Research Project: SPECIES AND ANALYTIC COMPOSITION OF CONSERVATION BUFFER VEGETATION FOR CELLULOSIC FEEDSTOCKS

Location: Soil and Water Conservation Research

2012 Annual Report


1a.Objectives (from AD-416):
Analyze the biochemical composition and species diversity of vegetation grown for riparian conservation buffers in the agricultural landscapes of the semiarid Pacific Northwest to determine suitability for biofuel feedstocks.


1b.Approach (from AD-416):
A split plot, randomized complete block (RCB) design experiment was conducted in dryland wheat fields representing low, intermediate, and high rainfall zones to evaluate perennial bioenergy and forage crop production potential. Six representative, 0.4 ha sites were identified, with two sites assigned to each precipitation zone. From within each of these sites, vegetation samples were collected from 1m2 plots, the vegetation separated by species, oven dried at 60C for 24 hours and ground in preparation of biochemical composition analysis.


3.Progress Report:

In cooperation with Oregon State University, we completed analysis of aboveground productivity and biochemical composition of cool season grasses in one of the major small grain producing counties in northeastern Oregon. A manuscript summarizing the results of research was submitted for publication in the Journal of Renewable and Sustainable Energy. This research supported objective 2A of the parent project by providing ARS and OSU scientists with information that can be used to evaluate the quantity and quality of biomass feedstock for sustainable bioenergy production under the low, intermediate, and high rainfall environments of the inland Pacific Northwest.
