Corn yield and soil nitrogen following winter annual cover crops interseeded into soybean

Nitrogen demand for corn ( Zea mays L.) production is high, and winter annual cover crops (WCC) can be an alternative source of plant‐available N. Common corn–soybean [ Glycine max (L.) Merr.] rotations in the Mid‐Atlantic region leave fields fallow after soybean, providing a niche for WCC. The objective of this research was to evaluate the effect of rye ( Secale cereale L.), hairy vetch ( Vicia villosa Roth subsp. Villosa ), and rye–vetch...
