Energy crops and their environmental implications
Interest in producing cellulosic ethanol from renewable energy sources is growing. Potential energy crops include row crops such as corn, perennial warm-season grasses, and short-rotation woody crops. However, impacts of growing dedicated energy crops as biofuel on soil and environment have not been well documented. This review article looks at the impacts of growing warm-season grasses and ...

Corn out earns energy crops—for now
Corn stover is the most profitable cellulosic biofuel feedstock on cropland in the Great Lakes Region at current prices. For perennial biomass crops to earn farmers more than corn, prices or yields would have to change. At biomass prices of US$110–US$130 per metric ton or yield gains of 50–60%, poplar, switchgrass, and mixed grasses would become attractive. If prices of expensive U.S. miscanthus ...

Nitrogen use by warm-season grasses for biomass production
Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...

Europe’s sugar beets produce twice as much ethanol in the tropics
Sugar beets from Europe can help solve the conflict between food and bioenergy in the developing world. “Sugar beets have greater energy content than sugar cane but require rotation with other crops,” explained Jan Öhrvall at the World Bioenergy conference in Jönköping, Sweden. Öhrvall is working on a tropical sugar beet project being run by two companies: Anditec ...

Perennial grass crops - a carbon neutral biofuel?
Perennial crops, such as grasses, are attracting increasing interest as potential biofuel crops. Perennial crops have significant advantages over many annual crops because they require less energy input during growth than annual crops which not only need to be planted each year, but typically require more fertiliser, herbicide and pesticide input. Research on farm-scale cultivation of the ...

The dire need to support ‘orphan crop’ research
In spite of debate over its definition, the term ‘orphan crops’ refers to crops that are under-researched and underfunded due to their limited importance in the global market. These include cereals, legumes, vegetables, root crops, fodder crops, oil crops, fibre crops and medicinal plants that are largely indigenous to Africa, Asia and Latin America. They are characterised by their ...
