High Residue Farming under Irrigation – Workshops

Digests and agendas from yearly WSU Extension High Residue Farming under Irrigation workshops in Moses Lake, Washington. 2004 to present.

High Residue Farming under Irrigation: Strip-till

Extension Bulletin EM036E. Strip-tillage is a low-impact cultivation technique suited to irrigated land with a lot of residue from a previous crop. A strip-till system creates both clean-till and high-residue conditions in the same field, taking advantage of both systems while minimizing drawbacks. This publication discusses the benefits of this system, as well as equipment needed, general management concerns, and how to get started. A budget is also included to help growers determine the relative net cost of implementing this system.

Closing the recycling loop through organic amendments in agriculture and gardens

Recorded webinar (online presentation) from Jan 2011 by Craig Cogger, Crop and Soils Scientist and Extension Educator. This seminar discusses research and guidelines on soil amendment choices based on use, nitrogen availability, carbon sequestration potential, handling nutrient imbalances in organic amendments, and an update on herbicide issues in some composts.

Agriculture of the Middle external resource

This national initiative seeks to renew what is being called the “agriculture-of-the-middle.” This term refers to a disappearing sector of mid-scale farms/ranches and related agrifood enterprises that are unable to successfully market bulk commodities or sell food directly to consumers. Begun as a task force in 2003, the initiative is entering a development phase.

Mustard Green Manures

On-farm research has been conducted since 1999 to determine the benefits of mustard green manures and to improve their effectiveness. They are being used in irrigated regions of Eastern Washington to improve soil quality, control wind erosion, and manage soilborne pests.

Mustard Varieties for Green Manuring

Choosing mustard varieties and on-farm research results on variety biomass measurements and glucosinolate concentrations and production.

Beefing Up the Palouse

Since 1985 the U.S. government has implemented the Conservation Reserve Program (CRP) which pays farmers NOT to grow crops on millions of acres of highly erodable land. In addition to being a controversial program, much of this land is now coming out of CRP which puts pressure on farmers to grow crops in these areas once again. In the Palouse in Washington State, local farmers and ranchers are looking at holistically grazing livestock as an economically and environmentally sustainable alternative to traditional wheat farming in these sensitive areas and to the CRP in general. Video presented by Managing Change Northwest.
