Ted, I am curious............! Is this an established awn or is this a newer lawn? The new home sites being done here are a major joke. The properties are being filled with junk and skraped flat. Bermuda will grow on it and so will Zoysia, but for how long is the question. I have to honor your response on the state of Arkansas' test results. It seems to me that 4 of my tests from a couple years past.......on 4 different lawns virtually showed the same results and were given the same correction methods. The STATE OF ARKANSAS is adimant about using Urea--13/13/13--Dolomitic Lime on everything! LOL!!
