Abstract

Soils representing the more important series on Prince Edward Island (P.E.I.) and forage and cereal crops grown on them were analyzed for Se content. Total soil Se content varied from 0.09 to 0.60 ppm and showed a positive significant correlation with the Se content of timothy (r = 0.40) and with soil pH (r = 0.29). The Se concentration of forage crop tissues and cereal grains from P.E.I. varied from 0.004 to 0.043 ppm. These concentrations of Se are considered to be deficiency levels for livestock feed. Wheat kernels contained a higher concentration of Se than barley kernels; however, barley tissue, sampled at the boot stage, contained higher quantities of Se than wheat sampled at the same stage. Addition of lime, S, B and Mo to the soil, under field conditions, did not affect the Se concentration of plant tissues.
