My pastures are cross sectioned into 40 acre sections for rotating grazing. I had a soil test done that called for 60lbs phosphorus and 60lbs of Nitrogen. Just cross sectioned the pastures this year after the soil test. I have mostly coastal Bermuda with some native grasses. Some spots in each section have a good stand of Bermuda and some spots are poor. The cost of fertilizing this 160 ac piece of land is $11000! Due the the high cost of phosphorus. I want to do the best job I can to get my pastures in good shape. I live in SE Oklahoma. How would you go about improving this piece of land? I am very interested in any ideas.
