Beneficial effects of dog fur as a potting soil component

Commercial potting soil mixes are typically dominated by peat moss, a nonrenewable resource. Here, we explore the potential of a novel alternative growth medium: dog fur waste collected from retail grooming salons. We evaluated three common container-grown crops (basil, lettuce, and marigold) and found that all three exhibited substantially improved growth when a standard potting mix was amended with dog fur (25% or 50% by volume). These surprising effects encompassed multiple response variables, including both vegetative and reproductive structures. Our results suggest that dog fur has potential for a wide range of applications spanning both edible and ornamental plant production.
