Annual Time-Release Fertilizer

For pond owners who are too busy or do not live close to their pond, time-release fertilizer may be an option.  An application is made once a year, and even though it is expensive, one bag will treat several acres.  Plankton blooms may not be as consistent with this type fertilizer.  Owners should visit their ponds occasionally to check on the water visibility.  If the pond is excessively green (visibility below 12 inches), then the fertilizer bags should be temporarily removed.

The information above came from the Alabama Wildlife and Freshwater Fisheries Division's booklet Sportfish Management in Alabama Ponds, which is available as a PDF.
