They are a major enemy to crops as they bring competition of nutrients. Crop rotation thus reduces the population of weed or, better yet, denies them an opportunity to grow. This, in the long-run, allows the farmer not to use tillage on the ground as it is a harmful technique of weed management to the soil structure.
