Livestock producers are encouraged to regularly assess their forage inventories. This year there are several indicators that point to localized or even statewide hay deficits.
The early summer USDA crop acreage estimates indicate that 2007 alfalfa, mixed alfalfa and grass, and "other hay" acreage is down 8 to 9 percent from that of a year ago. Higher grain prices and the early-season freeze have contributed to this decreased acreage. In addition, the early April freeze led to 20 to 50 percent lower first-cutting yields across much of the state. Potato leaf-hopper populations are high already and may contribute further to reduced summer production in alfalfa-based hay fields.
Some ways to possibly make up some of the deficits could be considered:
- Some producers will be harvesting oat or other cereal grain crops for hay and silage to make up some of their deficits.
- Producers with alfalfa-based hay fields are encouraged to scout for and manage potato leafhopper populations for the remainder of the summer, to maximize the yield potential of their summer harvests.
- There are still a couple weeks to consider planting a warm-season, annual grass crop for "emergency forage." While there is still time to produce a productive crop before fall frost, there is a risk that there will be insufficient soil moisture and timely rainfall to establish and produce a productive crop over the next few months.
- There may be an opportunity to harvest hay from CRP acres.
- Corn silage or soybeans harvested during early pod fill also are possible but often less viable forage choices.
