CONSERVATION EFFECTS ASSESSMENT PROJECT (CEAP 2011)-ARS BENCHMARK WATERSHED STUDIES
Soil Drainage Research
2012 Annual Report
1a.Objectives (from AD-416):
Principal focus of the CEAP Watershed Studies is to evaluate the effects and benefits of conservation practices at the watershed scale, in support of policy decisions and program implementation.
1b.Approach (from AD-416):
The effects of conservation activities on water and soil quality will be assessed at the watershed scale using models such as ARS' Soil and Water Assessment Tool, in combination with ARS long-term watershed data sets, expertise, and resources.
Progress continues to be made on quantifying the impacts of conservation practices at the watershed scale in support of the national Conservation Effects Assessment Project (CEAP). Currently, efforts are underway to promote the adoption of cover crop usage in the watershed by our cooperators through a Cooperative Conservation Partnership Initiative (CCPI) grant. These efforts generate practice adoption sites where we obtain data regarding the impacts of cover crop adoption on edge of field water quality. Over the course of the project, we plan to quantify the impacts of cover crops at both the edge-of-field and watershed scale. In addition to the water quality research, progress continues to be made on assessing aquatic communities and habitats in differing headwater streams with the watershed. Data is made available through the STEWARDS database.
The work and progress associated with this project support objective 1 of the parent project, specifically sub-objective 1a: Quantify the influence of conservation practices on surface discharge and water chemistry in the agricultural landscape.
