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.

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.
