The Conservation Effects Assessment Project (CEAP) was initiated by the USDA Natural Resources Service (NRCS), Agricultural Research (ARS), and Cooperative State Research, Education, Extension (CSREES) in response to a general call for better accountability of how society would benefit from 2002 farm bill's substantial increase conservation program funding (Mausbach Dedrick 2004). original goals CEAP were establish scientific understanding effects practices at watershed scale estimate...
Soil erosion and nutrient loss from surface runoff subsurface leaching are critical problems for cultivated land. Conservation initiatives show a persistent need field-scale cropland vulnerability assessments to inform farm management options prioritize efforts at watershed or regional scales. The Vulnerability Index (SVI) was developed by USDA9s Natural Resources Service (NRCS) assess inherent of using readily available soil topographic inputs: hydrologic group, slope, erodibility K-factor,...
The Soil Vulnerability Index (SVI) was developed by the USDA Natural Resources Conservation Service (NRCS) to classify inherent vulnerability of cropland soils based on field sediment and nutrient transport resulting from surface runoff leaching. primary purpose SVI is aid conservation planners in more rapidly assessing managed lands resource concerns. index hydrologic soil group, slope, erodibility for cultivated soils, with addition percentage rock fragments organic matter when considering...
After the first decade of CEAP, results indicated increased adoption minimum soil disturbance technologies and winter cover crops, a renewed emphasis on riparian corridors.This article builds these previous efforts introduces research papers feature in special issue that focuses findings ARS Benchmark other CEAP watersheds during 15 years watershed assessments.This also presents brief synthesis impacts, mainly NIFA-CEAP watersheds, highlights some key CEAP-developed technologies.The paper...
Lake Erie has a long and storied history with water quality impairment conservation. Following the passing of Clean Water Act in 1970s, total phosphorus (P) loading to lake substantially decreased through permitting point sources conservation efforts decrease sediment loss from agricultural fields. While P losses have remained relatively stable since 1990s, dissolved increased resulted increases extent severity algal blooms over past two decades (Smith et al. 2015b). Both industry...
Conservation practices are effective ways to mitigate non-point source pollutions, especially when implemented on critical areas (CSAs) known as the contributing disproportionately high pollution loads. Although hydrologic models promising tools identify CSAs within agricultural landscapes, their application is limited where data and modeling expertise available. The Soil Vulnerability Index (SVI) developed by USDA-Natural Resource Service (NRCS) Effects Assessment Project (CEAP) regarded a...
Decision support tools (DSTs) are a means to facilitate science-based conservation planning. Technical advancements in science, the pragmatic needs of planning, and government for collaborative initiatives such as Conservation Effects Assessment Project (CEAP), have contributed evaluation development both existing new DSTs. Much current scholarship on DSTs, however, focuses their uptake by farmers crop advisors. Limited, almost no, attention has been paid education training agency staff—the...
Quantifying the impacts of Conservation Effects Assessment Project watershed assessments: The first fifteen years
To better understand agricultural nutrient losses, we evaluated relationships between management (e.g., manure and tillage), soil health measurements, resulting edge-of-field (EOF) surface water quality. This work was conducted before or early into conservation implementation at 14 Great Lakes Restoration Initiative EOF sites spanning Wisconsin, Michigan, Indiana, Ohio, New York. Analyses of site characteristics (hydroclimate, management, catchment properties) along with 3 yr measurements...
The USDA Natural Resources Conservation Service (NRCS) has proposed the Soil Vulnerability Index (SVI) as a standard tool to classify inherent soil vulnerability of cropland loss sediment and nutrients by runoff leaching. uses properties topography, does not consider crop management, except for presence artificial surface or subsurface drainage. For artificially drained cropland, SVI remains unchanged but leaching is raised two classes out four reflect increased risk nitrate (NO<sub>3</sub>)...
Water quality monitoring is used throughout the world to assess of water resources. Data and analyses from assessments can be inform policy as well program design, delivery approaches, practice adaptive management enhance outcomes. Many these have demonstrated problems associated with nutrient enrichment sedimentation resources (Chapman 1996; Dubrovsky Hamilton 2010; Scott Gemmell 2013). Not surprisingly, because its land area necessary inputs support food production services, agriculture a...
Abstract The buffering of phosphorus (P) in the landscape delays management outcomes for water quality. If stored labile form (readily exchangeable and bioavailable), P may readily pollute waters. We studied its intensity >600 soils sediments across seven study locations United States. Stocks were large enough to sustain high losses decades, indicating transport‐limited regime typical legacy P. Sediments commonly more P‐sorptive than nearby soils. Soils top 5 cm had 1.3–3.0 times at 5–15...
