Easy greening

Anuvia Plant Nutrients’ John Fowler offers tips for making spring applications of the company’s high-efficiency GreenTRX fertilizer.


Combining a significant amount of ammoniacal nitrogen with sulfur and iron, Anuvia Plant Nutrients’ GreenTRX fertilizer flashes a green-up within days and provides long-lasting control thereafter. The product’s 16-1-2-17S-3Fe Organic MaTRX augments the practices superintendents begin to put in place when spring arrives.

“It comes without a lot of extra growth, which you’re trying to prevent, because you already have a big carbohydrate reserve pushing, because plants want to grow in the spring anyway without our help,” says John Fowler, Anuvia national accounts director. “But what’s unique about our fertilizer is that we give it that pop and that color without a whole lot of extra growth.”

Other fertilizers that contain ingredients such as ammonium sulfate provide a quick release, but then the results fade, Fowler says. GreenTRX, by comparison, utilizes both quick- and slow-release properties. Results will usually first appear within five to nine days after application. One superintendent said he saw results within a single day.

Application strategies for GreenTRX differ depending on numerous factors, including region, soil type, temperature and grass height, Fowler says. “What I can say, unequivocally, is it really works — our GreenTRX works very quickly,” he says. “It’s very, very fast. And it has a tail on it depending on what your soils are.”

Typically, in the South, superintendents should apply around one pound of nitrogen per thousand square feet, or around 300 pounds per acre, Fowler says. In the North, superintendents should apply between three quarters of a pound and a pound per thousand square feet, or between 200 and 300 pounds per acre.

Soil type determines GreenTRX’s length of control, Fowler says. The fertilizer usually lasts six to eight weeks in areas with clay soils, such as Pennsylvania and Ohio, while it usually lasts four to five weeks in areas with sandy soils, such as Florida. “I’m thinking of Fort Lauderdale and Naples; they just have such sand that they’re dealing with,” Fowler says. “What I’ve found — it still lasts, but not as long as it would in Philadelphia.”

In areas where grass goes dormant, superintendents should make their first spring application of GreenTRX when temperatures have been in the 50’s for several days, which could be in February, March or April, depending on the region.

Superintendents can apply GreenTRX with their normal spreading equipment, Fowler says. “That’s what’s also kind of unique, is you don’t have to do anything special for our product,” he says. “It’s just like you would spread any other fertilizer. We have different sized products for greens applications, fairways and rough. So we just line up your SGN size with what surface you’re going after and use your normal equipment.”

GreenTRX leaves a positive impact on the environment, Fowler says. For each pound of the fertilizer superintendents put on their golf courses, they are removing a pound of organic waste from the environment. Plus, Fowler says, GreenTRX is safe. “We’ve tried to burn turf with it,” he says. “We can’t.”
