Composting Manure and Bedding Reduces Potential Soil and Phosphorus Loss (CIAS Research Brief 102)
Fertilizing fields with manure from dairy farms can contribute to elevated levels of phosphorus in waterways. Researchers at UW-Madison hypothesized that composting manure before spreading […]

How Does Organic Management on Dairy Farms Affect Pastures and Soils?
UW-Madison researchers explored whether limitations on the inputs allowed in organic farming may result in differences in plant-soil dynamics compared to conventional dairy operations, necessitating different grazing techniques. They found relevant scientific literature to be scarce.

Comparing Greenhouse Gas Emissions of Dairy Systems (CIAS Research Brief #101)
When researchers at UW-Madison compared greenhouse gas emissions of several different dairy farming systems in Wisconsin, they found that emissions were broadly similar between grazing and confinement dairies.

Analysis of Water Quality Impact of Windrow Composting
Composting is an ancient and cost-effective way to speed the decomposition of manure by piling it in rows and turning it regularly to aerate. For the last two years, three members of Yahara Pride Farms have been working with UW-Madison to determine whether composting can lead to reductions in phosphorus (P) runoff loads from their farms.

Whole-Farm Modeled Phosphorus Loss Low on Grazing Dairy Farms (Research Brief #94)
Because agriculture is a major nonpoint phosphorus pollution source, there is strong interest in identifying and managing farm sources of phosphorus runoff. On dairy farms, possible sources of this runoff include cropland, grazed pastures, and outside cattle holding areas such as barnyards and overwintering lots. A new study based on modeled data for four dairy farms that use managed grazing found that these farms have very low phosphorus losses on a whole farm basis.

Above- and below-ground grass growth responds to grazing management (Research Brief 91)
How is grass productivity above and below ground affected by grazing at different heights or by leaving different residuals after grazing? A study at UW-Madison found no simple answer to this question. Productivity of pasture grasses varies across grazing management strategies and species.

Growing the Pasture-Grazed Dairy Sector in Wisconsin
The vast majority of dairy cattle in the United States never see the outdoors while they’re lactating. Over 50% of the milk produced in
the US comes from just 1750 large farms, primarily in California, Idaho, New Mexico, and Texas. In contrast, about 22% or more than 3000 of Wisconsin’s dairy farmers use managed grazing. Can the unique features of milk from pastured cows contribute to the resurgence of an artisan dairy tradition?

Values-Based Food Supply Chain Case Study: Organic Valley
In 1988, a small group of organic vegetable growers in Wisconsin formed a cooperative to provide stable and fair prices to its members. It evolved into Organic Valley, the largest organic, farmer-owned cooperative in North America.

Managed Grazing’s Effects on Soil Quality and Structure
A long-term southern Wisconsin cropping systems study shows that soils under managed grazing have a number of positive characteristics compared to soils under other cropping systems.
