The majority of soil organic matter (abbreviated as SOM) is composed of carbon Why, then is microbial activity generally limited by carbon?
Homework Answers
-soil organic matter(SOM) is the organic matter component of
soil, consisting of plant and animal detritus at various stages of
decomposition, cells and tissues of soil microbes, and substances
that soil microbes synthesize. Soil organic matter also acts as a
major sink and source of soil carbon .
-About 58% of the mass of organic matter exists as carbon.
-Higher levels of soil organic carbon reduce bulk density, thus
providing an improved rooting environment. In addition, soil
organic matter matter holds soil water, which is an important
attribute for plant growth in arid and mesic environments.

Matter Cycling Review what it means to be an inorganic or an organic compound, and then use examples of these types of materials to summarize the carbon cycle!!! In which different spheres (biosphere, geosphere, hydrosphere, atmosphere) does carbon show up? Note that the water cycle is often thought of in terms of evaporation of surface water, cloud formation, followed by precipitation back to the earth's surface. But, this cycle is so much more complicated than that! Describe a component of...
