WebDec 16, 2024 · Nitrification can occur naturally in unburned ecosystems, too. However, altered soil conditions in fire-affected areas could “have some impacts on the way that these microbes are processing... WebMar 3, 2024 · Too much nitrogen and phosphorus in water can lead to an overgrowth of free-floating plants such as duckweed and filamentous algae, resulting in dense layers of scum on the surface of the water. This can damage aquatic plants, fish, and other lake organisms by depriving them of the oxygen and sunlight they need to survive. (Credit: James Fischer)

WebJul 23, 2024 · The processes of nitrification and denitrification produce a potent greenhouse gas called nitrous oxide (N 2 O). But about 40% of the N 2 0 in the atmosphere is due to human activities. For example, agriculture can result in more nitrogen in the soil. More nitrogen in the soil means more nitrification and denitrification. WebSuccession following a period of chronic disturbance ( i.e. prolonged agriculture) does not follow such clear patterns; the duration and intensity of disturbance may control whether nitrogen availability and potential nitrification increase or decrease early in such seres.
