Agricultural management legacy effects on switchgrass growth and soil carbon gains

These datasets are part of the manuscript \"Agricultural management legacy effects on switchgrass growth and soil carbon gains\" in which we observed the impact of historic tillage management and historic and continued N fertilization on switchgrass growth and soil C gains. In this study, we hypothesized that the inconsistencies in soil organic carbon (SOC) accrual by switchgrass might be due, in part, to differences in prior land management among the systems subsequently planted to switchgrass. To test this hypothesis, we measured SOC and other soil properties, root biomass, and switchgrass growth in an experimental site with a 30-year history of contrasting tillage and N-fertilization treatments, seven years after switchgrass establishment. We determined switchgrass’s monthly gross primary production (GPP) for six consecutive years and conducted deep soil sampling. Nitrogen fertilization expectedly stimulated switchgrass growth, however, a tendency for better plant growth was also ..., , # Agricultural management legacy effects on switchgrass growth and soil carbon gains
