Nitrogen in urea is rapidly absorbed by plants, significantly boosting growth. This makes it a popular choice for top-dressing applications.

4. Cost-Effective

   • Urea is affordable due to its abundant raw materials and simple production process, offering economic benefits to farmers.

5. Versatile Application

   • Suitable for cereals, cash crops, fruit trees, and more, making it widely applicable in agriculture.

6. Ease of Storage and Transport

   • Its stable physical form resists environmental changes, simplifying logistics in agricultural supply chains.

II. Comparison with Alternative Foliar Fertilizers

1. Potassium Dihydrogen Phosphate (KH₂PO₄)

   • A compound fertilizer providing phosphorus and potassium. It supports comprehensive crop development but acts more slowly than urea.

2. Boric Acid

   • Enhances disease resistance and fruit quality but requires prolonged use to show effects.

3. Amino Acids

   • Promotes balanced crop growth but is costly and less efficient than urea.

III. Key Considerations for Urea Use

1. Avoid Overapplication

   • Excessive urea can elevate soil osmotic pressure, hindering root water uptake and risking root burn. Control dosage to prevent damage.

2. Combine with Other Fertilizers

   • Pair urea with phosphorus or potassium fertilizers to enhance nutrient balance, improve efficiency, and reduce environmental impact.

3. Prevent Skin Contact

   • Urea is mildly corrosive; handle with gloves to avoid skin irritation.

Urea remains a top choice for foliar fertilization due to its speed, cost-effectiveness, and versatility. optimal results depend on crop needs, soil conditions, and budget constraints. Rational use—avoiding overreliance and combining with complementary fertilizers—maximizes benefits while minimizing risks.
