Bluegill yield in response to nitrogen and phosphorus versus phosphorus-only fertilization in ponds at different times since sediment removal

This research work provides useful information for pond managers when developing a fertilization schedule. The results of the present study do suggest that after 2 yr of nitrogen plus phosphorus fertilization, pond manager might cease nitrogen fertilization and assess the response of the phytoplankton bloom. Omitting nitrogen fertilization from ponds lessens fertilizer cost and reduces possible nitrogen pollution of nearby natural waters.
