Control Released Urea46%

Control Released Urea46%
Controlled Released Urea 46% (CRU 46%) is a high-efficiency slow-release nitrogen fertilizer with 46% total nitrogen, the core nutrient content of standard urea, upgraded with advanced coating technology. It appears as white spherical granules, featuring slow and sustained nitrogen release matching crop growth rhythms. Widely applied in grain, cash, fruit and vegetable crops, it reduces nitrogen volatilization/leaching loss, boosts fertilizer utilization rate, cuts fertilization frequency and improves crop yield/quality. Non-toxic, easy to apply and adaptable to all soils, it’s a mainstream eco-friendly fertilizer for modern agriculture.

  1. Controlled Release Principle
    The urea granules are coated with a high-performance functional material (polymer, sulfur, etc.), which forms a dense and breathable film on the surface. The film controls the dissolution and release speed of nitrogen by water penetration and microbial degradation, realizing slow release in the early stage and sustained release in the middle and late stages of crop growth.
  2. Core Agrochemical Functions
  • High-Efficiency Nitrogen Supply: 46% high nitrogen content, the same as ordinary urea, meets the large nitrogen demand of crops throughout the growth cycle.
  • Match Crop Rhythm: Customizable release period (60-180 days) for rice, wheat, corn, fruit trees, greenhouse vegetables and other crops with different growth cycles.
  • Reduce Nutrient Loss: Effectively inhibits nitrogen volatilization, leaching and denitrification, the fertilizer utilization rate is increased by 30-50% compared with ordinary urea.
  • Improve Soil & Crop Quality: Avoid excessive nitrogen accumulation in soil, reduce soil salinization and acidification; promote balanced crop growth, increase grain plumpness, fruit sugar content and commercial quality.
  • Labor-Saving & Efficient: One application for the whole growth cycle (or fewer top dressings), greatly reducing the frequency of field fertilization and saving agricultural labor costs.
