农业级尿素肥料（氮 46%）

卡文资源 supplies premium Urea Fertilizer (46-0-0), a highly concentrated, cost-effective nitrogen fertilizer widely used in agriculture and horticulture. With a nitrogen content of 46%, it’s the most efficient solid nitrogen source, promoting rapid plant growth, leaf development, 和 high crop yields.

Our urea is manufactured to agricultural-grade standards, ensuring low biuret levels and high water solubility. It is suitable for direct application, blending with other fertilizers, or use in fertigation systems. We serve bulk buyers with reliable logistics, packaging options, and certifications for export.

⚙️ Production Method

• Synthesis – Ammonia (NH₃) reacts with Carbon Dioxide (CO₂) under high pressure
• Crystallization – The resulting urea solution is crystallized
• Granulation or Prilling – Formed into solid granules or prills
• Drying & Cooling – Ensures long shelf life and reduces caking
• Screening & Packaging – Sized for consistency and packed in bulk sacks

常见问题 (FAQ)

1. What is the nitrogen content in your urea fertilizer?

请回答：
Our urea fertilizer contains a minimum of 46% nitrogen, making it one of the most concentrated solid nitrogen sources available.

2. Is your urea granular or prilled? Can I choose?

请回答：
Yes, we supply both granular and prilled forms. Granular is preferred for mechanical spreaders; prilled is ideal for blending and fertigation systems.

3. How should I apply urea for best results?

请回答：
Urea can be broadcast on soil, used in fertigation systems, or blended with other NPK fertilizers. Watering after application helps minimize nitrogen loss due to volatilization.
