Phosphorous is notorious for binding in the soil and, thus, being unavailable to plants. This in turn leads to either phosphorus deficiency or over application of phosphorus fertilizers. MegaPhos SP is a high concentration of a select bacterial strain that aids in transformation of soil phosphorus into an assumable form for plants. The active ingredient in MegaPhos SP, Bacillus megaterium HM87, produces enzymes and other secondary metabolites that solubilize and mineralize normally unavailable phosphorous. MegaPhos can be used as a drench, liquid feed, irrigation, spray or seed treatment. OMRI Listed for organic production.
