Hardwood trees and shrubs have the ability to grow much faster than conifers. Booster Paks were formulated in a 30-gram biodegradable format based on a research collaboration between the RTI and the USFS "Below Ground" research team at the USFS Research Station, Athens, GA.

The formulation was designed to be low in nitrogen, high in phosphorous, and to include both cobalt and molybdenum which increases the activity of the "Frankia" bacteria when present in the soil.
