Daniel Baker said: Have you considered any of the Duration blends? I love my 0-0-50 on the greens and 0-0-58 on tees and fairways. They make them in several blends and with 120,180,270 day releases
Duration and Polyon are almost identical products.
I've used almost strictly Polyon or Duration products for my bulk feeds over the past 10 years. This past summer, we applied on May 6th with a 180 day Polyon blend. The Polygraph shows it petering out in about another week. In my past experience, when the Polygraph says the feeding will drop below the maintenance levels, you better have another application lined up. Never had it last any shorter than what I was told. Even so, it will continue feeding us for another 8-10 weeks at about .04#N/m.
As for price, it's actually cheaper than using traditional products like UMaxx, XCU or SCU. Think of it this way, why apply a product three times when you can apply Polyon(or Duration) once? Also, instead of applying 3#N/m over the course of a season, you can achieve the same results using about 2#N/m of Polyon. Therefore, if you are looking at a product that is +/-$95/ac, but you have to apply it three times, then how is that cheaper than applying a Polyon or Duration product that is +/-$170/ac only once per season? We've seen a savings and so will you.
In my opinion, UMaxx will also move out of the soil quicker, especially on sandy soil, without any uptake during periods of heavy rain.
