Fish Pond

Farmers know that proper fertilization can greatly increase crop yields. Similarly, pond fertilization can increase fish yields three to four times. Also fish will be in better condition, and the quality of catch by fishermen usually improves.
Fertilizers used in ponds stimulate the growth of microscopic plants called algae or plankton. As primary elements of the food web, algae are eaten by microscopic animals called zooplankton and insects which serve as food for
bream, which in turn are eaten by bass.
Algae also make the water turn green, which helps to shade the pond bottom, preventing growth of troublesome rooted
weeds and filamentous algae commonly called pond “moss or pond weeds.”

Types and Grades of Fertilizer

There are many commonly used fertilizers produced for a variety of applications. Fertilizer manufacturers are required to list the grade on each fertilizer container
by the percent of
Nitrogen (N)
Phosphorus (P) as Phosphoric acid (P2O5)
Potassium (K) as Potassium monoxide (K2O).
Therefore, a 20-20-5 grade fertilizer contains 20 percent Nitrogen, 20 percent Phosphorus as P2O5 and 5
percent Potassium as K2O. “Complete” fertilizers contain N, P2O5, and K2O while “incomplete” fertilizers contain only one or two of these elements.
Common incomplete fertilizer sources are normal superphosphate (0-20-0), triple superphosphate (0-46-0), diammonium phosphate (18-46-0) and liquid ammonium polyphosphate (10-34-0).
