Those who consider the use of port-harvest forest residuals as a feedstock for biofuel or energy production are interested to know how biomass removal affects soil temperature, water retention and nutrient levels. These effects are being measured at Long-Term Soil Productivity Sites (LTSP) throughout the U.S including the NARA LTSP site in southern Oregon. As the name implies, …more
