Abstract
A study was conducted to evaluate the relationship between nutrient content in wheat grain in
relation to the soil test availability of nutrients from soils where the wheat was grown. Grain
samples of ten genotypes of spring wheat (five bread wheat, three Durum and two utility) were
grown at six different sites (near Vulcan, Delia and Three Hills in Alberta, and Watrous, Regina
and Moose Jaw in Saskatchewan). The harvested wheat grain was analyzed for mineral nutrient
content, and soil samples were taken from the six field sites prior to planting, and analyzed for
plant available nutrients. Some nutrients showed a significant correlation between grain mineral
content and soil test availability. Other nutrients showed little correlation between the two
measurements. It is thought that some nutrients are actively maintained within a general range of
concentration in grain of wheat, while other nutrients are subject to additional uptake and
translocation into wheat grain when abundant nutrient levels are available in the soil.
