Understanding Ideal Timing of Roller Crimping Cereal Rye Cover Crops

By Emma Link posted on July 8, 2024 | Posted in Termination

Determining when and how best to use roller-crimpers has been a subject of interest in the Cooperators’ Program from Practical Farmers of Iowa (PFI) for the past seven years. In 2023, five cooperators conducted on-farm research on roll-crimping a cereal rye cover crop ahead of soybeans. Here are the findings on ideal timing of roller crimping a cereal rye cover crop.

While later cover crop termination in the spring can allow for more biomass accumulation, such later termination can change the C-to-N composition of the plants impacting residue decomposition. Therefore, identifying the best time for cover crop termination to provide optimal N cycling benefits can help farmers make decisions about cover crop management.
