Cropping Systems for Biomass Feedstock Production in the North Central Region, USA

M. Berti, D. Samarappuli, R. Nudell & B. Johnson
The ability to integrate bioenergy feedstocks into existing agriculture production systems without straining existing food, feed, and fiber supplies requires advanced crop management. Two strategies to advance towards this objective were studied, 1) use of cover crops before energy-dedicated crops, and 2) use of alfalfa-grass mixtures to produce biomass with lower nitrogen input. To meet the first objective seven cover crop treatments were planted in the fall followed by five annual biomass crops. Results across...
