2018 Corn Yield Forecasts: Approach and Interpretation of Results June 29, 2018

Here's how the Yield Forecasting Center will be developing corn yield forecasts for 41 locations across the Corn Belt during the 2018 crop season. Modeling, using Hybrid-Maize, weather data, and on-site verification help researchers estimate yields so growers can adjust management during the season, if necessary.

Crop Residue and High-Carbon Char: Potential Soil Conservation Tools May 8, 2018

Soil is the single most important resource on which our agriculture depends. Proper soil management is necessary to sustain long-term agricultural productivity. Soil loss through erosion or run-off hurts agricultural production with depletion of organic matter and fertility. It also has environmental implications.

Feasibility of Sensor-Based Nitrogen Fertigation Management in Corn May 7, 2018

Averaged across two years, the sensor-based N fertigation treatment consistently resulted in higher profit and nitrogen use efficiency. The use of fertigation offers the unique capability to minimize N losses by reacting to slight N deficiencies in corn by applying N multiple times throughout the season with lower application rates.

Nebraska Soybean N Trials
Figure 1. Photos of one site of the Nebraska Extension Soybean Management Field Day research (2013) that compared the effects of several nitrogen treatments on soybeans. Pictured is the zero N control on the left and the 400 lbs/ac split N application on the right. Averaged over four sites the control yielded 73.4 bu/ac and the 400 lbs N averaged 78.9 bu/ac.
