Crop roller “crimping” has become a common way to mechanically terminate annual cover crops. Crimpers are used to kill grass cover crops (cereal rye, barley, wheat, sorghum, Sudan, millet), vetches, annual clovers, buckwheat, and multi-species cover crops.
Crimpers knock down cover crops, crimping the stems in several places, stopping the sap flow and forming a mulch matt to suffocate weeds. The following crop can then be planted directly into the crimped cover crop.
Rolling flattens the cover down to form a mulch layer. The crimping does not cut the cover crop stems, but stops the flow of water from the roots to the shoots and the flow of sugars from the shoots to the roots by crimping their vascular system.
