Title: Organic Matter Content of Cultivated Soils
Dataset Publication Date: 2005-09-01
Abstract: This map displays the percentage of organic matter in the surface layer of cultivated soils in the agricultural region of Alberta. Soil organic matter (SOM) is derived primarily from the decomposition of plant biomass. SOM improves both the physical and chemical properties of soil and has beneficial effects on agricultural soil quality. SOM is reported on the map as a percentage using the following classes: less than 2 (very low), 2 to 4 (low), 4 to 6 (medium), 6 to 8 (high) and greater than 8 (very high).This resource was created in 2002 using ArcGIS.

Data Quality Information
Scope (quality information applies to): Dataset
Data History: Data used in this map comes from Norwest Labs and was presented in a study conducted by Norwest Labs and Alberta Agriculture and Food (AF). The study looked at distribution of soil fertility parameters, including SOM, on an ecodistrict basis. Ecodistricts are land areas that "are characterized by distinct assemblages of landform, relief, surficial geological material, soil, water bodies, vegetation and land uses" (Ecological Stratification Working Group, 1995). The Norwest Labs database represented 77,962 records from 1993 to 1997. Producers submitted soil samples taken at a depth of 0 to 30 cm. An average SOM value was calculated for each ecodistrict and then assigned to classes ranging from very low to very high.
