Extension Publications

Intro to Dry Farming Organic Vegetables (EM 9229) - This publication provides an overview of dry farming, describes some of the management practices that support growing organic vegetable crops without supplemental irrigation in this region, and offers some additional resources.

Advances in Dryland Farming in the Inland Pacific Northwest - Farmers make tough decisions all the time—it comes with the territory. When that territory includes the dryland region of the inland Pacific Northwest, decisions can be even more challenging. Fluctuating weather, varying soils, and changing pest pressures are just a few of the ongoing challenges that farmers in this region face. However, university-driven research in these production areas can provide guidance. Packed with tools, resources, and the most current research, this book supports farmers as they make decisions relating to productivity, resilience, and their bottom lines.

Organic Dry-Farmed Tomato Production on California's Central Coast - A Guide for Beginning Specialty Crop Growers - This guide describes the steps involved in growing dry-farmed tomatoes organically on the Central Coast of California, with a focus on proper soil preparation, planting, and weed control.

Soil Survey Resources for Small Farms - Learning about the different types of soils on a farm is invaluable. Oregon alone has nearly 1,000 different kinds of soil, ranging from deep to shallow, clayey to sandy, nearly level to steeply sloping. These differences are important, because different soils require different kind of management practices. 

'Evaluate Your Site for Dry Farm Potential' - This double-sided handout created by Alex Stone, Andy Gallagher, and Matt Davis lays out the basics of assessing and improving site suitability for dry farming.

2016 Dry Farming Trial Report - This report details the methods and results for the 2016 dry farming demonstration which included two irrigated plots and two dry farmed plots (tomatoes, potatoes, squash and melon). One of the dry farmed plots was amended with a bokashi biochar compost.

2017 Dry Farming Collaborative Trial Reports

  • Oak Creek Center for Urban Horticulture - Includes methods and results for a tomato trial that included both grafted and ungrafted tomatoes in irrigated and dry farmed treatments. Also, the beginnings of effort to do participatory plant breeding for dry farmed systems is documented with a dry bean variety called 'Beefy Resilient Grex' from plant breeder Carol Deppe of Fertile Seeds.
  • Lewis Brown Farm - The OSU Lewis Brown dry farm trial site is .69 acres and has multiple varieties of tomatoes, squash, melon, zucchini, dry beans, and flour corn. This is the first year this field has been dry farmed and intended to be the ‘mother trial’ for the 2017 replicated variety trials with the Dry Farming Collaborative (DFC). Thirty DFC farms throughout Western Oregon and Washington are growing some of the same crop varietals. Note: This site had major issues with symphylans and cucumber beetles, so data in this reports reflects our results given those issues.


California Ag Water Stewardship Initiative - The California Agricultural Water Stewardship Initiative (CAWSI) aims to raise awareness about approaches to agricultural water management that support the viability of agriculture, conserve water, and protect ecological integrity in California.


Dry Farming Project Continues to Expand - Oregon Small Farm New article highlights the multiple research projects engaging with the Dry Farming Collaborative in 2018

The Dry Farming Collaborative: Co-creating the future of how we manage water on our farms - This article in the Rural Connections magazine aims to raise awareness about the Dry Farming Collaborative DFC) and it's importance to sustainable agriculture in the maritime Pacific Northwest by providing a brief overview of dry farming, a timeline of the OSU Dry Farming Project, it's evolution into the DFC, and potentials for the future.

Innovations in Dryland Farming - This article by Kym Pykorny in Oregon's Agricultural Progress highlights how we examples of how we are growing food with far less water in Eastern and Western Oregon.

Common Misconceptions and Key Points About Dry Farming - Case Study of Dry Farmer with More than 40 Years of Experience - A 2014 case study of a grower who farmed in CA without any form of irrigation for 40 years before retiring to 9.6 acres in Veneta, OR in 2007 where he now farms with no water rights.

Dry Farming Vegetables: One Farmer's Approach to Building Soil, Conserving Water, and Producing Great Tasting Tomatoes - A 2013 case study of Jeannie Berg, a fruit and vegetable grower in Monmouth, OR.

Videos and Presentations

Virtual Adaptive Ag Water Symposium: 3 Presentations recorded on November 6th 2020 - As Oregon and other western states deal with drier growing seasons and higher wildfire risks, it is critical to increase our knowledge of how to grow more food with less water, design for enhanced water retention and infiltration, understand the future of water law in Oregon, as well as how to protect farms and crops using green fire breaks.

2020 Virtual Dry Farm Field Day Tours - The 2020 Dry Farm Project field tours were held on Wednesday mornings in August and September of 2020 There were nine field tours featuring different elements of the five core projects; Tomatoes, Corn Breeding, Soil Management, Solar Co-location with Dry-Farmed Vegetables, and Variety Trials. 

Growing Resilience: Water Management Workshop Series - This workshop series, funded by an Oregon SARE Mini-Grant, focused on drought mitigation tools and management practices for farming with little or no irrigation. Videos and course materials from this series  are available free online.
