2008 Annual Report
1a.Objectives (from AD-416)
To provide an economic assessment of selected conservation practices to meet desired environmental endpoints (e.g., improved water quality) within the Ft. Cobb Reservoir watershed at the farm scale. The objective for this research corresponds to sub-objective 3c.1 in CRIS entitled “Hydrologic Impacts of Conservation Practices in Oklahoma Watersheds” (6218-13000-0010-00D), and relates to the 48 month milestone for this sub-objective. Additionally, the objective corresponds to sub-objective 4a (goal 4.1 in milestone table) of the multilocation “Conservation Effects Assessment Project – The ARS Watershed Assessment Study.”
1b.Approach (from AD-416)
Water quality, meteorological, soil, and farm-level (e.g., equipment type and depreciation, herbicide and fertilize cost and usage) data will be collected and used within the Farm Level Economic Model (FEM) to determine the cost/benefit of adopting no-till and determine the length of time required to realize positive cash flow, as part of a decision support system development.
All the required water quality, meteorological, soil, and farm-level (e.g., equipment type and depreciation, herbicide and fertilize cost and usage) data were collected. Preliminary economic FEM simulation were conducted and studied to ensure that the assumptions made and data used were realistic. Revisions regarding the assumptions used and additional scenario runs were suggested. FEM simulation scenario runs are going on currently.
The ADODR monitored progress of the project through telephone conversations, email, and receipt of progress reports on the assumptions made and preliminary simulation runs.
