Overview/Theory
Because it is unlikely a single cellulosic biomass cropping system will satisfy multifunctional performance criteria in all agroecosystems, we are comparing the performance of corn, switchgrass, sorghum/triticale, triticale/soybean and trees/triticale over five landscape positions. Biomass samples are collected to represent the production of different feedstocks across the site.
Approach
The experimental site was established in 2008 with measurements beginning in 2009. Biomass samples were collected at the end of the growing season for each respective annual or perennial crop, with the exception of the aspen trees. Aspen trees were harvested at the end of year 4. Yields were determines on a dry matter basis.
