This report describes two sites (Site ID #2-615, 802) that were added to the original benchmark sites to form the soil and landform classification project being conducted by Alberta Agriculture, ... More ≫

Description

This report describes two sites (Site ID #2-615, 802) that were added to the original benchmark sites to form the soil and landform classification project being conducted by Alberta Agriculture, Food and Rural Development (AAFRD) as part of a province wide soil quality monitoring program of agricultural lands. This resource monitoring is a component of the Alberta Environmentally Sustainable Agriculture (AESA) program to identify and monitor the impact of agricultural production on soil and water resources.

Description

This report summarizes the state of knowledge of agricultural greenhouse gas (GHG) research and identifies preliminary gaps and sets out a science plan to contribute to efficient funding of GHG projects. It also provides the initial groundwork for a farm-level GHG assessment, to allow producers to identify future changes they can make to reduce GHG emissions and provide producers a better idea of their GHG management options.

The micronutrient and trace element status of crops grown on the Alberta soil quality benchmark sites

Description

Crop micronutrient concentrations of both vegetative tissues and grain, if applicable, were measured from 17 selected AESA soil quality benchmark sites in the fall of 2003. Micronutrients analyzed... More ≫

Description

Crop micronutrient concentrations of both vegetative tissues and grain, if applicable, were measured from 17 selected AESA soil quality benchmark sites in the fall of 2003. Micronutrients analyzed included boron, cadmium, chlorine, copper, iron, manganese, molybdenum, nickel, selenium, silicon and zinc. The purpose of this report is to provide an account of these micronutrient concentrations and to correlate them with a number of selected soil properties including soil pH, organic carbon, sand, silt and clay content, cation exchange capacity and calcium carbonate concentrations. In addition, the uptake, translocation and importance of each micronutrient are discussed, as is a summary of the effect of micronutrient partitioning between the grain and straw fraction, the effect of landscape form and the effect of provincial ecoregion on their concentration.

Description

Reports on the results of a series of focus groups with farmers held by Alberta Agriculture, Food and Rural Development to examine whether global climate patterns and more extreme weather events across the Canadian landscape were concerning producers. Discussions focused on the producers' risks, opportunities, and capabilities due to climate change. Also discussed were their views on what support they need in the management of risks associated with climate change.

Assessing the carbon content of the AESA benchmark sites from 1998 to 2004

Description

The Alberta Environmentally Sustainable Agriculture Program (AESA) Soil Quality Resource Monitoring Program has provided a data set containing soil organic carbon (OC) values and associated characteristics. These have been used to assess both the total amount, and changes in soil OC at these sites. The program consists of 42 sites distributed throughout the province and covering the major agricultural regions. Each site is intended to represent the ecodistrict where it is located. At each site, upper, mid and lower slope positions were sampled to evaluate the influence of topography on soil. The sites have been monitored since 1998. This monitoring included yield measurements and annual analysis of surface soil. These soil test results, combined with the total soil profile data from an initial pedological investigation, provide a unique opportunity to examine soil OC under a broad range of soils, climate and management practices.

Description

This report describes the micronutrient and trace element status of the AESA (Alberta Environmentally Sustainable Agriculture) Soil Quality Benchmark Sites. This study includes forty-three benchmark sites distributed across the agricultural regions of Alberta. The sites are located in seven ecoregions, namely: Peace Lowlands (PL); Mixed Boreal Upland (MB); Boreal Transition (BT); Aspen Parkland (AP); Moist Mixed Grassland (MM); Fescue Grassland (FG) and Mixed Grassland (MG).

Description

Soil quality can be briefly defined as how well a soil is able to function within an ecosystem. One way to assess soil quality is to use a quantitative method such as the United States Department of Agriculture-Agricultural Research Service (USDA-ARS) Soil Quality Test Kit. The kit measures various biological, physical, and chemical indicators but does not include a test for determining soil organic matter. The objectives of this study were to test two field methods for determining soil organic matter using soils from 41 sites across Alberta and to compare to measured soil organic matter and light fraction carbon obtained through conventional laboratory analyses.

Description

A literature review for the Alberta Environmentally Sustainable Agriculture (AESA) Soil Quality Monitoring Program was initiated within the Conservation and Development Branch of Alberta Agriculture, Food and Rural Development (AAFRD), with the intent to synthesize current literature on soil quality indices. This review has included coverage of publications dealing with the various approaches used in developing soil quality indices. It will assess the literature, by March 2004, for indices appropriate to western Canadian conditions and with respect to the needs of the AESA Soil Quality Program.
