Soil Test Results?

I live in the north east section of Mississippi. I had my soil tested, with the following results (I have and plan on using Centipede Grass) Soil pH is 5.4 Phosphorus level is 78lbs/acre (high) Potassium level is 173 lbs/acre (medium) Magnesium level is 75 lbs/acre (high) Zinc level is 3.5 lbs/acre (high) Calcium level is 429 lbs/acre Further states that pH of soil is acid, and no lime is recommended. Can anyone break this down into simple language for me as to what this test is telling me and what I should do to have a healthy lawn? Thanks

1. Basically you have slightly acidic soil and need to stick to neutral/acid loving plants. Centipede grass will grow quite happily for you as it likes acidic conditions ideally between 4.5 to 6.0 which is what you have. If you plant any shrubs/perennials at all then try things like Rhododendrons, Azaleas, Hydrangeas, Camellias etc. The levels for the nutrients is good as long as you stick to the right plants for the PH level. http://www.agr.state.nc.us/cyber/kidswrld/plant/nutrient.htm
2. Centipede Grass grows the best with a pH of 5.0-5.5 so your soil "5.4" is good. So no lime or sulfur Centipede Grass can not handle a lot of fertilizer so I would not put out much when you do. Note that Nitrogen is not tested. It's because it leaches away and you can figure all soil is low in Nitrogen. Your Potassium and Phosphorus is good so when you buy your fertilizer get one that is high in nitrogen, the first number on the bag. Just put out a small amount. You can put out some peat moss too.
3. Your soil is good, quite rich acidic soil, and many plants will grow well in it. You will have trouble growing some vegetables, however, as they prefer more alkaline soil. The grass you are planning on will grow well in this environment. You will easily be able to find many ornamental plants -- bushes and flowers -- that will thrive.
