Managing alfalfa fields now is important later.

Fall is a good time for alfalfa growers to review their fertilizer and weed management options. David Miller, Pioneer alfalfa research director, says potash levels are key to a good crop next year.  Miller says an application in the fall or spring is fine. Typically, the best time is after the third or fourth cutting, depending on yield levels during summer months, to help maintain conditions for winter survival.

Also, the fall months are a good time for producers to work on weed management. Miller says that autumn is an optimal time to control perennial weeds. It's smart to kill weeds before they establish. He says the majority of the time, a great spring alfalfa stand is due to applying weed control measures in the fall or early spring while the alfalfa is still dormant.
