HarvestRx™ is a uniquely formulated foliar fertilizer used to maximize the availability of phosphorus and potassium in sod farm soil profiles. HarvestRx™ is uniquely designed to increase rooting, overall soil health, tensile strength and abiotic stress defense. When applied during re-establishment (vegetative/seeding) HarvestRx in most cases will increase root mass of the newly added plants while increasing stress defense mechanisms. When applied as directed prior to harvest, HarvestRx™ will in most cases decrease chlorosis and stress of the palletized harvested sod.
