Day 1 | Eco-Ag U - Dan Kittredge - Principles of Biological Systems 8:30AM - 4:00PM
Ballroom Salon A-C — Dan Kittredge: Principles Of Biological Systems
Description:
Join farmer, educator, and founder of the Bionutrient Food Association Dan Kittredge for a deep dive into the core principles that drive biological farming systems.
In this intensive Eco-Ag U session, Dan distills decades of research and practice — including wisdom from Acres U.S.A. elders — into a simplified yet powerful framework designed to guide growers toward highly nutrient-dense crops.
Participants will explore how soil biology, mineral balance, plant vitality, and management practices intersect to influence the nutrient density of crops — and, ultimately, farm profitability. This integrated approach provides a roadmap for growers to observe, measure, and manage their systems more effectively.
You’ll leave this session with:
A clear understanding of the core principles of biological systems that underpin regenerative farming.
Practical strategies for aligning soil, plant, and ecosystem processes to increase nutrient density and crop quality.
Insights on how to apply these principles at any scale, from market gardens to broad-acre operations.
A renewed connection to the historical knowledge that laid the foundation for Acres U.S.A.’s ecological agriculture movement.
Whether you’re new to biological farming or refining an established system, this session offers tools and insights to elevate your operation and strengthen the link between soil health, crop vitality, and human nutrition.
Monday December 1st: 8:30am - 12:00pm
Day 1 | Eco-Ag U - Mark Shepard - Ecological Agriculture & Land Investment: Building the Farms of the Future 8:30AM - 4:00PM
Ballroom Salon E — Mark Shepard:
Description:
Regenerative agriculture doesn’t just heal land — it creates real, lasting opportunity. In this full-day intensive, Mark Shepard, author of Restoration Agriculture, explores how ecological design, water management, and smart land investment intersect to build profitable, resilient farms for the next generation.
Mark will unpack the economic and ecological frameworks that allow farmers, investors, and landowners to work together — creating partnerships that restore landscapes while generating long-term value. Through real-world examples and decades of experience, he’ll show how water systems, perennial crops, and integrated farm design can turn land ownership into ecological wealth.
This is the session for those looking to build — or invest in — the future of agriculture.

Salon F-H — Steve Campbell: Common-Sense Cattle
Description:
Join Steve Campbell—renowned rancher, consultant, and founder of Tailor Made Cattle—for an in-depth workshop exploring his signature Red Solo Cup Theory. This hands-on session will guide participants through the practical, visual, and measurable traits that indicate optimal cattle fertility, hormonal balance, and butterfat production. Using his iconic “solo cup” shape analogy, Steve teaches how to select low-input, high-output animals by observing glandular health, body conformation, and functional structure.
Participants will gain firsthand knowledge on:
Using hair coat, shedding patterns, and thymus expression to identify hormonal health
Applying linear measurement to evaluate the “solo cup” shape and structural correctness
Recognizing key butterfat indicators such as clean hocks, bald udders, proper tail shape, and ideal hooves and ankles
Selecting bulls and replacements that enhance herd fertility and longevity
Reducing inputs while improving calving ease, gain, and meat quality
Whether you're building a cow-calf herd, working toward a 100% grass-fed model, or aiming to increase ranch profitability, this workshop delivers powerful tools rooted in biology, observation, and decades of experience.

Description:
Led by Dr. Don Huber, Professor Emeritus, Purdue University
December 1–2, 2025 | Part of the 50th Annual Eco-Ag Conference | Madison, WI
Chemical agriculture once promised higher yields, cleaner fields, and a streamlined future. But today, glyphosate and its associated technologies have left behind depleted soils, weakened crops, chronic animal health issues, and growing concerns about food safety and human disease.
This two-day symposium, led by legendary plant pathologist Dr. Don Huber, brings together some of the world’s leading voices in soil science, toxicology, medicine, microbiology, and food system transparency to explore what comes next.
🧠 What You’ll Learn
- The chemistry and long-term effects of glyphosate on soil and biological systems
- Real-world research on glyphosate residues in food, water, animals, and people
- Links between glyphosate use and chronic illness, livestock disorders, and microbial collapse
- Emerging soil remediation practices and microbial detox strategies
- Proven alternatives to chemical weed control and conventional fertilization
- How to rebuild a functioning, profitable farm ecosystem beyond glyphosate
This symposium features a rare convergence of scientists, doctors, and farmers with deep firsthand experience confronting the glyphosate era—and building pathways beyond it.

2025 Speakers
But don’t just listen to us, here’s what past attendees have said!
"This was the best conference for 'wealth of information' I've ever attended."
"Love this conference! It's one I greatly look forward to each year. I enjoy the new and more seasoned presenters. I usually catch one of the film screenings - this is the first year I didn't even catch partial - too much to do. Really enjoy the cocktail mingle, meet and greet, the supply of water, the quality of the vendors, speakers. The layout and flow of the whole conference is one of the better ones and why it's easy to come back year after year."
"The vast amount of knowledge at the conference was palpable and I feel fortunate to have learned from some of the leaders in this movement. Thank you for giving Eco Ag a space in the farming world and for giving voice to the regenerative movement. I have so much to think about and apply to my farming operations. THANK YOU!!"
“The Eco-Ag U sessions are why I come and am willing to travel long distance. Very much appreciate being able to go in depth with one presenter for 1 or 2 days."
“Attending this conference has been an absolute game-changer for my farming practices. The depth of information and the quality of the speakers are unparalleled. The networking opportunities were fantastic, and I left with actionable insights and new connections. Can't wait for next year!”
"The vast amount of knowledge at the conference was palpable and I feel fortunate to have learned from some of the leaders in this movement.
