Loss of protective residue cover through cultivation will increase the potential risk of soil erosion. The vulnerability of the soil to erosion combined with the intensity of cultivation determines the degree to which the soil may be at risk. The classes shown on the map were ranked from 0 (lowest risk) to 1 (highest risk). This resource was created in 2002 using ArcGIS. purpose: It helps to identify areas where soil may be at risk to wind or water erosion. In areas of greater soil erosion risk, promotion of beneficial management practices such as reduced tillage, direct seeding, field shelterbelts, reduce or eliminate summerfallow, increase crop residue cover or avoid overgrazing can be encouraged. 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 degredation keyword: sedimentation keyword: soil loss 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.

Information about tillage practices was collected during the 2001 Census of Agriculture. The Census questions provided an estimate of the area of no till, conservation tillage, conventional tillage and summerfallow on farms in Alberta. Custom processing of the data by Statistics Canada yielded the percent of the land within each Soil Landscapes of Canada (SLC) polygon associated with the four management systems.
                  
SLC Version 1.9 was used for this map. SLC polygons were created using existing soil survey information. Each polygon is described by a standard set of soil and land attributes that characterizes the soil landscapes found in each SLC polygon. Soils, landscapes and climate are the key natural resource factors that determine agricultural productivity, and the farms within a soil landscape unit usually have similar production characteristics.
                  
The cultivation rating is a measure of the cultivation intensity with management systems having a greater frequency of cultivation weighted higher. The cultivation rating was calculated for each SLC polygon by the following formula: Cultivation rating = (% area in no till) x 1 + (% area in conservation tillage) x 2 + (% area in conventional tillage) x 3 + (% area in summerfallow) x 4
                  
The assessment of the soil erosion risk is based, in part, upon the potential erodibility of the soil landscape by wind and water. For this assessment, the wind erosion risk (Coote and Pettapiece, 1989) and water erosion risk (Tajek and Coote, 1993) ratings were used. Risk classes were assigned integer values to describe the wind erosion risk and water erosion risk on bare, unprotected mineral soil for each SLC. The risk classes were negligible (1), low (2), moderate (3), high (4) and severe (5). The erosion risk value assigned to each SLC polygon was the average of the corresponding wind risk value and water risk value.
                  
The cultivation rating was multiplied by the soil erosion risk value and the result ranked from 0 to 1 to form the soil erosion risk factor for each SLC as displayed on the map. dateTime: 2002-01-01T00:00:00 source: LI_Source: description: Information about tillage practices. sourceCitation: CI_Citation: title: 2001 Census of Agriculture date: CI_Date: date: 2014-03-24 dateType: CI_DateTypeCode: revision citedResponsibleParty: missing source: LI_Source: description: A series of GIS coverages that show the major charcteristics of soil and land for Canada. sourceCitation: CI_Citation: title: Soil Landscapes of Canada date: CI_Date: date: 1991-01-01 dateType: CI_DateTypeCode: publication citedResponsibleParty: missing metadataMaintenance: MD_MaintenanceInformation: maintenanceAndUpdateFrequency: MD_MaintenanceFrequencyCode: notPlanned
