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. purpose: Soil organic matter is derived primarily from the decomposition of plant biomass. It improves both the physical and chemical properties of soil and has beneficial effects on agricultural soil quality. status: MD_ProgressCode: completed resourceMaintenance: MD_MaintenanceInformation: maintenanceAndUpdateFrequency: MD_MaintenanceFrequencyCode: asNeeded descriptiveKeywords: MD_Keywords: keyword: Alberta type: MD_KeywordTypeCode: place descriptiveKeywords: MD_Keywords: keyword: soil chemistry keyword: plant litter keyword: soil fertility type: MD_KeywordTypeCode: theme thesaurusName: CI_Citation: title: Agrovoc date: CI_Date: date: 2016-01-21 dateType: CI_DateTypeCode: revision citedResponsibleParty: missing descriptiveKeywords: MD_Keywords: keyword: Downloadable Data thesaurusName: uuidref: 723f6998-058e-11dc-8314-0800200c9a66 resourceConstraints: MD_LegalConstraints: useConstraints: MD_RestrictionCode: license otherConstraints: Your use of this information will be governed by the terms of the Open Government Licence - Alberta, in force as of the date you accessed the information , found at http://open.alberta.ca/licence resourceConstraints: MD_LegalConstraints: accessConstraints: MD_RestrictionCode: otherRestrictions otherConstraints: To access the data you must agree to the terms of the Open Government Licence - Alberta found at http://open.alberta.ca/licence resourceConstraints: MD_LegalConstraints: useLimitation: Distribution Liability: Under the terms of the Open Government Licence - Alberta, the Information is licensed as is, and the Information Provider excludes all representations, warranties, obligations, and liabilities, whether express or implied, to the maximum extent permitted by law.

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. metadataMaintenance: MD_MaintenanceInformation: maintenanceAndUpdateFrequency: MD_MaintenanceFrequencyCode: notPlanned
