The Nitrogen Cycle and its Processes

Ammonification is also termed as the decaying process. It occurs when the plant or animal dies then decomposers such as fungi and bacteria decompose the tissues and transforms the nitrogen back into ammonium. The ammonium then reenters the nitrogen cycle where it is taken up by plants and other microorganism for development. Get price

16.4G: The Iron Cycle

Aug 15, 2020Iron (Fe) follows a geochemical cycle like many other nutrients. Iron is typically released into the soil or into the ocean through the weathering of rocks or through volcanic eruptions. The Terrestrial Iron Cycle: In terrestrial ecosystems, plants first absorb iron through their roots from the soil. Iron is required to produce chlorophyl, and plants require sufficient iron to perform photosynthesis. Get price

How Backwashing Filters Work – Pure Water Products, LLC

For reduction of iron and manganese, under the right conditions. As iron media go, Birm is relatively light in weight and hence easy to backwash. It is also low in cost, so it's a popular iron medium although it has some drawbacks. A pH of at least 6.8 is normally required for Birm to remove iron. Calcite. To increase the pH of acidic water.
