    I always used a 4-1-2, so usually a 16-4-8, on centipede.

    What's in the bag? I make 4-1-2 or any other analysis as needed. N source? K source? Micronutrient source? P is usually MAP or DAP.

    Why so much P on centipede. Unless there is a deficiency, excess P will cause a condition where micronutrients are locked up within the grass.

    The soil where I was was almost exclusively sand, so anything we put down was gone almost immediately.

    You can get away with plenty on sand. Which is why I pitch a fit when the "landscaper" brings in truckloads of dirt to paste over sand to install a landscape. :hammerhead: My dire warnings about what needs to be done apply when there is red clay layered over sand and coral.

    We use 15-0-8 with micros. N source is ammonium sulfate. K source is sulfate of potash. Works really well on st aug and centipede.

    What dealer do you get this blend from?

    I've been trying to heed the advice from Ralmroad and Greendoctor but can't find a fertilizer with both ammonium sulfate and potassium sulfate.

    No urea in there? Are the micros chelated or just sulfates and oxides?

    Just sulfates and oxides, baby! I'll list the label when I look at a bag again.
