Other claims from this paper (12)
- Observation Saskatchewan grain calcium and potassium were below published values.
- Observation Saskatchewan grain zinc and iron were above published values.
- Observation Selenium averaged 0.25 ppm in each grain and was below literature values.
- Observation Selenium and copper levels varied strongly.
- Observation Other minerals had coefficients of variation from 9 to 35%.
- Association Season, soil zone, soil type and cultivar significantly affected calcium, phosphorus, magnesium and potassium composition in most grains.
- Association Soil type had little effect on zinc, copper, manganese and iron composition.
- Association Few cultivars differed significantly in zinc, copper, manganese and iron composition.
- Observation Grains from Gray soil locations were high in zinc and low in manganese.
- Observation Grain selenium was highest in the Brown soil zone at 0.39–0.55 ppm.
- Association Grain selenium declined through Dark Brown and Black soils to 0.06–0.07 ppm in Gray soils.
- Association Clay soils were associated with higher grain selenium than loam soils in each grain.
