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.
A benefit of legumes is that they can mine nitrogen, phosphorus, and potash from the subsoil. Frame said a goal of the research is to discover if those nutrients from the cover crop can be used by the cash crop following the cover crop.
Getting the greatest benefit out of cover crops requires a management level on par with corn and soybeans. Growers should start by testing a cover crop on a single field and expand.
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.
An important aspect of raising cover crops is terminating them. Growers have options when it comes to terminating covers, and factors such as cost, location, and weather come into play as well.
