Whoa! Don't do any of that until you get this test read. Do this Google search (logan labs andy10917 soil management) and find the forum where Andy reads the Logan Labs soil tests. Post your results there and explain what you were planning to do (tilling). Let those guys talk you out of tilling or give you a way to do what you really need done.

The test was read already and that was the recommendations I recieved. Ill do a search for andy and see if he can help with a second opinion. They charge you $30 and have your samples read by a third party. I called them up and he seemed very knowledgeable. Explained to me why I needed all that stuff. He was saying that my potassium and phosphorus were my 2 main focuses that are way off and that the gypsum was for the really high amounts of magnesium in the front yard. That it would soften the soil and help it leach from the soil if that makes sense. He kept talking and I tried to write as fast as I could. He said to work on that this year and retest next year and we will go from there. But he said if I was going to till to add 20-25 lbs per 1000 of rock phosphate and that would be a slow release of phosphorus for years to come.

Forget about tilling. Andy will tell you why. Andy doesn't charge $30 and he gives you a written reply which you can respond to if you have further questions. That forum is free like this one.
