If manure storages are nearing their limits, the risk of an overflow event becomes a pressing concern. Because overflow events can lead to serious environmental problems and potential regulatory fines, it's better to apply manure earlier than planned.
Ideally, ammonium-rich manures are applied when temperatures are cooler (50°F and cooling) to increase the probability that applied nitrogen will still be in the upper soil profile next year when crops are growing. However, sometimes applications earlier in the fall may be necessary, according to Daniel Andersen, with ISU's agricultural and biosystems engineering department.
