Sustainable integrated agricultural management practices - Prospects of a sustainable production of biomass
Influence of Marginal Soils on the Productivity and Energy Balance of Sorghum Use for Energy
Short Introductive summary
This work analyses the influence of marginal soils on the productivity, biomass quality, and energy balance of sorghum (Sorghum bicolor L.), assessing its potential as a sustainable energy crop. The study was based on a comparative analysis of scientific literature addressing sorghum productivity and biomass quality, as well as on energy balance calculations for different conversion routes: combustion, combined heat and power (CHP), gasification, pyrolysis, alcoholic fermentation, and lignocellulosic hydrolysis/fermentation. The total energy input for sorghum cultivation was estimated at 12.6 GJ/ha, including diesel, fertilizers, seeds, pesticides, and machinery. Two productivity scenarios were considered: 4 t/ha, representing marginal soils with water or nutrient limitations, and 45 t/ha, corresponding to favourable edaphoclimatic conditions.
