For what it is worth I compared your adjacant fields soil test with ours which was tested for pond usage. Your ph was 5.93 ours was 4.5 both are low. Yours is less acid. Your calcium 491 is lower than ours avg. 800 so with low calcium you have less buffering ability. The rest of the elements of the test are similar. The recomendation from our test was a total of 3 tons of ag lime per acre -- 2 tons at time of test (Oct.) 1 more ton 6 mths. later ( March). No fert. was recomended until after lime had time to work and then to slowly add powdered water sol. Pro-Sol in limited amounts to reduce visa. from 4-5 feet to 18 in. This was for existing ponds with normal levels of fish lbs. per acre ( at the time 100 lbs per acre).
Your alka. if the test is right is 17 which is below the min. requierd alka. of 20 as stated by the SRAC publications noted above. ewest
