The primary objective of soil classification is to divide the soil into various categories such that all the soil in a particular category has similar characteristics and nature. The primary source of SOM is vegetal detritus. In forests and prairies, for example, different organisms decompose the fresh detritus into simpler compounds. This involves several stages, the first being mostly mechanical, and becoming more chemical as decomposition progresses. The microbial decomposers are included in the SOM, and form a food web of organisms that prey upon each other and subsequently become prey. heron shop walker
