I have 9000 sq ft of St.Augustine lawn in Central Florida and I just found out my soil is very acidic at ph 5.6 and I need to apply 48 pounds of lime per 1000 sq ft. Here is my soil test results from the state soil extension lab. http://alturl.com/thzw I want to get back to neutral soil as quickly as possible and I went out and bought some Encap Fast Acting Lime. Here is the product... http://retail.encap.net/Home/Products/LawnCare/tabid/94/FastActingLime.aspx This thing was 2 or 3 times more expensive than regular calcitic lime. (I can't use dolomite lime as my magnesium in the soil is already WAY too high) How good is this "Fast Acting Lime" and how soon can I expect to see results after I lay it down? I am planning on laying down all 14 bags of it at once. For my 9000 sq ft lawn that was 420 pounds total to get around the recommendations to get me back neutral. I will also be putting down some bifenthrin granules to treat for confirmed chinch bug infestation as well. I will be using one bag of this... http://www.lesco.com/NoCompression/GetData.aspx?Type=ProdResource&ID=3810&.pdf Am I headed in the right direction? Encap claims that their product is 4 times more effective than regular lime. So should I apply less of it than recommended in my soil report then? I don't plan on adding any fertilizer at all right now. I just want to see the results of neutralizing my soil on its own so it can get at whatever nutrients are already there. Then later on in a few months I may put down some fertilizer. I really want to see the proof of how important soil ph alone really is in lawn condition. My lawn has been struggling for years even though I was fertilizing it with good products at the correct rates. The pros told me it was because of the soil being too acidic for it to really thrive was the reason why I didn't get much results out of the good fertilizer I was putting down. Any input appreciated. Thanks for all input.
