Agricultural urea46%

Core Functions & Agricultural Value

1. High-Efficiency Nitrogen Supply: 46% high nitrogen concentration is the highest among common solid nitrogen fertilizers, directly providing urea nitrogen that crops can absorb and utilize after slight soil microbial conversion, meeting the large nitrogen demand of crops in key growth stages (tillering, jointing, flowering, fruit expansion).
2. Wide Adaptability: Neutral to weakly alkaline property is suitable for acidic, neutral, alkaline and saline-alkali soils; applicable for base fertilizer, top dressing and foliar spraying, matching all agricultural fertilization methods.
3. Crop Growth Promotion: Promotes the synthesis of chlorophyll, protein and amino acids in crops, enhances photosynthesis, accelerates vegetative growth (stem and leaf development), improves reproductive growth (flowering and fruiting), and effectively increases crop yield and biomass.

4. Fertilizer Compatibility: Can be mixed with phosphate fertilizer, potassium fertilizer, medium and trace element fertilizers (excluding alkaline fertilizers such as lime, plant ash) to prepare compound mixed fertilizer, realizing balanced nutrient supply for crops.

   
   

Main Applications

Suitable Crops

• Field Crops: Wheat, rice, corn, soybeans, cotton, rapeseed
• Fruits & Vegetables: Apple, citrus, grape, tomato, cucumber, strawberry, Chinese cabbage
• Economic Crops: Tea, tobacco, sugarcane, beet, flowers, nursery stock

Application Methods & Dosage (per mu)

1. Base Fertilizer: 20-30kg, mixed evenly with soil before sowing/transplanting, provides basic nitrogen for the whole growth cycle of crops.
2. Top Dressing: 10-15kg per application, applied at crop tillering stage, jointing stage, flowering stage and fruit expansion stage; ditch or hole application is recommended (cover with soil after application) to reduce nitrogen volatilization loss.
3. Foliar Spraying: Dilute into 0.5-1.0% aqueous solution, spray on crop leaves in the morning or evening (avoid high temperature at noon), emergency nitrogen supplementation for crops with nitrogen deficiency (yellowing leaves).
