AESA soil quality benchmark sites

The development of a province-wide network of benchmark sampling was initiated in the spring and summer of 1998 by the Conservation and Development Branch of Alberta Agriculture, Food and Rural Development (AAFRD). Monitoring of these benchmark sites is part of the AESA (Alberta Environmentally Sustainable Agriculture) Soil Quality Monitoring Initiative.

Initially, 2 goals were identified for this program. The first to determine the state of soil quality across Alberta and the second to determine the risk of change in soil quality with various management practices. A third goal to determine how soil quality integrates into environmental sustainability was added to the soil quality program strategy in 2001.

The main objectives of the fall benchmark sampling across Alberta are to:

• provide baseline soil information
• evaluate landscape effects on soil quality and soil quality risk assessment
• provide a data set to test and validate simulation models (crop growth, wind and water erosion)
• monitor changes in soil quality over time on a field landscape basis

1992-2002 Soil quality study

In the late 1980s, questions concerning trends in soil quality and means of measuring those trends, if detectable, arose in response to the issue of sustainable agriculture. To address this, Agriculture and Agri-Food Canada established the Soil Quality Benchmark Site Study as part of the 1990 Soil Quality Evaluation Program.

By 1992, a network of 23 benchmark-monitoring sites across Canada were established, including 4 in Alberta, and various land, soil and air characteristics were monitored in Alberta for at least 10 years. Funding for the study ended following the 10-year resampling of the sites in 2002-2003.

Current Status of Soil Quality Study

Upon completion of data transfer agreements authorized in 2022 custodianship of the samples and soil property data was moved to the University of Alberta, Department of Renewable Resources, Environmental Soil Science.

Guides

The Alberta Fertilizer Guide provides information on the use of fertilizers under the various cropping and soil-climate conditions throughout the province. Farmers are encouraged to use it in conjunction with soil tests and their own experience to develop an effective and economic fertilizer program. The guide covers cropping practices, soil types and map, problem soils, fertilizers types, rates and timing and application methods by crop type.

The Nutrient Management Planning Guide for Alberta is a resource for developing field-scale nutrient management plans. The primary objective of this guide is to facilitate nutrient management planning in Alberta. Information within the guide draws from theory, critical procedures and Alberta-specific considerations. The guide is laid out in 8 modules that address specific topics.

Soil names

Characterization of soil types and the establishment of limits to the geographical distribution of each soil type name (soil name) within Alberta. Updates to this version include incorporating new soil names created since the release of the 2006 edition, and modifications to some soil correlation areas boundaries.

Soil Correlation Area map

The Soil Correlation Area (SCA) Map of Alberta (PDF, 1.5 MB) illustrates the boundaries that define the geographic distribution of the soil names associated with each SCA.

Land suitability

The Land Suitability Rating System (LSRS) reference tool offers guidance for using the LSRS computer program. It describes the processes followed for developing the system and offers guidance for interpreting an LSRS rating.

Alberta landforms

The Alberta Landforms report presents background information on the landform classification system used within the Agricultural Regions of Alberta Soil Inventory Database (AGRASID). The report highlights quantitative morphological descriptions and landform classifications for typical glaciated landforms in western Canada. It also documents the methods used to produce the descriptions.

Land resource atlas

The Agricultural Land Resource Atlas of Alberta is a collection of agricultural resource maps developed as part of the Environmental Scan for Agriculture in Alberta by the Alberta Environmental Scan Technical Team in 2003. The maps in the atlas were prepared for the environmental scan process (PDF, 39 MB). They are a valuable resource of environmental information, in particular for Alberta’s agricultural community for the development of environmental farm plans.
