Fifteen sites across the US are carrying out a cover crop field trial to evaluate cover crop weed management when terminating it either six, four or two weeks prior to planting soybeans. Cover crops for this purpose need to develop high biomass and high lignin content. Terminating a cereal rye cover crop two weeks prior to planting reduced Palmer Amaranth emergence in more than 50%. Dr. Jason Norsworthy shows his results at Fayetteville Research Station, AR.
