Multifunctional Agriculture: A New Paradigm of Mixed Cropping
The dominant agricultural paradigm in prime cropland areas of the American Midwest are farms producing corn and soybeans. Within this region, some states in the Mississippi River Basin have developed nutrient loss reduction strategies aimed at decreasing nutrient loading in rivers that contributes to the hypoxic “dead zone” in the Gulf of Mexico. While several conventional conservation practices applied to corn-soybean fields can reduce nutrient loss, converting annual crop acreage to perennial biomass crops would be far more effective. New and expanded uses and markets for perennial biomass crops are needed in order for them to gain wide adoption. Bioenergy grasses can be used for various bio-based products and for…
