After a dry spring, many producers are asking the same question: how do we make up lost forage?
For a lot of operations this year, the answer is summer annuals.
Why summer annuals?
Summer annuals are fast-growing, high-quality forages that can help fill gaps when perennial systems fall short. In the Southeast, they’re typically planted from April through June and can be used for grazing, baleage, or hay.
Under good conditions, they can produce 5,000 to 10,000 pounds per acre with 15%+ crude protein—a strong option coming out of a poor spring. They are an excellent alternative to the increased risk of fescue toxicity across the summer months. Of course, that still depends on rainfall and management.
Even with risk, farmers are planting.
This isn’t a low-risk move.
Ongoing drought, elevated fuel and fertilizer prices make this a difficult decision. After looking at several extension enterprise budgets, some summer annuals could easily land in the $200/acre ballpark. However, doing nothing has a cost too!
Start with your goal.
Before planting, think about what you need most:
- Dry hay – Possible, but challenging due to thick stems. Higher seeding rates and a mower conditioner can help.
- Baleage – Strong option for hard-to-dry crops. Ensilation can also decrease nitrates
- Grazing – A great way to stretch forage, improve cattle performance, and give Fescue pastures a break heading into fall and punch through the summer slump.
Don’t overlook mixtures.
Mixtures are getting more attention—and for good reason.
Adding legumes can:
- Reduce nitrogen needs
- Maintain yield and quality
- Improve soil health and resilience
They can also help buffer against drought and extend the grazing season. Just keep in mind that herbicide options may be more limited.
A quick word on risk
Not all summer annuals handle stress the same.
- Pearl millet offers good drought tolerance and avoids prussic acid risk (though nitrates are still possible).
- Sorghum and sorghum-sudan can be high-yielding but require careful management due to prussic acid and nitrate concerns.
- Crabgrass performs well but needs consistent moisture
Final thoughts
Summer annuals aren’t a silver bullet—but they can help bridge the forage gap after a dry spring.
