Soils and Weed Management

Building a healthy soil is the foundation of organic farming and applies to all aspects of farm management, including managing weeds. In this webinar, Steve Diver discussed plant succession, weed ecology, and weeds as indicators of soil conditions, mineral accumulators, and "Nature's Signals". Warren Dick discussed soil characteristics and how to improve the health of a soil with the use of gupsum. Jean-Paul Courtens was the last speaker in the webinar, presenting the soil and weed management practices they use on Roxbury Farm, from managing soil fertility to cultivation and weed suppression.

Applied Weed Ecology: Why Weeds Grow and Ways to Observe Them - Steve Diver, University of Kentucky

Steve Diver has been working in organic agriculture for over 30 years in numerous roles, including as an organic farmer, horticulture agent, consultant, and as an ATTRA specialist for 18 years. He just recently started a position as the superintendent for the University of Kentucky Horticultural Research Farm.


Soil Quality and Weeds - Warren Dick, The Ohio State University

Warren Dick is an agronomist with the Ohio State University. His research has focused on soil biochemistry, microbiology and environmental soil chemistry and no-till production systems. He is the caretaker of the longest no-tillage plots, having been continuously no-tilled since 1962.


Soil Management for Better Weed Control - Jean-Paul Courtens, Roxbury Farm

Jean-Paul started Roxbury Farm in 1990 in Claverack after starting the vegetable garden at Hawthorne Valley Farm. Jean-Paul attended a 4-year training school for Biodynamic Agriculture in the Netherlands before he emigrated to the United States. In 2000, Roxbury Farm moved to new land in Kinderhook, gaining secure land tenure in perpetuity. Jean-Paul works constantly to maintain and build soil fertility on the farm. He hopes to change our outlook on soil by calling it "earth" instead of soil or dirt as this implies something unpleasant (you soil your clothes or you get your hands dirty). Jean-Paul has developed many resources on his farming practices, including his manual on soil management.

Different Approaches to Weed Management



Organic farmers manage weeds in very different ways for a variety of reasons. In this webinar three organic farmers will discuss the strategies they’ve developed for managing weeds, their reasons for selecting those practices, and the conditions necessary for those methods to be successful.


Powerpoint Slides from webinar

Patrice Gros, Foundation Farm
Patrice was raised in Marseille, France. In 1993, while pursuing a career in corporate finance, Patrice bought a home in Ojai, CA, with an acre of land where he started his first garden, heart-shaped and barely 100 square-feet. With it came a life transformation of the most profound and unexpected kind. Thousands of hours of raking, mulching and harvesting later, Patrice’s passion is alive and well. Only the scale has changed. In 2006 Patrice founded Foundation Farm, a 5-acre USDA certified organic farm in Northwest Arkansas. Foundation Farm follows a no-till, low-input system which provides high yields in a beautiful natural setting. In 2013 Foundation Farm harvested 20,000 lbs of produce that were sold within a 50-mile radius.


Jeff Evard, One Sky Agriculture Enterprises and Herr Station Malt
Jeff Evard earned a degree in agronomy from Purdue before starting several farm ventures. He started LIFE Certified farm, growing vegetables for the farmers’ market and CSA. He became interested in breeding vegetables and collaborated with friends to start a seed company. He is now expanding his operation to include a new venture: rye. He initially incorporated rye into his rotation for pest management, but is now increasing his production to sell to local breweries.


Martin Diffley, Organic Farming Works
Martin Diffley is an organic farming, activist, and consultant. He started the Gardens of Eagan, an urban-edge organic vegetable farm, on his 5th generation family land in 1973. One of the first certified organic vegetable farms in Minnesota, Martin has extensive experience in transitioning land to organic, innovative marketing, small and mid-size farm equipment, soil-based fertility, and organic weed and pest management. His current on-farm projects include, breeding of sweet corn, mentoring beginning farmers, and transitioning chemically farmed land to organic.

Educator Webinar: Adapting Our Message To Better Reach Organic Farmers

Powerpoint Slides from webinar

This webinar will discuss factors influencing how organic farmers decide to manage weeds and how educators can adapt their message and extension efforts to better reach organic farmers. We'll also discuss new resources being developed to use with organic farmers.

Alan Sundermeier serves as Co-Coordinator on the Sustainable Agriculture Team and the Ohio State Sustainable Agriculture Research and Education (NCR SARE) Program. He has been an Ohio State University Extension Educator for 13 years. He specializes in agronomic crop production focusing on cover crops, soil quality, and organic grain production. Sundermeier holds a Bachelor of Science degree in Agriculture (1977) and a Master of Science degree in Environmental Management (1995). He was raised on a crop and livestock farm in Northwest Ohio. He and his wife Sandra have 3 children.


Sarah Zwickle is a research associate on the Organic Agriculture Research Extension Initiative (OREI) project, which this webinar series was a part of. Her role on the project was to study organic farmers’ decision-making process related to weed management. Her research provided the basis for much of this project’s extension efforts and she shared some of the results from her research in this presentation.


Eric Gallandt, University of Maine
Eric received his B.S. (1986) from Michigan State and M.S. (1988) from Montana State University. He received his Ph.D. from the University of Wisconsin in 1994. He joined the faculty at the University of Maine in 2000 and is an Associate Professor of Weed Ecology. His research program works at the interface of two principles of sustainable agriculture: the need to maintain or improve soil quality and the use of ecological approaches for pest management, specifically weeds.
