This chapter discusses soil organic matter. Organic matter is universal to all soils. The form and distribution of soil organic matter is dependent upon a number of processes that may act independently or in concert. Most of these processes are related to the initial decomposition of the plant residues by a suite of soil fauna, and to the continued ...

The organic matter content of lake sediments provides a variety of indicators, or proxies, that can be used to reconstruct paleoenvironments of lakes and their watersheds and to infer histories of regional climate changes. Organic matter constitutes a minor but important fraction of lake sediments.

This article summarizes a cultural perspective on trade associations and its implications for understanding their organizational features, roles, and functions. I suggest that fruitful future research should examine over time the conditions under which particular association activities become consequential, and compare trade association organization ...

In this chapter the general processes involved in controlling production and transformation of organic matter will be discussed as well as some of the associated stoichiometric changes of a few key biological elements (e.g., C, N, P, S). Stoichiometry is defined as the mass balance of chemical reactions as they relate to the law of definite proportions

Soil organic matter (SOM) is probably the most important constituent of soils. The effect of SOM on soil properties far exceeds the relative percentage of this material in soils. The small amount of organic matter in soils, usually from 1 to 5%, is very important in providing a reserve food source for microorganisms and higher plants.

Soil organic matter includes plant and animal residues at various stages of decomposition, ranging from fresh undecomposed materials through partially decomposed and short-lived products of decomposition to well-decomposed humus. Plant and animal residues contain sugars, celluloses, hemicelluloses, proteins, lignins, waxes, and lipids.
