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

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).
