I recently built a 16 acre pond with about 250 acres of run off. The pond filled in before I could lime it with ag lime so a consultant used hydrated lime. He applied it by spraying the lime on a barge behind his boat with a pressurized water hose. I know this can be risky but he did a great job and we didn't lose any fish from a sudden rise in pH. I would like to avoid using hydrated lime in the future. I have 20 acres of pasture runoff into the pond and have limed it this summer with ag lime. Do you think the pond might get a significant beneficial effect from just liming the pasture? What about fertilizing the pasture as well? I do not have any livestock on the pasture or any other agricultural runoff into the pond.
