Interpretive Summary:

Technical Abstract: The present study explores the detailed chemical composition of corn stover fractions (husk, leaf, stalk, and cob) and whole corn stover harvested from different locations using different harvesting methods. Twelve corn stover bales were collected that vary in the harvest location and method. Each bale was separated into flakes, and grab samples from flakes at each end of the bale and from the middle were selected and combined in a container. Following this, the material was manually separated into pure anatomical fractions of stalk, husk, leaf, and cob. The composition of biomass was determined as per laboratory analysis protocol (LAP) from the National Renewable Energy Laboratory. Water-soluble and ethanol-soluble extractives were determined using the Soxhlet apparatus and a sequential extraction approach. The extractive-free biomass samples were subjected to a two-step acid hydrolysis process to determine structural carbohydrates (cellulose and hemicellulose) and lignin contents. Among all fractions, the ash content was found highest (up to 12%) in leaf fractions for all bales. The extractives were found higher (up to 23%) in the stalk fractions for almost all samples. Other data analysis is in progress.
