Agriculture and Biodiversity

Biodiversity is the variation of life at all levels, from genes to organisms to populations. Healthy ecosystems tend to have greater biodiversity.

Most biofuel feedstocks come from agricultural crops grown in highly disturbed ecosystems with relatively …

Sustainable Feedstock Production with Grasses

There are several benefits to using grasses, such as switchgrass and miscanthus, as biofuel feedstocks. They grow on marginal lands, prevent soil erosion better than row crops, and require fewer inputs. Read below about the advantages and drawbacks of grass crops.

Switchgrass (Panicum virgatum) is a native warm-season grass that is a leading biomass crop in the United States. More than 70 years of experience with switchgrass as a hay and forage crop suggest switchgrass will be productive and sustainable on rain-fed marginal land east of the 100th meridian. Long-term plot trials and farm-scale studies in the Great Plains and plot trials in the
