Wednesday talk

An integrated analysis tool to guide sustainable biomass production

This talk is about growing biofuels feedstock can have significant impact on agronomic systems. Because of the biofuels market is opening up, large amount of biomass feedstock is need for biofuel production. He mentioned three impacts: extensification (bringing new land into production), substitution (changing crops on existing acres), and intensification (increasing inputs). He uses different models to quantify the impact of biomass harvest. Six limiting factors are taken into consideration: loss of soil organic matter; soil erosion; loss of plant nutrients; soil water and temperature dynamics; soil compaction and Environmental degradation. He concludes that switchgrass would cause least erosion to the soil.
