This week’s podcast, sponsored by NewLeaf Symbiotics, features John Wallace, Assistant Professor, Weed Science, Penn State University. Wallace will discuss why interseeding might be better than fall cover crop establishment, cover crop establishment rates with interseeding, interseeding best management practices, and more.

In this video from Penn State University, learn more about interseeding cover crops into corn; results from a study done on interseeding in Pennsylvania, Maryland and New York; how to reduce the risks and costs of interseeding; and more.

In this video from Penn State University Extension, learn more about interseeding cover crops into cash crops such as corn. Find out about the machine they developed that does interseeding and fertilizer application at the same time.

In this video from Penn State University, find out what cover crop species make an effective mixture, why adding more cover crop species to a mixture means more functionality, challenges to using cover crop mixtures, and more.

Researchers in Penn State's College of Agricultural Sciences have developed an important component of a new system that corn growers can use to adjust nitrogen fertilizer applications based on site-specific measurements of cover crops and soil organic matter. The development is notable because while the wide use of cover crops in rotations with corn in the last decade has resulted in reductions in nutrient pollution and sedimentation, the introduction of cover crops has muddled growers' decision-making regarding how much nitrogen fertilizer to apply to meet their cash crop demands.

Penn State researchers, in a recent study, were surprised to learn that they could take the exact same number of seeds from the same plants, put them in agricultural fields across the Mid-Atlantic region and get profoundly different stands of cover crops a few months later. The study came to be known as “‘farm-tuning’ cover crop mixtures,” noted researcher Jason Kaye, professor of soil biogeochemistry, who added that the findings are significant because they show the need to customize cover crop mixes to achieve desired ecosystem services, depending on soil and climatic conditions.

Dealing with slugs can be a real nuisance for many growers. Dr. John Tooker, Penn State University, discusses how seed treatments influence predator populations in the field, how soybean yields respond when slugs are present in fields with both treated and untreated seed, why predator populations are important in your fields and more.

This video describes the basics of cover crops and how they can benefit growers and the environment. Find out why using cover crops is a soil best management practice, how covers help prevent soil erosion, how cover crops scavenge and hold nutrients and more.

Cover crop mixes, or cocktails, can do a lot, but can also be complex to put together.
