Abstract
Cover crop mixtures seeded after winter wheat in August had
much greater biomass in late fall compared with cover crops
inter-seeded in corn in late June.
• Competition for light and soil moisture reduced cover crop
establishment and growth in corn and resulted in absence of
the expected depression>slope~summit biomass gradient,
with the exception of tillage radish in the WK treatment.
• Cover crop mixtures planted after winter wheat provided good
weed suppression.
• In drier summer environments (as in Ukraine), inter-seeding of
WH and WK cover crops in corn reduced yield in the
topographical depressions.
