Slow Release Urea (SRU) Fertilizer

Product Name: Slow Release Urea (SRU) Fertilizer
Other Names: Controlled Release Urea, Enhanced Efficiency Fertilizer (EEF)
CAS Number: 57-13-6

🌱 Product Overview

Slow Release Urea (SRU) is a high-efficiency nitrogen fertilizer designed to release nutrients gradually over time, aligning with the nutritional needs of crops throughout their growth cycle. By reducing nitrogen loss through volatilization and leaching, SRU maximizes nutrient uptake while minimizing environmental impact.

✅ Key Benefits

• Controlled Nutrient Release: Delivers nitrogen over weeks or months, reducing the need for multiple applications.

• Higher Efficiency: Minimizes losses due to leaching, denitrification, and volatilization.

• Eco-Friendly: Supports sustainable agriculture by reducing nitrogen runoff into waterways.

• Labor-Saving: Fewer applications mean lower labor and operational costs.

• Consistent Growth: Promotes uniform crop development with steady nitrogen supply.

📦 Typical Composition

• Total Nitrogen (N): 46%

• Release Duration: 45 to 120 days (depending on coating type and conditions)

• Available in:

  • Polymer-Coated Urea (PCU)

  • Sulfur-Coated Urea (SCU)

  • Urea-Formaldehyde or Urea Aldehyde

🌾 Application Areas

• Cereals (rice, wheat, maize)

• Fruit orchards & vegetables

• Turfgrass, golf courses & landscaping

• Controlled environment agriculture (CEA)

• Suitable for both basal and top dressing

📦 Packaging Options

• 25kg woven PP bags with liner

• 500kg / 1000kg jumbo bags

• Custom packaging available

🧪 Storage & Safety

• Store in a cool, dry, well-ventilated area

• Avoid direct exposure to sunlight and moisture

• Use gloves and protective gear when handling

🔍 Product Description:

Slow Release Urea (SRU) is a next-generation nitrogen fertilizer engineered to provide consistent nutrient availability over an extended period. Unlike conventional urea, which releases nitrogen rapidly, SRU utilizes advanced coating technologies such as polymer coatings, sulfur coatings, or biodegradable materials to delay nitrogen release, matching plant uptake rates more closely and increasing overall nutrient efficiency.

It is ideal for commercial agriculture, horticulture, turf management, and environmentally sensitive areas where nitrogen loss can be a major concern.

🌿 Types of Slow Release Urea Available:

1. Polymer-Coated Urea (PCU) – Offers precise and long-term nitrogen release, excellent for crops with longer growing seasons.

2. Sulfur-Coated Urea (SCU) – Cost-effective, with sulfur acting as a secondary nutrient.

3. Urea-Formaldehyde (UF) – A chemically bonded form that decomposes gradually through microbial activity.

4. Dual-Coated Urea (Sulfur + Polymer) – Combines the benefits of both coatings for enhanced performance.

✅ Advantages:

• Reduces frequency of fertilizer application

• Improves nitrogen use efficiency (NUE)

• Minimizes risk of nutrient burn and leaching

• Enhances crop yield and quality

• Environmentally sustainable

• Lower labor and operational costs over time

🌱 Applications:

• Agricultural crops (grains, oilseeds, sugarcane)

• Vegetable and fruit farming

• Greenhouses and nurseries

• Golf courses, parks, and sports turf

• Forestry and landscaping projects
