Perennial biomass crops build soil carbon

Converting farm fields to energy crops can increase or decrease greenhouse gas emissions, depending on where – and which – biofuel crops are used, University of Illinois researchers report this month. The researchers analyzed data from dozens of studies to determine how planting new biomass crops can influence the carbon content of the soil. Their findings will appear next month in the first issue of the journal Global Change Biology Bioenergy – a new scientific journal in the Global Change Biology series, published by Blackwell.
