Assessing Cover Crop Biomass Using Aerial Imagery: Lessons Learned During the UNL-NRCS Soil Health Initiative

October 15, 2020
Using aerial imagery, a non-destructive and easy-to apply method, we are able to gain insight into cover crop biomass production across an entire field, which would not be possible with traditional, boots-on-the-ground biomass sampling.

Seeding Rates for Broadcasting Cover Crops Into Late-season Corn and Soybean

September 17, 2020
The middle to end of September is a good time to establish cover crops by broadcasting seeds into corn or soybean before harvest. Broadcast interseeding before harvest allows cover crops to capture more sunshine, growing degree days and rainfall than drilling after harvest.

How Much Nitrogen Does My Cover Crop Take Up and When Do I Get It Back?

August 27, 2020
Biomass production, N uptake, and C:N ratio vary widely across the United States. The N in cover crop biomass will be released within a few weeks after termination, however, decomposition varies with soil moisture, soil temperature and C:N ratios.
