About Dry Farming Project...

It is important to note that dry farming is not a new way of farming, but knowledge sharing has been limited because practices have primarily been passed down from farmer to farmer. Compounded by the fact that there is only a very small subset of farmers that experiment with dry farming and an even smaller number have extensive experience in these farming practices, the OSU Extension Dry Farm Project plans to explore, revive, and expand awareness of dry farming.

The Dry Farming Project began in 2013 with case studies of farms in Western Oregon (Garrett 2013; Garrett 2014) and Northern California (coordinated by Community Alliance with Family Farmers) that dry farm a variety of fruit and vegetable crops. These case studies revealed a suite of management practices that support crop production without supplemental irrigation including: careful timing of tillage, keeping soil surface loose to conserve moisture in the root zone (also know as dirt or dust mulch), improving soil quality and water retention with organic matter addition (cover crops, compost, rotational grazing), increased plant spacing, and use of drought-resistant varieties.

There have been dry demonstrations in Western Oregon every year since 2015 (learn more about dry farming demonstrations)

In 2016 the Dry Farming Project expanded to include:

  1. Three dry farming demonstration and field days at OSU Extension research locations in Western Oregon.
  2. Ten on-farm trials throughout Western Oregon.
  3. Growing Resilience: Water Management Workshop Series (funded in part by Western SARE) was organized to increase our knowledge and awareness of how Oregon growers are being affected by drought, expand our toolbox of drought mitigation tools and strategies, and educate agricultural producers and professionals about management practices and strategies for farming with little or no irrigation.
  4. Dry Farming Collaborative - a group of farmers, extension educators, plant breeders, and agricultural professionals partnering to increase knowledge and awareness of dry farming management practices with a hands-on participatory approach. The original function of the DFC was to facilitate farmer-to-farmer information sharing as growers started to experiment and establish their own dry farming trials

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.

Extension Publications

Dryland Farming in the Northwestern United States: A Non-technical Overview - This publication  discusses and describes the process of dryland grain farming, specifically in the Pacific Northwest.

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.

Videos and Presentations

OSU Extension 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 aterials from this series  are available free online.

Dry Farming Collaborative

Initiated in the spring of 2016, we are a group of growers, extension educators, plant breeders, and agricultural professionals partnering to increase knowledge and awareness of dry farming management practices with a hands-on participatory approach. 

The Dry Farming Collaborative (DFC) is exploring what crop varietals perform well dry farmed in our bioregion. All of the crop varietals selected for replication in 2017 were grown at the OSU Lewis Brown Research Farm. In addition, there are 30 DFC sites throughout Western Oregon and Washington that hosted dry farming trials. The DFC selected which crop varietals they wanted to grow for our replicated trials and many also conducted experimental trials of their own. To see what crops were grown for our 2017 DFC Replicated Variety Trials click here.

Three DFC sites will be hosting field days this summer! Participants will learn about dry farming, see crops (tomatoes, squash, melon, zucchini, dry beans, corn, orchard crops) grown with little or no supplemental irrigation in the field. More info and registration coming soon!

2016 Dry Farming Demonstration Report

2015 Demonstrations

Dry Farming Demonstration launched in 2015 in Corvallis

In 2015, three 10’ x 100’ plots were established at Oak Creek Center for Urban Horticulture (OCCUH) to demonstrate dry farming management practices in several crops including dry beans, tomatoes, potatoes, squash and melon. Varieties and management practices were selected based on interviews with several established growers experienced in dry farming. Absolutely no irrigation was applied to these plots.

This project is funded in part by the National Institutes of Food and Agriculture under the Beginning Farmer and Rancher Development Program.

See articles on this dry farming demonstration in the Capital Press as well as the 2015 Summer edition of Oregon Small Farm News!


2015 Dry Farming Field Day

A Dry Farming Field Day was held on August 3, 2015 at the Oak Creek Center for Urban Horticulture (844 SW 35th St.) in Corvallis, Oregon. More than a hundred farmers and gardeners attended to learn more about growing without irrigation and do taste comparisons of dry farmed and irrigated melons and tomatoes.

Summary and Resource Sheet for 2015 Dry Farming Demo - Includes varieties, planting date, plant spacing, harvest date, some preliminary yeild data, and soil preparation description for 2015 Dry Farming Demonstration plots.
