New from Extension: Better silage through intercropping

Corn–soybean intercropping at WSU’s IAREC research center, Prosser.

The latest free guide from WSU Extension informs dairy feed growers of the potential benefits of intercropping—specifically, introducing forage soybean into a corn-triticale system.

WSU authors Steve Norberg, Don Llewellyn, and Steve Fransen, with Sandya Kesoju of Columbia Basin College, explore the economic and nutrient gains of pairing soy with corn. Their project was encouraged by the Washington State Dairy Federation and financially supported by WSU.

Intercropping is an old-established practice of cultivating two or more crops in the same field simultaneously. Double cropping a corn–triticale rotation for silage is a common practice in the Columbia Basin and other parts of the northwest, because it increases the amount of feed that can be grown.
