    Talked to an applier today who works for a very large ferttilizer company. Asked him what he was putting down, and he told me a weed and feed %40 N, and at a rate of 2.5lb Nitrogen per thousand. He said late fall it will be %60 at 4.0 - 4.25 lb per thousand. Am I crazy, but these are really high Nitrogen apps? He said all apps were a quick release N, with the exception of the mid summer app. These numbers do not look like the reccomendations from Purdue. No wonder I am mowing hay after the guy comes around.

    I guess I care if I have to mow a lawn 2 or three times, or bag a bunch of grass because of tremendous growth. I am glad the stuff is growing and all, but the people who are not even fertilizing are growing now, and only take half the time to make the same money.

    This is why I don't mow any lawns unless I do the fertilizing also.... screw that.

    2.5 Lbs of N would be absurd! Leaf Spot, then later Snow Mold would destry whats left of the turf.

    That would mean he was applying a granular 40%N at 6.5lbs/M. I think the applicator was yanking your chain.

    Whether liquid or granular, I doubt even the least scrupulous would through their money away on bad agronomics.

    I'll wager the real N rate was more like 1.5Lbs N/M. And that's just fine for most home lawns at or around the time the lawns are going dormant. Though it would be a little too heavy around here right now.

    Oh yeah, one more thing.

    Only anhydrous ammonia gets any where near 60%N. And its around 80% I think. Urea's as high as it gets for N for most lawn care uses at 46%N.

    That applicator didn't have a clue what he was talking about.

    Any chance he was thinking about straight Muriate of Potash? That would be 0-0-62. There are a few guys who use this for their last app because it's wicked cheap. We're talking something like $10 per acre. But it's not going to make the lawn grow.

    But it will make the checking account grow!

    It's true this fella did not seem overly bright. He maybe completely ignorant, he did not seem to be lying. It is hard to tell, a good liar does not seem to lie. When he was telling me about all that Nitrogen, I asked him of the grass was able to store all that N til Spring, which he said caused quick green up, and he said Yep! He was putting down grannulated.

    I talked to another big LCO same day who is good friends with another huge Applicating co., and asked him a few questions, and ranted about the high N app.s that the other Fert Company was doing, and he said Ya gotta load up the N to combat brown spot/brown patch. He said yeah man, ya got to pour it on. I thought over fertilizing was a main reason for brown patch, but what do I know.

    Maybe I am ment to learn the trade and help some of these unsuspecting people. :)

    Thanks

    Large amounts of soluble N during warm whether WILL CAUSE Brown Patch.

    Now that it's cool, the logic behind applying large amounts of N could only be to aid in recovery of previous damage.

    But this approach won't have an impact on the future liklihood of Brown Patch.

    And it may cause Leaf Spot if we're talking about cool season grasses here.
