The selenium content of corn grain produced in central New York was increased 670% by application of fly ash containing 6.5 ppM Se to soil at the rate of 500 tons/acre. Fat-extracted corn produced from untreated soil contained 0.038 ppM Se; corn produced from fly ash amended soil contained 0.296 ppM Se. The Se content of corn grain produced 1 year after soil amendment was comparable (0.306 ppM Se) to that of the first season crop, indicating the persistent effect of the soil treatment. Vitamin E deficient and Se-deficient chicks were fed vitamin-D free, Se-deficient semipurified diets cntaining incremental amounts of Na/sub 2/Se0/sub 3/ or fat-free ground corn produced from fly ash amended or control soil plots. Results showed that approximately 50% of the Se in fly-ash-soil corn was available to the chick for promoting growth and plasma Se-dependent glutathione peroxidase and for preventing the vitamin E-Se deficiency disease exudative diathesis.
