Research Project: ESTIMATING SUSTAINABILITY OF CORN STOVER REMOVAL FOR BIOMASS ETHANOL PRODUCTION IN SELECTED CORN BELT SITES

Location: Agroecosystem Management Research

2009 Annual Report


1a.Objectives (from AD-416)
1) Develop a summary of published and unpublished data on the impact of corn residue (stover) removal on future crop yield and soil quality.

2) Define and establish field experiment (specific to candidate locations for biomass ethanol plants) to assessing the impact of corn residue removal on future crop yield and soil quality.


1b.Approach (from AD-416)
Objective 1: ARS and Idaho National Lab (INL) will jointly prepare and publish an assessment of the impact of corn stover removal on future soil quality (SOC content and soil function) and crop productivity by summarizing literature, conducting new analysis of previously reported data and unpublished data from ARS experiments conducted in area of the Corn Belt identified by DOE as likely locations for the first biomass ethanol production facilities (biorefineries).

Objective 2: Plan, design, and implement long-term experiments to verify the analyses conducted and reported under Objective 1. These studies will be composed of new experiments or modified existing experiments, depending on location, factors under investigation, and historical and current data collection schedules and procedures.


3.Progress Report

The two objectives for this project have been accomplished. Two manuscripts have been published regarding the impact of corn residue removal on soil quality. A number of long-term experiments have been identified and several new field experiments have been initiated to assess the impact of corn residue removal on crop yield and soil quality. These experiments are now part of the Renewable Energy Assessment Project (REAP) multi-location project. ADODR monitoring was conducted via phone calls and e-mail.
