Interns Share University Crop Research Results


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 to conservation practices.

Using High-Carbon Char as a Soil Amendment to Improve Soil Properties


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.

Can a Rye Cover Crop Reduce Wind Erosion from Fields with Little Residue Cover?


That was the question researchers studied at two eastern Nebraska sites. While the cover crop didn't appear to directly reduce wind erosion potential, it could still reduce erosion by covering the soil and minimizing soil aggregate degradation.

Does Seeding Rate Affect Establishment-Year Growth and Long-term Forage Yield of Indiangrass?


Recent improvements in forage yield and nutritive value of indiangrass, along with its wide range of adaptation, should increase its use in bioenergy and forage production, conservation practices, and reclamation projects in the central Great Plains. This study tested five seeding rates with two varieties — 'Oto' and 'NE 54' — and the effects on dry matter production.

Does Weed Control Method Impact Indiangrass Establishment and Persistence?


This study evaluated two weed control methods and seeding rates on establishment and persistence of two indiangrass cultivars, 'Oto' and ‘NE 54’, from 2003 to 2007.



switchgrass barrier

Switchgrass Barriers as a Soil Water Conservation Practice


Research was conducted to compare infiltration rates in switchgrass barriers and a soybean field. Results showed the value of grass barriers in improving soil structure and infiltration and reducing runoff of sediments and nutrients.



Corn in cover crop research

Rain-Fed Corn Growth and Development Following Cover Crops in 2017


Researchers in south central Nebraska examined potential effects of planting rye and a rye-mix cover crop following wheat and prior to corn in rain-fed conditions. Based on their findings, they offer two take-home messages for cover crop growers.



Graph of CO2 fluxes by tillage

Long-term Tillage and Soil CO2 Fluxes


How do different tillage systems and the timing of tillage affect CO2 and what factors contribute to fluxes? These were the questions addressed by researchers studying long-term tillage and no-till plots in eastern Nebraska.
