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.

Interns Share Research Results from Field Studies and Extension Experience February 14, 2018

Seven Experiential Learning Fellows in a USDA-funded program at the University of Nebraska-Lincoln spent their summer 2017 working with scientists, reviewing and conducting research, and developing Extension education to convey research findings to growers for field application. This article describes the program and links to their articles on timely topics from cover crops to soil management.

High-C char residue after sugarbeet processing

Using High-Carbon Char as a Soil Amendment to Improve Soil Properties February 13, 2018

Can a residue from sugarbeet processing in western Nebraska be used to increase soil carbon? Researchers share the first year of data examining the effects on soil carbon and soil physical properties from using high-C char.
