As the push for more biofuel crops remains strong, university researchers are looking into alternative crops that would be good for growing on marginal land.
Biofuel crops are most often relegated to marginal land since food crops are produced on the best land possible. However, the soil in marginal land is often salty, which is a significant challenge for producing any crops.
University of Illinois researchers are now experimenting with perennial grasses that can withstand salinity in marginal soils. The two main crops they are comparing are switchgrass and prairie cordgrass.
