  • Patent number: 5360466
    Abstract: An organic, fresh-smelling fertilizer product is produced by collecting llama pellets from llamas that have preferably been fed only alfalfa hay with grain supplements. The pellets are first dried by means of a relatively slow process that enables them to harden as pellets rather than fragment, and they are then ground to produce a particulate mass such as powder, granulates or pellet-sized particles which has an alfalfa-like scent and is a very effective fertilizer.
