AGRIBUSINESS: Human urine is best fertilizer for fish pond.

Human urine is best fertilizer for fish pond. A new research shows that ponds fed with human urine generate food for fish faster by four days, while saving farmers at least 24kg of commercial fertilizer required after every two weeks. The research, which was published in the Ecological Engineering journal, said that the readiness to release the rich nitrogen and other ions in the human urine quickened the propagation process of the plankton. The Food and Agriculture Organisation (FAO) states that at least 24kg of commercial nitrogenous fertilizer must be applied per acre every two weeks to facilitate growth of zooplanktons,which are colonies of green microscopic organisms that are major sources of food for fish. A new research by the University of Kalyani, India, says half a liter of human urine is required for every 4,500 litres of water to trigger multiplication of zooplankton in four days. The research compared half a kilo of human urine with cowdung, vermicompost, chicken drippings and cow urine. In the various setups, Moina micrura plankton grew four days earlier in the human urine than the others. also
