2012 Annual Report
The goal of this research is to develop a unified modeling framework for assessing the dependability of biomass supplies for use in the production of biofuels for the Navy. These simulation models are being developed, calibrated, and validated for use across Pacific Basin volcanic islands and globally which contributes to Objective 2 of the in-house project 5320-21610-001-00D which this project was originally established under (expired in FY2011). Excellent progress has been made in gathering parameterization data for the four key databases; weather, soils, crop parameters, and management, needed to run the ALMANAC (Agricultural Land Management with Numerical Assessment Criteria) model to evaluate best management practices (BMPs) that maximize biomass feedstock yields and associated environmental impacts. Information on the spatial and temporal variability of feedstock yields is also needed to ensure that enough biomass is produced to meet production demands. Weather – compiling of ALMANAC compatible annual weather data files for 18 HC&S stations has already been completed; Soils- ALMANAC uses the USDA NRCS SSURGO soils as input for the simulations.
Crop parameters- Considerable progress has been made in compiling crop parameters for sugarcane, energycane, and Napiergrass. These parameters are based on data collected from field trials established at HC&S and include; leaf area index (LAI), light extinction coefficient (Kc), maximum crop height and rooting depth, and nitrogen, phosphorus, and potassium nutrient uptake.
