1a.Objectives (from AD-416)
To provide biomass suppliers with accurate guidelines for management of biomass removal and maintenance of soil quality.
1b.Approach (from AD-416)
Develop regionally applicable biomass feedstock harvest guidelines based on empirical and model analysis utilizing and enhancing available models; validate guidelines and recommendations through on-farm research trials; conduct regional sustainable biomass harvest round-table sessions with producers; characterize biomass feedstock and ash; assess impact of ash on plant growth and soil properties.
The overall goal of this project is to develop the data and tools necessary to assess long-term agronomic sustainability of removing corn stover residue for energy production, and is directly related to Objective 1 of the parent project: determine crop residue needs to protect soil resources and identify management strategies that enable sustainable production of food, feed, and biofuel and Objective 2, develop options for managing crop systems to reduce GHG emissions and increase C storage. The second set of on-farm plant samples were collected in the fall of 2010. A custom combine capable of harvesting grain, cobs and/or stover in one-pass was used. The incubation component of the project was initiated, which is assessing the impact of gasification and combustion products on nutrient cycling and greenhouse gas emission. The Authorized Departmental Officer's Designated Representative (ADODR) participated in regular project meetings, and made additional email and phone calls to scientific and farmer collaborators. Quarterly reports were prepared and submitted in a timely manner.
