The two-stage roller/crimper has proven to be as effective as the original straight-bar roller. As part of the investigation, they compared "Big Crimpin" with the "Burndown" tactic. Because cover crop termination has to occur later with roller-crimping, growers may need to plant cash crops into the cover crop before rolling or select a shorter-season cover crop species so it will reach maturity earlier, Silva says. Hairy vetch is a legume capable of producing 3 tons of dry matter biomass and providing 180 lb/ac of nitrogen to the following cash crop. I did walk the edges to termitate some velvetleaf, lambsquarters, pigweed and waterhemp. No-tiller Steve Groff's biggest challenge with roller-crimping is cover crop lodging, where the stems lie in different directions, making planting more difficult. While burn-down herbicides are common, there are non-chemical alternatives for offing cover crops that are compatible with no-till production. Let's start with the example of the rolling stalk chopper. Combining an effective herbicide with a roller crimper could offer the benefits of earlier and excellent cover crop control along with weed suppression. Groff and Silva encourage no-tillers to start small — preferably no more than 10-20 acres in the beginning, Silva says.
The roller/crimper is the tool that makes organic no-till possible because it does just that. The implement is rear mounted on a tractor. Shielding the bearings is crucial to successfully rolling thick dense cover crops. Firm soil also prevents the cover crop from being pushed into the soil. While roller-crimpers are simple to use, ensuring an effective cover crop kill with them is a little more complicated. Groff notes that lodging isn't as much of a concern with succulent legumes like crimson clover and hairy vetch because they're much easier to cut through than a species like cereal rye or triticale. The RC has made using cover crop residue to suppress weeds in NT operations more practical for organic farmers. Although they were designed for other functions, they appeared to adapt well to managing cover crops. If possible, I would recommend trying this on fields with minimal weed pressure, possibly after a cover crop that suppresses weeds like buckwheat.
