WSU, a Land Grant College, is dedicated to agriculture production in Washington State. And agriculture, primarily dry-land wheat and barley production, is the primary industry in the Lincoln and East Adams County Area. WSU Faculty and specialists work together to solve agronomic issues, providing education and information on innovative crop production methods, pest identification and management, new seed varieties, to local producers through field tours, workshops, seminars, and pesticide courses. See menu links for categories of information.

Low Soil pH: To Lime or Not to Lime

In the PNW, the average pH in the top 12 inches of soil declined from near neutral to lower than 5.7 by 1984 after years of nitrogen fertilizer applications. Soil pH further declined to lower than 5.2 by 1995, after another 10 years nitrogen fertilizer application. A soil survey conducted by Paul Carter (WSU) in 2014 found that 97% of surveyed minimum and no-till wheat fields in the Columbia County had a soil pH lower than 5.0 at 3-6 inch (seed/rooting zone) soil depths. Similar survey numbers have been observed in many areas across the eastern Washington dryland crop production areas. The soil pH will continue to decline as a result of continued nitrogen fertilizer applications if no mitigation actions are taken to reverse the acidification process. In fact, our recent survey found that many grower fields or areas of fields have pH values as low as 4.0. Some farmers in Montana have reported extremely low soil pH on their farms and those fields are no longer suitable for some crop production.

2017 WSU Weed Control Report Now Available

Weeds are the bane of many a farmers’ existences in eastern Washington. It seems we are in a constant battle to keep weeds under control. As part of that effort, WSU weed scientists, Drew Lyon and Ian Burke, manage numerous field studies to evaluate new herbicides, and new uses of older herbicides to manage weeds of concern to dryland farmers in eastern Washington. These studies are summarized in the annual WSU Weed Control Report.

Residue Yield Calculator is Now Online

Crop residue is a valuable by-product in crop production. Leaving adequate amounts of residue on agriculture fields can effectively control soil erosion and improve soil health. Crop residue can also be used as a feedstock for biofuel, paper, or mushroom production and as feed and bedding for livestock.

Estimating how much crop residue your crop can produce is important for understanding how the residue can be used to add economic or ecological benefits to your farm’s operation. Unlike estimating grain yield, which is typically measured directly through yield monitoring, residue production is generally estimated indirectly based on grain yield.

Seeding Rate Converter is Online

Seeding rate is among the many factors that affect grain yield that can be controlled. The ability to control seeding rate allows farmers flexibility in their management practices. For example, when fall seeding is delayed the tillering period is shortened. To compensate for this reduction in fall tillers, farmers can increase seeding rates.

To some extent, wheat is inherently capable of compensating for factors that influence yield. However, optimum seeding rate are required to optimize the plant population, which in turn is important for maximizing grain yield and quality and controlling weeds.

Seeding rates are typically expressed as seeds per acre or pounds per acre. Determining seeding rates using pounds per acre is problematic because MORE on

 Weed Control Report

The 2016 WSU Weed Control Report is now available on the Wheat and Small Grains website. The annual report summarizes the results from field studies conducted by Ian Burke, Drew Lyon, and their staff. The research was conducted in winter wheat, spring wheat, chemical fallow, grasslands, alfalfa, chickpeas, and dry pea
