Broadcast Interseeding with a Highboy — What We Learned in Year One
December 16, 2022
First-year results of a study to assess cover crop establishment using broadcast late-season interseeding in rainfed and irrigated fields.
Highboy Cover Crop Interseeding Project
October 6, 2022
Interested producers are encouraged to participate in this new UNL project, wherein researchers are interseeding cover crops into late-season corn to provide additional growth time before winter dormancy.
How Much Nitrogen Does My Cover Crop Take Up and When Do I Get It Back?
September 9, 2022
An evaluation on the range of biomass production of cover crops, the amount of nitrogen in their biomass, and their C:N ratio to help inform nutrient changes following cover crops.
Comparing Cover Crop Planting Methods
September 1, 2022
While planting cover crops after harvest with a drill or planter may be the most convenient, there are several other planting methods that can increase cover crop success as measured by biomass production.
Seeding Rates for Broadcasting Cover Crops Into Late-season Corn and Soybean
August 31, 2022
The middle to end of September is a good time to establish cover crops by broadcasting seeds into corn or soybean before harvest, which allows the crop to capture more sunshine, growing degree days and rainfall.
Cover Crop Biomass Calculator Available for Nebraska
July 7, 2022
This new tool estimates cover crop growth with different planting and termination times across the state of Nebraska, to help producers maximize cover crop growth between fall harvest and spring planting.
Expanding the Integrated Weed Management Toolbox: Winter Cover Crop Impacts on Weed Dynamics in Eastern and Central Nebraska
April 4, 2022
Results of a 2021 UNL study to determine cover crop impacts on weed suppression through analysis of the soil seedbank.
Illustrating Important Growth Stages for Winter Cereal Cover Crops
December 2, 2021
Knowledge about plant growth stages is important for management decisions and to predict how well a plant may cope with stress, such as low temperature.
