"One of the things we're trying to do with the rotation is to make it easier to manage weed competition. We don't mind some [weeds] because some – Actually you can have quite a few and they have very little impact on your crop. We don't need to have fields with just soybeans or just corn in it. A few weeds really don't hurt anything. They are also good indicators of your soils, whether you have certain types of soil problems whether it has compaction problems or nutrient problems. They can help you do that. Plus they're great nutrient recyclers, so they have value in helping you maintain that. So – But we're managing in looking at those things and then we're looking at cropping sequence to manage insect pressures at certain stages of crop growth. And by growing certain crops in certain sequences we can take advantage of their allelopathic effects [controlling one species by planting another], so that we know whether or not they may help suppress other types of weeds and make cultivation and management easier."
