Solid nitrogen fertilizers (like urea) face significant challenges: low efficiency (only 20-35% nitrogen utilized), high labor requirements (deep burial needed), crop damage risks (lodging, disease), and environmental harm (soil acidification, water pollution, greenhouse gases).

The common Urea Ammonium Nitrate solution is divided into three nitrogen fertilizer grades, with nitrogen contents of 28%, 30%, and 32% respectively. Different nitrogen contents correspond to different salting-out temperatures, which are -18℃, -10℃, and -2℃ respectively. This enables it to meet the growth needs of crops under different climatic conditions.

Urea Ammonium Nitrate (UAN) Solution offers a superior alternative:

Triple Nitrogen Advantage: Combines fast-acting nitrate-N, slow-release ammonium-N, and long-term amide-N, boosting efficiency to 90% (vs. 20-25% for solids).

Enhanced Safety: Liquid form eliminates explosive dust risks associated with solids like ammonium nitrate.

Ease of Use: Ready for direct application via irrigation, fertigation, or foliar spray – no dissolving or deep burial needed. Saves labor and energy (>30%).

Environmental Benefits: Reduces ammonia volatilization (14.8%), potent N₂O emissions (30.6%), and soil acidification risk (neutral pH 5.0-7.0).

Cost & Compatibility: Lower storage/transport costs (no caking), easy integration with automation, and compatible with many pesticides/nutrients for "one-pass" application.

Ideal for Modern Farming: UAN is key for fertigation in large-scale row crops, fruits, vegetables, and protected agriculture, aligning with global trends (US: 13.6M tons/year, rapid growth in China).

Usage Note: Dilute properly (100x for seedlings, 50x for growth), apply 3-5kg/acre per session, store away from light/heat, and combine with potassium later in crop cycles.

UAN solves core issues of solid nitrogen – inefficiency, safety hazards, and environmental impact – enabling higher yields (up to 10% in corn trials) and promoting sustainable agriculture, especially with emerging inhibitor technologies.

Yongchang offers three nitrogen concentrations: UNA 28%, UAN 30%, and UNA 32%, which can be used on virtually all crops. Click here for more packing display.
