PULMAN – Andy McGuire, WSU Extension’s Lauzier Agricultural Systems Educator at Ephrata,received a $50,000 grant to research and demonstration work on high-residue farming systems.

The grant is provided by the Paul Lauzier Charitable Foundation. It will be used to purchase a center pivot sprinkler irrigation system, WSU’s Othello Research Unit, this summer.

High-residue farming is a system of practices, including minimum tillage and direct seeding, that maintains a cover of living or dead plants on the soil to conserve soil and moisture.

Over time, such practices can improve soil quality and result in savings of fuel, reduced wind erosion, labor and equipment costs, according to McGuire.

In fact, wind erosion prevention is attracting interest in irrigated farming regions in the Columbia Basin. “We can have a problem with spring wind erosion in areas that have sandy soils,” McGuire said “Farmers worry about their crop blowing out in the spring, and we’ve seen a lot of high winds this year.”

High-residue farming has been used in the Midwest for many years, but the farming techniques practiced there must be adapted to the irrigated Columbia Basin.

“It’s done a lot in the Midwest, but not under irrigation systems and not in the complicated rotations that we have here,” McGuire said. “We don’t depend on rainfall so much as they do, and we grow a lot more than corn and soybeans, so we have to figure out how to fit different crops in rotation using these systems.”


McGuire has been conducting demonstrations on leased land. Moving the demonstrations to Othello will enable him to conduct longer term research and provide one location where farmers can come to see the farming technology in use.

“I don’t think any farmers are going to make investments in the kind of machinery they will need without seeing how it works and seeing some of the benefits,” McGuire said.
