Fertilization can often increase the pounds of fish a lake can support by two to four times that of an unfertilized lake by stimulating plankton production, which is the foundation of aquatic food webs.  Plankton should be dense enough to cause a white object to disappear from sight at 18 to 24 inches in most ponds.  This density will not only provide plenty of food for invertebrates and small fish, but also help shade out nuisance plants.  Care must be taken, however, not to fertilize unwanted plants that are already established.

Fertilizer application in our area should usually begin in March, when water temperatures reach 60°F.  The fertilizer should be thoroughly dissolved and spread evenly to prevent it from becoming tied up in the mud on the lake bottom.  PFS has equipment designed to ensure fertilizer is applied correctly.
