2. Key Applications

Animal Feed Additive

Provides dual phosphorus and non-protein nitrogen nutrition for ruminants (cattle, sheep), with slower nitrogen release than conventional urea.

High-Efficiency Fertilizer

62% total nutrient content (N+P) suitable for alkaline soils, showing 15-20% yield improvement in rice and wheat crops.

Industrial Uses

  • Flame retardant in polymer materials
  • Metal surface treatment agent
  • Phosphate purification agent

3. Usage Guidelines

Feed Additive Protocol

Recommended dosage: 1-1.5% of total feed weight. Gradually mix into feed to ensure uniform distribution.

Fertilizer Application

Apply 300-400 kg/hectare during soil preparation. Compatible with most NPK fertilizers but avoid alkaline mixtures.

4. Industry Case Studies

Case 1: Hubei Chenghai Chemical

Implemented urea phosphate in cattle feed (1.2% concentration), achieving 18% weight gain improvement over 90 days with zero ammonia toxicity incidents.

Case 2: Shenzhen Xingkaiyue Bio-Tech

Utilized as flame retardant additive in polyurethane foams, achieving UL94 V-0 rating at 15% loading capacity.

Case 3: Jiangsu Shayingxi Industrial

Applied in rice cultivation (350 kg/hectare) on alkaline soils, resulting in 22% yield increase compared to conventional fertilizers.
