    I know when and why to fertilize in the fall, I'm just confused on what I should be looking for in a fertilizer for the fall. Should I be using the generic winterizer or should I be putting on straight urea (46-0-0)

    and yes I have my chemical license.

    Any suggestions?

    Thanks!

    There is no right or wrong answer to your question. I prefer to apply a product with a 5-1-2 combination ie (28-5-12, 24-5-11 or higher N 32-5-7). Some locals might limit your phosphates usage but for the fall its not a bad thing have. It just depend whether you program is agronomic or economically driven. I know guys that follow the clean out my shop of all fert in fall and winter program :).

    Cool-season grasses utilize the most N in the Fall for getting ready for Winter... 46-0-0 is typically sold as slow release and I don't think those pellets should still be intact when snow comes... I believe that a pound of N per k being utilized before dormancy is what is required...
    Here in Centro Wisco we are already past the time of useable fertilizer for this season...

    Generally, I like to provide some K at this time of year in addition to N. Hard to say without knowing your location, type of grass, and some kind of history on the place(s).

    46-0-0 is usually never sold as a slow release, usually refers to as a all mineral.

    I'll have to double check... I haven't bought that stuff for years now, but I recall it as lasting 2-3 months...

    The stuff I put down this Fall was 23-0-6 and it was slow release for 2 months... It has been about 2 months but there has been so little rain that I'm not sure if it is getting dissolved efficiently...

    What did you mean about being "all mineral"???
