    The temp is supposed to be in the 30's tonight so this will keep the
    ground cold.

    Ammonium Sulfate is what you need this time of year on the Fescue.

  6. Back on subject...What is the rate to get 4 week post control on crabgrass? lbs of ai / acre...since their are more than one formulation of dimension!

    crab will not germinate until the soil has remained 55 degees for more than 72 hours, and still needs moisture. When in gc business, I would apply pre emerge within several days of the soil reaching 72 degrees...always measured at sunrise, and at thr 3 INCH DEPTH

    Im still tank mixing atrazine in fl with 75 degree weather during the day, you should be fine just make sure your rates are correct.

    The old UHS, Now UAP have an Atrazine 4L with no heat limitations. I have spot treated in 90 degree weather and had no ill effects. I do apply it at lower than normal rates in that weather condition.

    I'm in central Nc and put out ammonium sulfate on my fescue in early March. The grass looks the best it probably has looked, deep green and thick. I probably put between one and two pounds of nitrogen per 1000sqft. Even though I don't have a soil test do you have any recommendation to keep it looking this nice. Last year I put out triple 17 in early spring and fall and it didn't look as good as this year. Thanks for any info.
