Soils of the Organic order are the dominant wetland soils found in forested regions of Canada. Their greatest extent is in the low-lying landscapes of the Hudson Plains ecozone but they occur in wetlands throughout the boreal forest.

Soil organic matter (SOM) is the organic matter content 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 (Brady & Weil, 2008).

A typical agricultural soil has 1–6% organic matter by weight. It consists of three distinctly different parts: living organisms, fresh residues and molecules derived from well-decomposed residues. These three parts of soil organic matter have been described as the living, the dead and the very dead.
Define soil organic matter and list its main components. Evaluate the importance of organic matter on soil physical, chemical and biological properties and processes. Explain the sources and turnover processes of soil organic matter. Discuss the spatial distribution and land management of soil organic matter.

Soil organic matter is the fraction of the soil that consists of plant or animal tissue in various stages of breakdown (decomposition). Most of our productive agricultural soils have between 3 and 6% organic matter. Soil organic matter contributes to soil productivity in many different ways.
Organic soils are defined in the Canadian System of Soil Classification as soils that have developed largely from organic deposits. Most Organic soils develop under saturated conditions and are derived dominantly from vegetation that grows in poorly and very poorly drained areas.
