    Hi guys want to get some industry feedback and experience with my fertilization program. In Oklahoma I have usually used a low nitrogen high potash product. Any thoughts?

    I am not sure I agree with high potash. It tends to be water soluble--washes out, leaches away after about an inch of rain or irrigation. I am not sure if slow-release potash is available.
    A fully-coated nitrogen product like Koch XCU would be my choice. Or maybe an organic product--something that would not be lost in a cold winter rain. Or maybe a methylene urea product which would (in theory) only be released when soil temperatures allowed bacteria to work on it and release the nitrogen.

    And another option, I am not sure I understand how to use a nitrification inhibitor, like UMAxx. The goal being to release the nitrogen more slowly.
    Fertilizer experts--what do you think?
