Organic N that is present in soil organic matter, crop residues, and manure is converted to inorganic N through the process of mineralization. In this process, bacteria digest organic material and release NH4+-N. Formation of NH4+-N increases as microbial activity increases.
The term 'decant' is usually associated with wine. Decanting is also a chemical laboratory process used to separate mixtures. Answer: Decanting is a process to separate mixtures. Decanting is just allowing a mixture of solid and liquid or two immiscible liquids to settle and separate by gravity.This process can be slow and tedious without the aid of a centrifuge.ome mixtures that can be decanted: 1  Oil and water-oil floats on top of water. 2  Decanting the mixture allows the oil to be poured off the water. 3  Gasoline or kerosene and water-this mixture is an example often cited as a safety hazard.
Decanting can be used o separate a liquid from an insoluble solid. As the solid settles to the bottom of the container, the liquid can be carefully poured into another c â¦ ontainer leaving the solid (sediment) behind.   Decanting can also be used to separate two immiscible liquids like oil and vinegar.
