Energy Relationships for Selected Cultural Investments
An energy balance was used to establish the minimum recoverable biomass needed to justify cultural investment energies for using forest biomass as a source of energy. The balance accounted for (1) energy inputs needed for production (control fertilization, irrigation, and fertilization/irrigation), harvesting, processing, and transportation, and (2) conversion efficiencies for converting the biomass into usable heat, process steam, or electricity. Total energy inputs for each amendment included energy values for amendment manufacturing, amendment application, biomass harvesting, biomass processing, and biomass transportation. This total energy value coupled with conversion efficiency was used to establish the minimum ovendry kg of biomass per kg amendment (N, P, K, Ca, and water) needed to justify the cultural investment. Published results from biomass production studies were analyzed using procedures established in this article. This article established the need to analyze both conversion and cultural management strategy in completing a comprehensive energy balance. Forest Sci. 28:459-469.
