Spectrum Inoculant
Spectrum Inoculant
Spectrum Soil amendment contains a multiple species blend of plant growth promoting rhizobacteria (PGPR) and other beneficial plant growth promoting microorganisms (PGPs). This specially formulated soil inoculant enhances and restores beneficial soil microbe populations to augment the natural organic processes that occur in healthy soils. This product is OMRI approved for organic production.
For high-value crops, this product is best used for pre-plant inoculation or fertigation/soil drench. The following are maximum one-time application rates. If budget-constrained, I suggest cutting the application rates and applying more frequently throughout the season.
Fertigation/Soil Drench
Mix 1 tsp. to 1 Tbsp per gallon of water.
Apply every 7-10 days through drip irrigation or apply 8 oz. per plant around the root zone for 6” pots, 32 oz. per 5 gallon pot, 64 oz. per 10 gallon pot, etc.
Pre-Plant Propagation Inoculation and Starter Program
Mix 1 tsp. to 1 Tbsp in 10 gallons of water to soak plugs or soil prior to propagation.
Lightly mist new seedlings with a mixture of 1 oz. Spectrum per gallon of water in conjunction with trace minerals.
Repeat weekly after plants are 12-15” high and have at least three full sets of leaves.
