TTRU® Controlled Release Urea – The Choice Technology for Fall Fertilizer Versatility

TTRU™ controlled release/polymer coated urea from Allied Nutrients is an extremely versatile fertilizer technology. First, it offers four different longevities: 60, 90, 120, and 180 days release (at 70˙F). These diverse options allow you to tailor your turf management program to fit your nutritional objectives and best optimize your operational costs (ie. labor and materials). The temperature responsiveness of TTRU further increases your flexibility and assures you get the most from your fertilizer investment.

A feature of TTRU is that its release rate responds to temperature, meaning nutrients release more quickly when it’s hot, and slow down when it’s cool. Cooling fall temperatures result in a lot of great options for using TTRU to manage your turf’s nitrogen supply. A shorter longevity product like TTRU60® can provide all the N your turf needs to get through the fall but a higher longevity product like TTRU90® or longer can do the same, but also offer nutrient storage that can safely carry over into the spring. With the optional TTRU longevities and your chosen application timing, you can control how much N you want to release in the fall and how much you want to have available for your turf in spring, see the chart below for examples of how fall application timing can affect spring nutrition.

Chart Summary: This chart illustrates the varied color response of a 90-day PCU applied in either September, October, or November. Great fall response from September application due to relatively warm weather. Less fall response when applied in October (cooler), and very limited response from November application. In spring, brief response from Sep application, but Oct and Nov applications resulted in successively longer spring response due to significant nutrient carry-over. Based on your fall and spring turf management objectives, application timing is key to nutrient use and extended release.
