Forage Crop
Southern crabgrass, and the related large crabgrass, especially the cultivars 'Red River Crabgrass', 'Impact', and 'Quick-n-Big', have been utilized as a forage crop for livestock, as it is a highly nutritious warm season grass. Red river crabgrass responds well to nitrogen fertilizer, growing up to 3 feet tall, and needs to be in rotation with cool-season forage.
