Corn Residue Removal and CO2 Emissions February 26, 2018

University research looking at CO2 emissions from two types of residue removal (baling and grazing) compared with a control treatment found little day-to-day impact; however, when looking at cumulative data for the whole year, grazing did appear to affect cumulative CO2 emissions in irrigated crop-livestock systems. This data represents the first year of this study.

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.

Perceptions of Crop Consultants and Crop Producers on Grazing Corn Residue in Nebraska October 19, 2017

A new journal article by University of Nebraska-Lincoln researchers reports on the results of a survey asking consultants and growers about what factors influence their thinking on grazing crop residue. The report notes that while corn residue grazing is a longstanding practice in the state, currently only about 25% of the state's corn residue is being grazed.
