Reducing lifecycle environmental impacts and improving profitability of Wisconsin dairy systems through improved cropping management
Agricultural soils are continuously degrading and about 70% of the carbon of agricultural soils has been lost worldwide due to soil erosion and unsustainable management practices. This project will assess…
-
Bringing artificial intelligence to the dairy barn
Farms have relied on human vision to observe and interpret animal behavior. As farm sizes increase and labor changes, it is more challenging to rely on human observations. The goal…
-
Local virtual enclosures to enforce managed grazing
Chris Wilson rotates his grazing dairy herd by manually moving lightweight fencing, which is cumbersome. Digital solutions for confining livestock exist, involving use of GPS collars. However, these systems are…

Green ammonia recovery from manure digester and lagoon by electrodialysis
Human expansion and intervention in the nitrogen cycle has led to a “lossy” system, particularly in manure handling. The ammonium ion is moveable using electrical fields similar to electrodialysis. This…
-
Efficacy of manure nutrient prediction and variable rate technology to improve nutrient use efficiency on Wisconsin dairy farms
Manure is a valuable resource for maintaining soil fertility on Wisconsin dairy farms. However, over-application causes soils to become saturated with nutrients, which can lead to surface and groundwater contamination.…
-
Evaluating nitrogen availability from solid-liquid-separated and composted manure
Manure is often applied to land to return organic matter and nutrients to the soil. Manure processing methods, such as solid-liquid-separation and composting, have grown in popularity to improve transport…
-
Full implementation of automated rotational grazing and assessment of its impact on animals and on forage
Pasture systems are an effective and potentially economical way to produce feed for livestock, but grazing management can be a challenge. Previous Hub-funded research developed two prototype systems, physical and…
-
Enhancing crop health assessment through acquisition of a porometer/fluorometer
Justen’s project will use a fluorometer/porometer to expand research capacity for novel research on dairy cropping systems and nutrient management at UW–River Falls. A fluorometer/porometer is an instrument that can…

Reimagining 131/132 Agricultural Sciences Building to accommodate Hub-funded equipment to build research capacity
Sumner-Davis’s project will renovate AGS rooms 132 and 131 at UW–River Falls to accommodate previously Hub-funded equipment, an environmental test chamber and plant growth chambers. PI: Heather Sumner-Davis Sumner-Davis is…
-
Supplemental funding for analytical lab and collaborative research space
Sumner-Davis’s project will use additional funds to complete renovations for the Analytical Lab at UW–River Falls, which will increase the college’s research and collaboration abilities. PI: Heather Sumner-Davis Sumner-Davis is…
