Nutra-Sorb K-Prime 0-0-25 is a new type of liquid potassium that has significant advantages and benefits over other foliar applied potassium sources. Unlike other liquid potassium sources such as nitrates, hydroxides, thiosulfates or carbonates, K-PRIME has a near neutral pH and is not caustic or corrosive, resulting in safer foliar applications and less stress on the plant. Plants absorb potassium from K-PRIME in much higher proportions than from all other sources, including nitrates and sulfates. K-PRIME is actually a hybrid of an inorganic salt and an organic acid, making it a truly unique foliar fertilizer.
