Irrigated Ag Information Service

A new WSU Extension website for agricultural industry professionals is designed to provide users with a customizable source of timely information on all aspects of irrigated agriculture. The service is completely free and was developed by a team of WSU Extension irrigation and agronomy experts.

Mustard Types, Seed Sources & Acreage Estimates

Types of mustard for green manures, contacts for WA seed and estimates for mustard acreage by year.

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.

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.

The Effects of Reducing Tillage on Pest Management

Andy McGuire, WSU Extension. 2007. An increasing number of farmers in the Columbia Basin are adapting reduced tillage systems from other regions to our conditions and crops. This paper will examine the general effects of reducing tillage on the management of weeds, insects, and diseases. Because these systems have been developed mainly in the Midwest and Canada, much of the information presented here is for the conditions and crops (mainly corn and wheat) in those regions. Experience will show what holds true under our conditions.
