A narrative of agronomic activities on the Cellulosic Biofuels Diversity Experiment.
This datatable is part of the Cellulosic Biofuels Diversity Experiment dataset.
This dataset contains data from the Cellulosic Biofuels Diversity Experiment established in 2008 at the LTER Main Site and consisting of 12 different cropping systems (CE1-CE12) that vary in species makeup and nitrogen input. Treatments include continuous corn, corn-soybean rotations, two varieties of switchgrass fertilized differently, a C3 – C4 grass mix, and prairie grasses native to Michigan with different numbers of species. See the plot map for treatment details and Related Tables for seed species and planting details. Treatment plots are 9 × 27 m replicated in each of 4 randomized blocks. Plots are harvested annually in the fall and crop yields are recorded.
