Abstract
This proposal is submitted under the Innovative Tools and Techniques Supporting the Practical Uses of Earth Science Observations topic. We seek to evaluate and demonstrate technical approaches for linking remote sensing rangeland products with a soil biogeochemical model to form a decision support system for improved rangeland management. The resulting decision support system will be unique and innovative by not only providing operational remote sensing observations of rangeland condition, but also web-based tools that utilize these observations to provide critical information on soil fertility/productivity, greenhouse gas emissions, and potential erosion and sedimentation. Our Rangeland Decision Support System will build off of existing RANGES and DNDC tools. Landsat and MODIS prototype processing algorithms for rangeland condition (height, forage production, fractional cover) have been developed under the previous RANGES project. Our decision support system will couple RANGES products with the DeNtrification-DeComposition (DNDC) model. DNDC is a unique, spatially explicit, soil biogeochemical model that simulates both aerobic and anaerobic soil conditions, estimates crop yields based on a detailed crop physiology-phenology model, and is designed for assessing the net impact of alternative management on long-term soil organic carbon (SOC) dynamics and emissions of N2O, NO, CH4, and NH3 for upland and wetland agricultural ecosystems.
