| here is a link to a new report describing a 2 year study on 2 IA farms evaluating cereal rye termination date ahead of soybeans.

Study overview:
Delaying cover crop termination until near soybean planting would allow for more biomass production by the cover crop in the spring presenting the opportunity for more environmental benefit. Two farmer-cooperators continued work they began in 2015 that compares terminating a cereal rye cover crop 2-3 weeks prior to seeding soybeans (early termination) with terminating the cover crop within 5 days of seeding soybeans (late termination).
Key findings:
Jeremy Gustafson saw a 2 bu/ac increase and improved weed control with the late termination treatment in 2016. This amounted to a $49.97/ac economic benefit compared to the early termination treatment. In 2015, soybean yields were equivalent between the two
termination date treatments.
Jack Boyer saw no difference in soybean yields between the two cover crop termination treatments in either year. In 2015, he was able to skip a post-emergence herbicide application which saved him approx. $40/ac
