Seeding winter annual small grain offers fall grazing for beef cow herds short on grass and hay.

Craig Roberts, University of Missouri Extension forage specialist, is receiving a lot of calls this summer on seeding small grains to replace dry pastures after interest grew for the drought disaster assistance being offered by USDA Farm Service Agency. He offers encouraging words, and cautions, too.

Not all grains work
Drilling wheat, cereal rye or oats can provide forage. Seeded in the fall, the grain crops become annual grass pasture for fall and winter. They supply quick grazing when fall rains return. Wheat and rye also provide more forage early next spring. Annual grasses give short-term gain but could start long-term pasture renovation.

Thickly seeded grain crops can kill weak existing forages. “If you have a good stand of fescue or alfalfa, don’t drill grain seedings on that land. Annual grain crops should be seeded only on weak pastures,” Roberts says. “There should be plenty of those this year.”

Rob Kallenbach, MU forage specialist, cautions that he has seeded winter grains into strong stands of fescue in his research. “All failed,” he says. “Fescue sod makes strong competition.”

Farmers should use caution seeding into an alfalfa field. “The cost of getting alfalfa seeded must be protected. Seed only into weak alfalfa stands that need renovation,” Roberts says.

Stockpile suggestions
Cereal rye remains winter-hardy, with quick regrowth next spring. The weaker oats give good fall growth but fade over winter. That leaves land open in spring for planting crops or seeding pastures.

This year needs extra attention to stockpiling fescue pastures for winter grazing, according to specialists.

“If there was ever a year to apply fall nitrogen, this is it,” says John Lory, MU Extension soil specialist. “You’ll get a big bang for your buck.” High-price hay makes grazing forage a cost-cutter.

Fall pasture care includes clipping stemmy fescue seed heads to encourage regrowth. In normal years, this includes grazing down to 3 inches. However, in drought areas, most grass leaves are already too short.

Winter pasture stockpile needs 40 to 50 pounds of nitrogen fertilizer per acre. This should go on by mid-August, before fall rains. Most years those rains start Sept. 1.

Fall-applied nitrogen won’t be wasted if rains don’t come. Fertilizer will still be there for spring growth. Usually, spring nitrogen isn’t needed. If it doesn’t rain, spring forage becomes worth even more.

“All plans for fall grass growth depend on return of rains.” Roberts says. “Just assume rains will come. They usually do.”

Farmers recall the drought of 2012. An extreme summer drought that year broke when big rains came the first week of September. Remnants of a Gulf Coast hurricane soaked much of the state. That rain restored grasses and made a soybean crop. Droughts do end.
