Best Answer

Excess nitrogen from agriculture means using the inorganic feritilizers. These fertilizers deposit the nitrogen into the soil and overtime the soil decomposes the nitrogen, converting it into gaseous nitrogen which is then returned to the air. This eventually creates a big acid cloud which will give birth to acid rain. Acid rain will fall in the waters containing fish and then kill them.

What are the effects of too much nitrogen in a body of water?

Nitrogen has no effect on water although it can be dissolved. Nitrogen is not hazardous in itself, and in water is not dangerous. However as your body has no use for it when breathed, it can asphyxiate. But in water it has no effect on large biological organisms. High nitrogen content can cause algal blooms in surface areas of water. However, nitrogen can be processed into nitrates by bacteria which can kill fish. Excess nitrogen is removed by humans through urea.
