Late planted oats forage
Late planted oats = forage grew!

  • Plant after the equinox, up til early September

  • Plant 64 to 120 pounds

  • Plant the cheapest oats you can find

  • No-til, lightly til, broadcast

  • Fertilize?

  • Multiple grazings and/or harvests?


Let s look at the costs
Let’s look at the costs grew!

  • 100 pounds of oats @ .16 = $16

  • Planting

    • No-till, $15 / acre

    • Aerial seeding, $10 - $13

  • Fertilizer, ~ 40 units of N @ 60 cents

  • P & K removal = 14 lbs P (.55), 50 lbs K(.40)

  • P & K removal for oats are essentially the same as for any hay crop.

  • Total costs = < $55/acre + $27.70/T (P&K)

  • Yield = 0.5 to 5 ton/ac of HIGH QUALITY feed!

  • Oats can supply quality livestock feed at a reasonable cost throughout the fall and winter.

  • Dry matter amount doubles between 4 weeks and 6 weeks.

  • Oats can be harvested many ways.

  • July planted oats have smaller leaves than August planted oats.

  • Quality does not change much after frosted.

  • Differences from year to year in yields and quality are mostly weather related.
