Answer:
Any metabolic waste product that contains nitrogen. Urea and uric acid are the most common nitrogenous waste products in terrestrial animals; freshwater fish excrete ammonia and marine fish excrete both urea and trimethylamine oxide can be called as nitrogenous waste.
Explanation:
We can take various measures to reduce amount amount of nitrogenous waste that enters in rivers and oceans:
• Improved Nitrogen Management reductions depends on the initial and revised practices and on weather and other management factors.
• Winter cover crop effectiveness depends on their establishment which varies with weather and other conditions.
• Controlled drainage reductions are higher when more drain flow occurs during the controlled period.
• The effectiveness of Drainage water recycling, Bioreactors, and Constructed wetlands depends on the storage volume relative to the crop area being treated.
• Two-stage ditches can remove thousands of pounds of nitrate, but the effectiveness percentage is limited because they usually only treat a fraction of the nitrate present.
Thus, we conclude nitrogenous waste can be managed in different ways.
