ewest almost identical results here. However we can get it to stay above 20 ppm for 3-4 years with 4 tons/ac unless they have high flow regimes. We due use hydrated lime ( only 3 times last year) but only if not possible to get in bulk lime.
Gator, there maybe readily available phosphorus naturally in your area, if then like Meadowlark stated lime is worth it. In GA that is not the case, many studies on effects of liming alone and little return on investment. So..it might be worth it even without fert. program. I understand fert program is tricky, but still rec. fertilization program if in GA low productivity soils without or feeding program you just have very few fish/acre.
