Nitrogen Replacement Value of Red Clover

• Extending and diversifying a crop rotation to include a small grain presents farmers with the opportunity to also include a forage legume that could possibly reduce the need for synthetic N fertilizer. • Cooperator Tim Sieren grew corn in rotation following cereal rye frostseeded with red clover and corn in rotation following cereal rye […]

Rolling Cover Crops and Soybean Row-Width

Cover crops are gaining new attention for their ability to reduce weed pressure in soybeans. Specifically, when seeding soybeans directly into a thick cover crop. Farmer-cooperators Jack Boyer and Scott Shriver investigated the effect of row-width on soybean yields when rolling a cereal rye cover crop. Boyer rolled select strips after terminating with an herbicide; […]

No-till vs. Strip-till Corn and Soybeans Following a Cereal Rye Cover Crop

A successful management strategy for corn and soybeans following a cereal rye cover crop may differ across farms in terms of tillage, N fertilizer application or both. Farmer-cooperators Jack Boyer, Tim Sieren and Jeremy Gustafson compared no-till and strip-till when planting their corn or soybeans following a cereal rye cover crop.

Terminating Cereal Rye Cover Crops After Planting Soybeans

Planting soybeans within one day of terminating a cereal rye cover crop does not reduce yield and can improve weed control compared to terminating the cover crop 10–14 days prior to planting soybeans. In experimental trials, farmer-cooperators Jack Boyer and Tim Sieren compared two cereal rye cover crop termination dates: early (near the time of […]

Soybean Row-Width and Seeding Date When Using a Roller-Crimper for Cereal Rye Cover Crop

Waiting to plant organic, no-till soybean until terminating cereal rye by roller-crimping delays planting to late May. To try to plant soybeans earlier in roll-crimped cereal rye, Scott Shriver planted soybeans 17, 13 and zero days before roller-crimping and compared yields and stand counts. In a separate trial, Shriver compared soybean yields and stand counts […]

Cereal Rye Cover Crop for Reducing Herbicides in Soybeans, 2019

Based on previous on-farm research he has conducted,[1] Sam Bennett has seen evidence that a cereal rye cover crop can suppress weeds and reduce herbicide inputs in soybeans. As such, he grew soybeans following a cereal rye cover crop and compared three herbicide packages that varied in residual activity and cost. Bennett hypothesized that weed […]

Terminating Cereal Rye After Planting Soybeans

While maximizing the benefits of cover crops requires extending their growing period, prolonging growth and delaying termination beyond the date of soybean emergence is not allowed under federal crop insurance rules. Sam Bennett, Tim Sieren and Jon Bakehouse compared cereal rye biomass, soybean stand counts and soybean yield between strips in which a rye cover […]
