Research Shows Extra Cover Crop Growth Prior to Soybeans Provides Benefits

March 7, 2016

ICM News: The research showed winter cereal rye that grew an extra three weeks prior to soybeans produced about 300-400% more biomass (Fig. 1) with a 100% increase in nitrogen retention (Fig. 2), when compared with early terminated cover crops. Results from this study showed no difference in soybean yield following a cover crop killed three weeks prior to soybean planting compared to a cover crop that was killed one day before soybean planting.
