- Final 2012 Predictions of Dryland and Irrigated Corn Yield Potential. Based on Hybrid-Maize Model simulations, yield potential for four irrigated sites in Nebraska are 3-8% below the long-term potential. The story for dryland production is much different, ranging from 32% to 67% below long-term average yields.
- Diminished Corn Production and Ethanol Policy — Should the RFS be Waived? In this week's Cornhusker Economics UNL agricultural economist Richard Perrin looks at potential impacts from changes to the Renewable Fuels Standard (RFS).
- Alternaria Leaf Spot of Soybean. This fungal disease, which is favored by drought conditions, has been confirmed in soybeans in Webster County. Early detection is important and prevention starts with fungicide-treated seed.
Harvest & Storage
- Managing Large Grain Bins for Potential Mycotoxin Contamination. Minimum airflows of at least 1.25 cfm are recommended when molds and mycotoxins are suspected. This can be a challenge in today's large grain bins. See how using different fans affects airflow and recommended grain depth.
- How to Estimate How Much Grain is in a Bin. With the right equations, it's easy to calculate for round bins, peaked grain, and rectangular storage buildings.
- Diversification and Sustainable Practices May Offer Long-term Gain after Drought. With drought conditions persisting, this may be a good time to diversify your cropping plan and implement long-term sustainable practices.
- After the Drought: Sept. 27 Webinar on Available Mental/Behavioral Health Resources. As disappointing harvests and livestock herd reductions become a reality for many, the financial and emotional impacts of the drought may lead to crisis in some farm families. A Sept. 27 webinar will provide information and identify resources available to aid recovery.

- Nebraska Corn Harvest Predicted to be Lowest Since 2006, according to a USDA harvest report released this week. The national corn harvest is predicted to fall 13% below 2011. Yields are expected to average 122.8 bu/ac, the lowest since 1995. The soybean and sorghum harvest is expected to be the lowest since 2002. Sugarbeet yield is expected to set a record high.
