49. Planting Cover Crops with a Highboy Interseeder

Cover crops are a useful tool for improving soil health and water quality, but can be challenging to plant. In Nebraska, cover crops are often planted after harvest, but it leaves little time for cover crops to establish before winter conditions set in. Interseeding cover crops in late season corn is one possible method of increasing cover crop success. In this episode, we hear from several guests about a unique interseeding project the University of Nebraska-Lincoln is conducting in partnership with several Natural Resources Districts (NRDs) and the Nebraska Department of Environment and Energy (NDEE).

48. Scheduling the Final Irrigation of the Season

Knowing when to stop irrigating and how much to apply is one of the last and most challenging decisions of the growing season. In this episode, Bruno Lena, an extension educator for Platte, Boone, and Nance counties, explains the three main factors that go into accurately calculating the final irrigation for corn and soybeans.

47. Using Drought-Stressed Corn as Livestock Feed

Corn in much of the state has been impacted by drought conditions this summer. In some cases, it may make sense to utilize this corn as a source of animal feed rather than harvest for grain. However, this is not without risk, primarily in regards to animal health. In this episode of the Nebraska CropWatch Podcast, Brad Schick, a Beef Systems Extension Educator with the University of Nebraska-Lincoln, provides information on considerations for using corn as animal feed. This includes when and how to harvest, concerns around high nitrate levels, and how to best manage corn harvested for animal feed if this is the case.
