TTRU™ Controlled-Release Urea Technology

Controlled Nitrogen Release for Lasting Turf Performance

TTRU™ is a polymer-coated urea technology, supplied by Nu-Tec, with four longevity options that help turf managers match nitrogen delivery to seasonal performance requirements.

Getting Nitrogen to Perform Beyond Application

Turf requires consistent nutrition over time. TTRU™ is designed to help reduce peaks and valleys in nitrogen availability, unwanted growth flushes and burn potential while extending nutrient availability.

A Controlled-Release Approach to Turf Nutrition

TTRU™ is a polymer-coated urea technology available in 60-, 90-, 120- and 180-day longevity options, allowing the release profile to be matched to different feeding windows and turf programs. The coating controls how quickly nitrogen moves from the granule into the surrounding soil.

How TTRU™ Regulates Nitrogen Release

  1. Moisture Enters the Coating

    Soil moisture passes through the polymer coating and into the fertilizer granule.

  2. Nitrogen Dissolves Within

    The nutrient dissolves inside the coating, creating a concentrated solution within the granule.

  3. Nitrogen Moves Into the Soil

    Dissolved nutrients diffuse through the polymer coating into the surrounding soil solution.

  4. Release Continues Over Time

    Temperature and coating thickness regulate the release rate, creating TTRU™ options designed for 60-, 90-, 120- and 180-day feeding periods.

Greater Control Across the Fertilization Cycle

Controlled release helps maintain a more consistent nutrient supply while giving turf managers greater flexibility in how they build a fertilization program.

Consistent Nutrition

Gradual nitrogen release helps reduce peaks and valleys in nutrient availability and unwanted growth flushes.

Durable Coating

The coating is designed to remain intact through transportation, blending and application.

Reduced Loss Potential

Controlled release helps reduce the potential for nitrogen loss through leaching, denitrification, runoff and volatilization.

Flexible Longevity

Four longevity options support different feeding requirements: 60 days for shorter feeding windows; 90 and 120 days for progressively extended nitrogen delivery; and 180 days for the longest controlled-release window.

Where TTRU™ Technology Fits

TTRU™ is suited to golf, sports turf, and commercial and residential lawn care applications where extended nitrogen delivery is required.
