Abstract: Cellulosic bioenergy is a primary land‐based climate mitigation strategy, with soil C storage and N conservation important mitigation elements. Here we present 13 years of soil C and N change under three cellulosic cropping systems: monoculture switchgrass (Panicum virgatum L.), a five native grasses polyculture, and no‐till corn (Zea mays L.). Soil C and N fractions were measured four times over 12 years. Bulk soil C in the 0–25 cm depth at the end of the study period ranged from 28.4 (±1.4 se) Mg C ha−1 in n… Show more
