Oats may be one of our most under-used fall forages. That's right. Plain old dull oats. It grows fast, thrives under cool fall conditions, has good feed value, and can produce over 2 tons of hay or pasture yet this year. And it dies out over winter, protecting soil without causing planting problems next spring.

Planting Tips

  • To plant oats, drill about 3 bushels of oats per acre in early August for maximum yield potential. A fully prepared seedbed usually is best, but you can plant oats directly into wheat stubble or other crop residues if weeds are killed ahead of planting.
  • You might even fly-seed oats onto corn fields severely damaged by weather or ones which are to be chopped early for silage, although rye tends to work better for flying on seed.
  • Avoid fields with herbicide carryover and topdress 40 pounds of nitrogen per acre unless the previous crop was heavily fertilized.

With good moisture, oats will be ready to graze about six to eight weeks after emergence. Calves and yearlings can gain over two pounds per day, but be careful to avoid grass tetany on lush oat pasture. Ask your veterinarian if you should supplement with magnesium. Also, don't suddenly turn out on oat pasture if livestock have been grazing short or dry pastures. Sudden respiratory problems can occur.

For hay, cut soon after plants begin to dry out after a killing freeze, or cut earlier if plants reach a desirable growth stage. Oats can accumulate nitrates, so test hay before feeding.

If you have good soil moisture, fall oats may be a good option for your operation.
