These activities create ammonia. Some bacteria in the water change this ammonia to produce nitrite which is then converted by other bacteria to nitrate. Nitrates (NO3-) are an oxidized form of nitrogen and are formed by combining oxygen and nitrogen.Nitrates also come from the earth.Soil contains organic matter, which contains nitrogen compounds. Just like the ammonia in water, these nitrogen compounds in the soil are converted by bacteria into nitrates.hese activities create ammonia.
