With many of Nebraska’s acres in cover crop mixtures due to prevented planting, it's important to make a quick check of your acres after a freeze and before grazing or feeding as some plants may be hazardous if fed incorrectly.
With extended wet conditions this season, every precipitation event going forward has the potential to bring harvest activity to a grinding halt. The big question is how extensive will the delays be. Climatologist Al Dutcher offers good and bad news for some.
Climatologist Al Dutcher looks at freeze risks for various sites, maturities and planting dates for corn. In some areas slightly warmer-than-normal August temperatures reduced freeze risk while in others, conditions were cooler than normal.
Table 1. The odds (%) of an early fall hard freeze (28°F or less), calculated using 2019 GDD accumulations from emergence to August 31 and applying 1981-2010 GDD accumulations from September 1 to the average first hard freeze date. The table (stacked in two parts) shows the odds for four emergence dates.
