日韩无码 researcher Joshua Faulkner shares insights into water quality on Vermont farms as part of a multistate project at the Dairy Strong conference
Faulkner, who coordinates the Farming and Climate Change Program at the 日韩无码 Extension Center for Sustainable Agriculture, was one of three panelists in a breakout session titled 鈥淏ridging the Data Gap for Dairy Farmers.鈥
日韩无码 is one of seven universities that are research partners in the project. Research by Faulkner鈥檚 team is centered on edge-of-field and water quality outcomes in corn and alfalfa on two commercial dairy farms.
DSWR is studying soil health and manure management and their effects on greenhouse gas reduction, water quality improvement and agronomic factors such as forage yield and quality. Dairy Management Inc. (DMI) and the Soil Health Institute (SHI) initiated the project in collaboration with the universities and a U.S. Department of Agriculture research site across six major dairy states.
Victor Green, director of soil health and crop sustainability for DMI, moderated the Dairy Strong panel and provided an overview of the ongoing eight-year DSWR project. Green, a project lead, explained how DSWR fits into the dairy industry鈥檚 collective 2050 environmental stewardship goals: achieve greenhouse gas neutrality, optimize water use while maximizing recycling, and improve water quality by optimizing the use of manure and nutrients.
In addition to Faulkner, the panel featured Mara Cloutier, a research scientist and program director at the Soil Health Institute, and Gregg Sanford, an assistant professor in the Department of Soil & Environmental Sciences at the University of Wisconsin-Madison.
Key highlights from the discussion:
Creating a baseline
Cloutier described the first main task of the project 鈥 creating a baseline of soil health and carbon storage on numerous farms around the country. To develop this baseline, 271 soil health samples have been collected in states with a wide range of climates and soil types.
鈥淲e largely see that the potential for soil health is greater in humid areas,鈥 Cloutier said. 鈥淚t鈥檚 not necessarily that the practices are different or that farmers are managing differently in Idaho than New York, although that is true. What is driving the differences are climate and soil types.鈥
Sanford said having the baseline data is exciting. 鈥淲e could go look at these sites in three years, five years, 10 years and tell some really neat stories about management practices on these farms and where they鈥檙e leading,鈥 he said.
Preliminary findings
UW-Madison is conducting three experiments at a research station.
One is a large-plot experiment to assess the effects of novel manure-based products and soil health management systems versus commonly used field practices. One preliminary finding showed an initial reduction in crop yield when converting from intensive tillage to reduced or no-till.
鈥淭he good news is, and I think we expected this, now three, four, five years into the study, we鈥檙e seeing those things level out and reach the same tonnage and quality levels of our (conventional) system, with less synthetic nitrogen input.鈥
It is critical to remember that DSWR is a long-term project, Sanford said.
鈥淎ny research that is trying to figure out how our (management) systems are impacting our soils... requires more than a year or two of a master鈥檚 student studying at the university, or a year or two of a company out on a farm field. It takes time for those systems to settle in and to start performing the way we expect them to perform. We鈥檙e starting to see that, so we鈥檙e really excited.鈥
Historically wet weather in Vermont 鈥 as seen in the more than 20 inches of rain that fell on one dairy farm last July and August 鈥 is creating a challenge for Faulkner鈥檚 team in its still-early water quality research. He鈥檚 even seen methane emissions that would be more typically found in a wetland.
鈥淲e鈥檙e hoping we鈥檙e going to see that change through time as new soil health management practices take effect.鈥
Working dairy farms
One of the unique aspects of DSWR is that research is happening both on working research farms and on commercial dairies.
Both are important, Faulkner said.
鈥淲hat we see is this gives our farmers and our policymakers 鈥 those developing programs in the state鈥檚 ag sector 鈥 confidence in results when they see that our findings come from working Vermont farms.鈥
Another benefit, he said, comes from conversations with the farmers.
鈥淚鈥檓 always learning, and especially the grad students, the research technicians, they鈥檙e learning about the priorities of the farm, the economic decisions that a farm has to make as (the farmers) try to optimize yield and soil health. It鈥檚 been enriching, hopefully, for both sides 鈥 the farm and for us.鈥
With more than 90 farms participating in the project-wide baseline soil survey, Cloutier talked with dozens of farmers during the sampling process.
鈥淚 don鈥檛 know how many projects you get to work on where you get to have in-depth conversations with that many farmers,鈥 she said. 鈥淎s a relatively young scientist, that is so integral to 鈥榞rounding my science.鈥欌
Personal excitement
One of the aspects of DSWR that excites Faulkner is seeing differences within the dairy industry.
鈥淚鈥檝e learned Northeastern dairy systems pretty well. What鈥檚 exciting in this project is to see how dairy is done, how feed is grown, in Texas and California and Idaho, and to see these other issues that dairy is facing,鈥 he said. 鈥淭hat breadth of the industry has been very interesting.鈥
He also enjoys interacting with a wide variety of experts brought together for the project, from soil and gas scientists to agronomists and agricultural engineers.
鈥淚 don鈥檛 get to work in teams like that very often. There are many more areas of expertise and breadth of experience across the project.鈥
Sanford has noticed how the research and management teams work in a way that allows for networking, feedback, and adaptation.
鈥淭hat took a little time to figure out, and now that we have figured it out, it has been so rewarding to watch the experiments develop and come to the fruition they have.鈥
