2008 Annual Report
1a.Objectives (from AD-416)
Quantify how agricultural chemicals are transported to surface runoff under different cropping and management practices and identify Best Management Practices to minimize the pollutant loading to surface water sources.
1b.Approach (from AD-416)
Monitor water quality parameters at the St. Joseph River Watershed in NE Indiana under different cropping and management practices. Laboratory studies are designed to further the understanding of basic sediment and chemical transport processes. The field study will be used to expand the lab findings to real-world situations.
In FY08, the SJRWI continued to provide local support to maintain the water quality monitoring equipment at twelve monitored sites and preserved samples for subsequent laboratory analyses at the National Soil Erosion Research Laboratory. SJRWI also collected approximately 95% of farm/field cropping and 30% of field management data in the monitored sub-watersheds for water quality and economic assessment.
ADODR monitored through quarterly reports and e-mail or phone conversations as needed.
The SCA was terminated on June 30, 2008.
This accomplishment addresses NP211 Component 1 Effectiveness of Conservation Practices Problem Statement - to develop technologies for detailed assessments of conservation programs at a watershed scale, validate and improve models used to analyze relevant physical and chemical process, and support coordinated research on the effects of conservation practices across a range of resource characteristics (such as climate, terrain, land use, and soils).
