Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

An ideal crop would use water and light efficiently to maximize the amount of biomass, keep carbon in the soil instead of releasing it into the atmosphere, and require little nitrogen fertilizer, which can leach into water or react with soil to produce nitrous oxide (N 2 O), a potent greenhouse gas. Energy sorghum falls somewhere in between.
