Handy Bt Trait Table Updated for 2018 Corn

January 31, 2018

The Handy Bt Trait Table, which lists the types of Bt hybrids present for all commercialized corn, has been updated for 2018. Now in its 15th year, the table has become the standard authoritative reference to Bt toxins in corn.

Improve Your Grain Marketing at Winter Workshops

January 26, 2018

Learn how to protect your farm operation from adverse market movements at one of the Nebraska Extension Grain Marketing Workshops being held this winter. The sessions are designed to help grain producers minimize losses during this time of low grain prices.

Nebraska Cover Crop Conference Feb. 15 for Corn, Soybean Growers

January 26, 2018

Cover crops offer many benefits, such as improved soil heath and reduced erosion. The challenges lie in the details, including what cover crops to use and how to use them. The Feb. 15 Nebraska Cover Crop Conference tackles these topics for growers using a corn/soybean rotation.

Innovative Youth Corn Challenge Tests Range of Practices

January 22, 2018

Winners of the 2017 Innovative Youth Corn Challenge were recently recognized at the annual banquet. Through the contest, youth groups theorize the effect of changing a corn production practice and then test it, using science-based research methods.

Stalk Lodging, Cover Crops Among Topics at Fremont Corn Expo Jan 4

December 15, 2017

The 2018 Fremont Corn Expo will take a closer look at key issues for Nebraska corn farmers, including stalk lodging, cover crops, market analysis, the weather outlook for 2018, and new grain bin technology. The event will be Jan. 4 at the Christensen Field in Fremont.

Figure 1. Based corn stalk residue. — Figure 1. Where moisture is not limited, research shows that removing some corn residue from a field may benefit yield in the following crop. However, if residue is removed for more than three years, research showed longer term impacts to the soil.

Crop Residue Removal: Impacts on Yield

December 8, 2017

A review of multiple research studies indicates that where moisture is not limited, residue removal can result in no yield reduction to yield increases for the subsequent crop. However, long-term residue removal has been shown to affect other production factors and it's recommended that even in minimal erosion areas, removing residue does impact other production factors and it's recommended that 2.4 tons/acre of residue be left in the field.

Amelioration Strategies after Corn Residue Removal

December 7, 2017

The authors review three research studies on how amelioration practices such as adding cover crops and/or manure may offset any effects of removing crop residue.

Corn Stover Removal: Nutrient Value of Stover and Impacts on Soil Properties

December 7, 2017

Corn residue has a number of uses and thus its value as well as its impact on other systems may need to be estimated when evaluating post-harvest options. This article looks at how to estimate the nutrient value of the residue and potential impacts to the soil from removing the residue, based on Nebraska research.
