    Dang that sure looks like a lot of growth for using a slow release product. Is there really any height difference of the grass between regular fert and the one ap product you used? They sure claim less clippings and growth but you picts look scary to me. I'm contemplating using some on 400k of grass I have but am a bit leary to just spread the stuff and hope it doesn't eat my lunch on the mowing end.

    Any thoughts on setting for full rate? 6? We are more comfortable running around in circles. I think we might cause more problems by chris/crossing. I may try it on one one the smaller lawn we SOLD this to..

    Bart,

    The One AP as with all the SiFi approved products, are blended with some quick release N. One AP is 90%Duration CR a polymer coated urea. 8% of the nitrogen is derived from ammonium sulfate, 2% from urea. It may not seem like much but when applied at the recommended spread rate 1/3LB of quick release nitrogen is applied per 1000 sq ft. Additionally some of the Duration is Type 45 so depending on the weather some of it will begin releasing. The goal of One AP is to perform everyday during the growing season. Since the desire is to have dark green grass in the spring itÂ’s necessary to design a product that would give results in a cool spring.

    it is not any more tall using the one app than any other lawns we are mowing right now after going thru the rounds again this week. they are however very green. i think that shot of amonium really did the trick to get things rolling out of dormancy. i dont think my second pic attached so i am going to repost it here and try

    So would you say that in 3-4 weeks when the amm. sulfate wears off you could expect to see the growth slow down but still maintain a nice green lawn?

    Yes, the goal is to design One AP to mimic a conventional program without the peaks and valleys. However, depending on application timing and spring weather the initial kick can vary a bit. Earlier the application the better so the release will ramp up as the ground temperatures increase. After the ammonium sulfate release is done then the Duration takes over and the release is very consistent. The spring kick out will be equal to a conventional program. For the spring, if you suddenly have warm wet weather then you may see a typical surge as you would a convention fertilizer. Comparing to a conventional as Grassman is doing is the best way to evaluate. This year, many markets are having an early quick warm up so this may be a little more present than the last two years where we had cooler springs.

    Tim summed up what i think perfectly. we did have a rapid warm up and the first out the gate greening came first with the amonium. but it is by far not growing any more than my conventional program is now. just to clarify as many questions as possible. i will take more pics after a wek or two past my rd 2 has been in effect and watered in.


    to be honest, i am only worried about the cavalcade being as effective as my normal barricade app than the fert not performing like it should. i have always been weary of generic AI. i am sure it will be fine though

    FYI for 8# per k of SIFI the settings for the Z-Spray are 6.5 on the impeller speed and 6.5 on the hopper opening. For lesco push it should be "I" setting to get 8lbs..I will take pictures as well....I applied this on my home lawn 2 weeks ago and have not seen any major growth. But it is early for upstate NY...
