Spectrum™ - Soil Inoculant
Spectrum™ contains a multiple species blend of plant growth promoting rhizobacteria (PGPR) and other beneficial plant growth promoting microorganisms (PGPs). The beneficial soil-based microorganisms in Spectrum™ break down and release vital nutrients (such as phosphorus, nitrogen, calcium, iron, and more) stored in soil particles, making the nutrients more readily available to the plants in forms they can absorb.
Spectrum DS™ (formerly Spectrum Extra™) is designed for use in drought-stressed, high salinity soils. Blended with an emphasis on drought and salt tolerant microorganisms, Spectrum DS can help mitigate these damaging effects and allow crops to thrive in harsh environments.
Spectrum PSB is a formulation that includes phosphorus solubilizing bacteria (PSB). Phosphorus that is present in the soil tends to dissipate quickly by leaching into water, becoming biologically bound in organic forms, or forming insoluble complexes which the plant cannot process. The phosphorus solubilizing bacteria (PSB) found in Spectrum PSB break down these bound or insoluble forms of phosphorus, making them available for use by the plant.
