The phosphorous cycle is considerably different from the nitrogen cycle. Rather than a predominantly biochemical cycle, the phosphorous cycle is basically a geological cycle. This is because the major reservoir is the lithosphere, with the principle inputs from the erosion and weathering of phosphorous deposits. Large amounts of phosphorous are eroded and washed into the rivers, lakes, and oceans. Runoff [...]
In this article we will discuss about:- 1. Introduction to Nitrogen Cycle 2. Forms of Nitrogen 3. Sources 4. Biochemical Conversion Processes. Introduction to Nitrogen Cycle: Nitrogen, in a number of different forms, can play an important role in several environmental problems. Like many chemical compounds, nitrogen is cycled in nature from one form to another, with losses in one [...]
The Sulfur Cycle: Sources, Acid Deposition and Mining Techniques! The sulfur cycle includes both a very slow geologic component between land and water, and rapid atmospheric and biologic components. Like the other nutrient cycles, sulfur is also a requirement of life. However, due to its environmental abundance, this element is rarely a limiting one. Organisms use sulfur in both its [...]
