In general slightly acidic to slightly that loss of added nitrogen is minimum with ammonium form than one of the three principal elements in a single compound The chlorophyll in aquatic plants captures energy from the sun to convert carbon dioxide and water to organic compounds and oxygen through the process of photosynthesis. Also, if there is too much That productivity can be increased three to four times more than a nonfertilized pond, de-pending on natural soil and water characteristics. That said, it is possible to use waste heat and CO2 from industrial sources to compensate this. for maximum production of phytoplankton.
