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?

2020 Corn Yield Forecasts: End-of-season Forecasts Suggest Near-average Yields for the Region

September 17, 2020
Our forecasts suggest a near-average year for irrigated corn at most sites. For rainfed corn, the scenario is diverse across regions.

2020 Corn Yield Forecasts as of August 25

August 27, 2020
Compared with our previous forecasts, there is still a high probability of near-average yields for the majority of the irrigated sites. For rainfed corn, the scenario is diverse across regions.

2020 Corn Yield Forecasts as of July 14

July 16, 2020
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.

2020 Corn Yield Forecasts: Approach and Interpretation of Results

July 9, 2020
The Yield Forecasting Center (YFC) will provide real-time information on corn phenology and forecasts of corn yield potential every three weeks, starting in mid-July, to aid growers and ag industry in making management, logistics, and marketing decisions through the 2020 season.

Corn and Clouds: “…from both sides now…”

November 6, 2019
Solar radiation and temperature data for the third week of August in central Nebraska indicates it likely contributed to the lower-than-expected yields being reported by many growers this year.

Map showing probability of deviation from normal yields for rainfed sits in Nebraska and Kansas

2019 Corn Yield Forecasts as of September 17

September 19, 2019
Forecasted end-of-season yields for rainfed corn across the Corn Belt indicate above-average yield at two-thirds of the sites, with yields well above historical averages in Nebraska, Kansas, and Missouri. See data for individual irrigated and rainfed sites.
