Cellulosic Biofuels Diversity Experiment at the Kellogg Biological Station, Hickory Corners, MI (2006 to 2017)

Dataset Abstract The Cellulosic Biofuels Diversity Experiment is an additional long-term study located within the LTER Main Site complex, in which a series of 12 different cropping systems vary in species makeup and nitrogen input. Treatments include continuous corn, corn-soybean, two variations of switchgrass fertilized differently, a C3 – C4 grass mix, and prairie grasses native to Michigan with different numbers of species. Switchgrass varieties are Cave-in rock (commercial non-native) and Southlow commercial native). Prairie grasses include switchgrass (Panicum virgatum), big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium), and Indian grass (Sorghastrum nutans),
Treatment plots are 9.1 by 27m (30 × 40 feet) replicated in each of 4 randomized blocks. The study site was established in 2008. Click on the image for a printable map of the study area. original data source http://lter.kbs.msu.edu/datasets/109

数据集摘要
纤维素生物燃料多样性试验是设于长期生态研究（Long-Term Ecological Research, LTER）主站点复合体中的一项补充性长期研究。该试验共设置12种不同的种植系统，其物种组成与氮素输入水平均存在差异。试验处理包括连作玉米、玉米-大豆轮作、两种施肥模式各异的柳枝稷（switchgrass）种植、C3-C4草本混合种植，以及物种丰富度各不相同的密歇根本土草原草本群落。
供试柳枝稷品种包括商业非本土品种岩洞（Cave-in Rock）与商业本土品种Southlow。供试草原草本植物涵盖柳枝稷（Panicum virgatum）、大须芒草（Andropogon gerardii）、小须芒草（Schizachyrium scoparium）以及印度草（Sorghastrum nutans）。
试验样地规格为9.1×27米（30×40英尺），在4个随机区组中均设置重复。该研究站点于2008年正式建立。点击图片即可获取可打印的研究区域地图。
