This free, open-access textbook by Valerie Dantoin of Northeast Wisconsin Technical College covers soil science fundamentals for organic producers — including physical properties, soil chemistry, organic matter, nutrient cycling, soil testing, fertilizers, compost, living soil biology, livestock integration, erosion prevention, cover cropping, and tillage — with real farm case studies and a chapter on urban soils.

In this webinar, produced by Albert Lea Seed, farmer Scott Myers from Woodlyn Acres Farm (Dalton, OH) discusses how to interseed winter small grains into organic soybeans for weed suppression. He offers guidance on topics including field preparation, planting, weed control, and harvest, outlining his own successes and failures and sharing tips to help others succeed.

The purpose of this project was to find a way to make aphid-infested broccoli heads marketable by inducing the aphids to walk away in response to alarm pheromone. Organic broccoli can be made unmarketable when aphids infest the head. Aphid…

A diverse and virulent complex of pathogens threaten organic tomato production. The Tomato Organic Management and Improvement Project (TOMI): Part II builds on previous research which found that soil and root microbiomes play a substantial role in mediating crop disease resistance. This research investigates: 1) the potential for microbial biocontrol agents to promote disease suppression, 2) how plants and microbes interact, and 3) the development of varieties with stable disease resistance.

CCOF's free Producer Media Toolkit helps organic and small-scale farmers connect with local media. The toolkit provides guidance on selecting and capturing compelling photos, preparing for media interviews, crafting key messages, and building lasting reporter relationships — so your farm's story gets told the way you want it told.

Join Dr. Touyee Thao, Research Scientist at UC Agriculture & Natural Resources, for a discussion about the potential benefits of incorporating biochar and dairy manure amendments into organic vegetable production systems. Learn about what ratios work best when adding biochar and dairy manure, and how these amendments impact soil health, GHG emissions, and tomato productivity.

Commissioned by USDA's Transition to Organic Partnership Program (TOPP), this 2025 report identifies a critical shortage of qualified organic inspectors and certification reviewers — with 82% of certification bodies lacking sufficient inspectors. It examines workforce demographics, skills gaps, career entry barriers, and training access, recommending coordinated industry action to grow and strengthen the organic certification workforce.

This webinar, Part 1 of a two-part series “No-Tilling Organic Corn into Living Alfalfa,” presents the research findings of a study conducted by Dr. Erin Silva from the University of Wisconsin-Madison, in collaboration with Cornell University, on the outcomes of planting organic corn into living mulches (including alfalfa, red clover, and yellow clover).

By establishing nest boxes in vineyards, organic growers can create suitable breeding habitats for native songbird populations, particularly the Western Bluebird. These bluebirds rely on insects for food and serve as important natural preda…

Low soil fertility, intense weed pressure, and climate disruption threaten the economic viability of organic dryland wheat production in the western US. Previous OREI-funded research indicated that a one-time application of composted cattle manure + bedding can double soil organic carbon (SOC) and organic dryland wheat yields for at least 15 years after application.  The current study explores this compost legacy effect in greater depth, its underlying mechanisms, and the scope and duration of benefits.

These reports, produced by the USDA Agricultural Marketing Service, provide current national price data and market overviews for products that have been grown, processed and certified to USDA’s National Organic Program standards.

Join Dr. Hoyoung Kwon, Environmental Analyst at the Argonne National Laboratory, for a discussion about how life cycle analyses (LCAs) can be used to identify major agricultural greenhouse gas contributors and to develop ways of reducing the agriculture sector’s contribution to the climate crisis.
