Sulfur Coated Urea SCU Description
Sulfur Coated Urea (SCU) is a high-efficiency nitrogen fertilizer coated with a layer of sulfur to regulate nitrogen release and supply essential sulfur nutrients. This innovative fertilizer technology enhances nutrient use efficiency, reduces nitrogen losses, and improves soil health—helping farmers achieve better yields with fewer applications.
Key Features
Controlled Nitrogen Release: The sulfur coating slows down nitrogen dissolution, providing a steady supply of nitrogen to crops over an extended period.
Sulfur Supplementation: Supplies essential sulfur, a vital nutrient for plant protein synthesis and enzyme function, improving crop quality and growth.
Reduced Nutrient Loss: Minimizes nitrogen loss from volatilization, leaching, and denitrification, increasing fertilizer efficiency and reducing environmental impact.
Improved Soil Fertility: Sulfur coating promotes soil microbial activity and enhances nutrient availability.
Wide Crop Compatibility: Ideal for cereals, vegetables, fruits, and other major crops.
Easy Application: Suitable for soil application and compatible with most fertilizer spreading equipment.
