    Just wondering if anyone actually uses uf type fert on residential customers lawns. I can see doing it to your own lawn but not to a customers.
    There to expensive(initially) and after long term use you may only have to apply one uf app per year to maintain a healthy turf. Yes, it is environmentally friendly but chances are you won't have the customer long enough to see the benefits.
    Perfect for Golf Course.
    I hope I didn't touch a nerve, I was just curious!

    If you know what you are doing and do good work. You don't have to look for customer. The customers look for you.
  3. Then you can use a high quality fert like uf.

    I think more applical on warm season turf, but I did use uf for dormant feed on bent greens in transition zone, and use some for my 1/3 total n for spring app!!!!!!!!

    I don't believe many do, Lesco doesn't sell it!

    Wonder how many knew about uf????

    I believe Arbor Green paten-ed by Davey Tree and sold by Lesco under license agreement is a UF.
  5. Is arbor green used on turf Ric?

    Don't use much lesco, not all that familiar with their products!

    Arbor Green is for trees, But will work on turf also. Most people will deep root Arbor Green Around Trees. It or course must be constantly mixed in the tank or it settles to the bottom right away. My area is all Calcareous Sand with a 5 CEC. With 55 inches of rain per year we really can't use it effectively. High ppm of Na in our well water also causes problems here. Water quality is a whole other area that we can discuss in the new Advanced Agronomy Forum that we need Sean to start. Hello Sean

    Glad you came on board Tim.
  7. surprise you have cec of 5 on sand

    I agree about advance agromony form!! Hope sean gets hint, but we need to have some resrictions on it!!!

    I am in total agreement about restrictions on it. I am sending you a private message with my toll free 800 number. We can set a time to go on Lawnsite chat room with Sean and anyone else interested in an advanced forum.

    Oops it has been a week and no one has answered the question how long.

    UF can take up to two years to break down in the soil. As stated before UF breaks down by microbial activity. Yes temperature plays a big role in microbial activity as stated before. Temperature mus be in a range for most microbes 60 to 80 degrees. In fact high temperature can cure brown patch. However so does pH play a role. Ph is one of the most important thing yet least understood. pH of 6 to 7.2 has the most microbial activity and therefore UF in soil temperature of 75 degrees and pH of 6.5 will break down faster than UF in other soils.

    OK we are still on Nitrogen someone name another source of nitrogen That we can explore

  10. I'm not done on uf

    What % of uf is hwin?

    What % of hwin in uf will breakdown in 1 year, and in 2 years?
