Koch Agronomic Services

Professional-grade turf care is a fine art. But it takes scientific brainpower to grow vibrant green turf that stays green longer.

There's a Science to Greener Turf

Koch Agronomic Services is a global leader in enhanced efficiency fertilizer products. Our Ph.D. agronomists, chemists and technical specialists put advanced solutions to the test for maximized nutrient performance.

We move technologies beyond the ordinary by working with universities, government researchers, international research centers and private organizations to provide the best evaluation in diverse conditions and environments. The result is a trio of turf and ornamental products—UMAXX® and UFLEXX™ stabilized nitrogen and HYDREXX® nitrogen stabilizer—that are engineered to be the smartest path to greater green.

Adding Knowledge to Nitrogen

One of the most essential nutrients for healthy turf is nitrogen. It's also a significant challenge due to the fact that more than 40% of nitrogen can be lost within the first days after application.

There are a few ways that nitrogen loss occurs. A primary source is ammonia volatilization, when urea-based fertilizers are applied on the soil surface. If the nitrogen is not moved into the soil through rainfall or irrigation, a natural enzyme known as urease breaks the nutrient into ammonia gas which is then lost to the atmosphere.

Nitrate leaching happens when water moves nitrogen below the root zone, making it unavailable for plant uptake. When soil is saturated, nitrification is also a risk. In this process, nitrogen is converted into a gaseous form that diffuses out of the soil.

UMAXX® and UFLEXX™ stabilized nitrogen and HYDREXX® nitrogen stabilizer are made to provide the best scientific protection so your nitrogen can work more effectively.

Made with both urease and nitrification inhibitors, UMAXX® stabilized nitrogen fertilizer provides triple-action protection against all three forms of nitrogen loss—volatilization, denitrification and leaching. Specially intended for use where extended feeding and reduced repeat applications are desired, it helps nitrogen remain available for up to 12-16 weeks.

Like UMAXX® stabilized nitrogen fertilizer, this product contains both urease and nitrification inhibitors for triple-action protection against all three forms of nitrogen loss—volatilization, denitrification and leaching. The key difference is that UFLEXX™ stabilized nitrogen is made with lower concentrations of each inhibitor to accommodate uses where repeat applications are desirable. Nitrogen remains available for up to 6-8 weeks.

A dry, soluble fertilizer additive, HYDREXX® nitrogen stabilizer gives you flexibility to modify your own liquid urea-based nitrogen for short- to medium-duration performance. The stabilizer maximizes fertilizer efficiency by protecting against all three forms of nitrogen loss.
