Evidence of Switchgrass Improving Soil and Crop Yield
- Here is a summary of a study done by Oak Ridge National Laboratory that shows the power of Switchgrass to add carbon to the soil and increase subsequent crop yield. Switchgrass, progenitor of the North American prairie, is now being considered by the government to produce biomass for biofuel, but it does something much more fundamental--it creates fertility. What a waste to grow miles of switchgrass to power cars that could be powered by electricity stored in ultracapicators, when the same grass could be used throughout the US to fertilize soil naturally. Perhaps the two goals are not mutually exclusive, however. If great masses of land were planted in switchgrass in the hope of producing biofuel, and the development of the electric ultracapicator car decreased the demand for such fuel, then we would be left with miles and miles of wonderfually arable and fertile land. Switchgrass. of course, is only one of many deep-rooted perennial grasses that naturally fertilize land
and add carbon.
