    Trying to do the best thing for my customers... I have an interesting situation, and would really appriciate some input.

    temps in the 80s....
    fescue turf..
    Transistion zone..
    we've had tons of water this year... rains an average of 5 inches a week... (this week more like 15 inches.. no kidding)
    Looks like the rain will coninue.. at least in the short term.

    I appied a high nitrogen fertilizer in Feb-Mar.
    Next fertilizer treatment isn't due until sept-oct.

    I need to apply a fertilizer (or something to green the lawns) ASAP..

    I have 2 different sales reps recommending 2 different products..

    5-10-31 10FE < 10% iron, 50% slow release.

    29-5-10 UFLEX < 100% slow release.

    Assuming that price isn't the issue, and also taking into account the conditions above.. what would you choose for this later than scheduled app??

    Thanks in advance!

    i dislike the 5-10-31 blend because all the manufacturers that i have seen use MOP, but everyone has their personal opinions!


    having said that, i have used this blend before in the late summer/fall on st. augustine, the iron content helped retain color going into our winter(if you can call it that)

    never used uflexx, so no comment

    5-10-31 from MOP is garbage for turf. Good for de-icing the driveway though.

    Seriously, the Nitrogen to Iron ratio should be 3 or 4:1 I know the 5-10-31 has a lot of iron but there isn't enough N to matter & the salt in that potash will cause more stress than K could ever prepare the turf for.

    You can find many better fertilizers than either of these two but I'd use the U-FLEX if these were the only two choices.

    Seems that all of the discussion is about the 5-10-31.. here's more details about it:

    TOTAL NITROGEN (N) ..............................................5.00%
    3.90% Ammoniacal Nitrogen
    1.10% Urea Nitrogen
    AVAILABLE PHOPHATE (P2O5)..............................10.00%
    SOLUBLE POTASH (K2O) .......................................31.00%
    IRON (Fe) Total ........................................................10.00%
    0.10% Water Soluble Iron (Fe)
    DERIVED FROM: Urea, Ammonium Phosphate, Muriate of
    Potash, Iron Sucrate.
    CHLORINE (Cl) Max.................................................25.00%

    If neither of these are ideal.. what is? The 5-10-31 is from lesco... the Uflex is from BWI...

    both recommended by local sales reps..

    MANGANESE (Mn) Total...............................................................2.00%
    0.29% Water Soluble Manganese (Mn)
    DERIVED FROM: Polymer Coated Sulfur Coated Urea, Urea, Ammonium
    Phosphate, Sulfate of Potash-Magnesia, Sulfate of Potash, Muriate of
    Potash, Iron Sucrate, Manganese Sucrate.
    CHLORINE (Cl) Max .................................................................... 6.50%

    About two weeks ago, I placed on my own yard the following Lesco 5/10/31 around 4 bags , between the front and back. Since then we have had some rain in Florida, but not enough. The back yard is green and does have good growth. The front yard, well it is green but the growth is lacking. When you compair the two the back looks better.

    6.5% Chlorine is a lot better than 25%.

    But do you really need all this potash? U-FLEXX & PSCU are cheap but under certain summer weather patterns might be a major cause of grief for your lawns.

    I'd prefer a nice equal N:K ratio with Nutralene, SOP & the correct amount of Iron.

    Say: 15-0-15 50% MU, SOP, 5% Iron

    There might be room in that bag to make it a higher analysis - but not a lot.

    I'm no weather man.. but i'm betting the rain will taper off very soon.. it's been about 5 days since the last rain, and counting.. although we ALWAYS have a 30% chance... the uflex may end up being ok
