Positive associations of soil organic matter and crop yields across a regional network of working farms
The amount of soil organic matter (SOM) is considered a key indicator of soil properties associated with higher fertility. We quantified the relationship between SOM and yields of corn (Zea mays L.) and silage for a dataset of 170 fields arrayed across 49 farms in a network of growers based in Wisconsin and Minnesota.

Conservation benefits of a grade stabilization structure
A grade stabilization structure (GSS) is an on-farm conservation tool that can effectively decrease the amount of sediment and nutrient runoff entering nearby streams.

Characterizing phosphorus dynamics in tile-drained agricultural fields of eastern Wisconsin
Through collaboration with private landowners, surface and tile drainage was measured and analyzed for dissolved reactive P (DRP) and total P (TP) losses at four field sites in eastern Wisconsin between 2005 and 2009.

At-grade stabilization structure impact on surface water quality monitoring on an agricultural watershed
Use of an at-grade stabilization structure (AGSS) as an additional conservation practice to contour strip cropping and no-tillage, proved to be successful in reducing organic and sediment-bound N and P within an agricultural watershed located in the DA.

An at-grade stabilization structure impact on runoff and suspended sediment
We evaluated the ability of an at-grade stabilization structure (AGSS), designed as a conservation practice to reduce the amount of overland runoff and suspended sediment transported to the surface waters of an agricultural watershed.

Soil moisture and rainfall intensity thresholds for runoff generation in southwest Wisconsin agricultural watersheds
The goal of this study was to improve understanding of the factors that influence runoff generation during non-frozen ground periods in small agricultural watersheds in southwestern Wisconsin where the landscapes are controlled by dolostone bedrock in order to provide agricultural producers with a manure management tool.

Silage storage runoff characterization: Annual nutrient loading rate and first flush analysis of bunker silos
This research evaluated the runoff characteristics from six horizontal bunker facilities at dairy farms to determine runoff water quality and nutrient loading throughout a storm and annual nutrient losses.

Precipitation-runoff relations and water quality characteristics at edge-of-field stations Discovery Farms and Pioneer Farms
A cooperative study between the U.S. Geological Survey, the University of Wisconsin (UW)–Madison Discovery Farms program (Discovery Farms), and the UW–Platteville Pioneer Farm program (Pioneer Farm). Click here to read

Nutrients and sediment in frozen ground runoff from no-till fields receiving liquid daiy and solid beef manures
The data collected as part of this study add to the limited information on the quantity and quality of frozen-ground runoff at field edges, and the results highlight the importance of manure management decisions during frozen-ground periods to minimize nutrients lost in surface runoff.

Methods of data collection, sample processing, and data analysis for edge-of-field, stream gaging, subsurface, and meteorlogical stations at Discovery Farms and Pioneer Farms
Equipment used; station maintenance; sample handling and processing procedures; water-quantity, water quality, and precipitation data analyses; and procedures for determining estimated constituent concentrations for unsampled runoff events.
