2021 Corn Yield Forecasts as of Aug. 25

August 25, 2021
In line with previous forecasts in mid-July and early August, there is no indication that this is going to be a record — and not even an above average — year for national corn yield.

2021 Corn Yield Forecasts as of July 14

July 14, 2021
Although it is still too early to make strong inferences about end-of-season yields for irrigated corn, there is a relatively high probability for near-average yields for a majority of sites.

Anticipated high residual soil nitrate-N levels in NE rainfed crops of dry 2020 can be credited to reduce N rates for 2021

Planning 2021 Fertilizer-N Application Following a Dry 2020

October 6, 2020
Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?
