This is the VOA SE English Agriculture Report .

Farmer in the United States , sometimes plan switch grass as a border clock . But would this top grass lower the nations dependence on foreign oil . The Department of Energy plans to invest hundreds of millions of dollars to help produce fuels from materials that are not part of the food supply . Growing coin or main spoil fuel has waste concern about the supply and cost of corn available for food and animal feed . Fewer main from switch grass or forest waste like Sodas is known as set you lose it / . Department official say it contains more energy and produces fewer greenhouse gases that / may from corn .

Swith grass is also easy to grow . Last month , the procedings of the national academy of science , publish a study of switch grass grow on low quality land . Goverment scientists can / was the leaf often , the study says the switch grass produce five times more energy than was leaded to grow . Also it says switch grass over its life time from cruck to fuel produce much less carbon compare to gasline . F. fuels like oil , take carbon from the ground and release it as waste gas fuel is burn . B. fuels like corn and / / also produce greenhouse gases throught growing crocks and making the fuel .

The difference that Bio fuel remove carbon from atmosphere throught the growth of the feed stop ,the material for the fuel . Science magazine just publish two studies of bio fuels and the heat trapping gases that seientists link to climate change . One of the report knowns that most studies have found that substituting bio fuels or gasline will reduce greenhouse gases . But it says the earlier studies fail to count the carbon release into the atmosphere as farmers worldwide react to hire prices . They are clearing forests and greenlands to make wave for new clockland to replace the green use for bio fuels .

Doing so can release much of the carbon store in the plants and soil and secrifies future storage . The study found that corn basic / could increase greenhouse gases for years from land use change and it found the bio fuels from Switch grass if grow on American corn land could also increase emission thought by less . The study team let by / searching jet at P. university says the result shows the value of using waste products for fuel . The other report says carbon savings depend on how bio fuels are produce .
