Tracking the Tango Between Tillage, Soil Health, and Weeds

Tillage is a crucial stage in annual agricultural systems that terminates overwintering vegetation, incorporates plant residues, and prepares the soil for crops. These activities degrade soil health and impact indicators such as soil microbial biomass, organic matter, and aggregate stability. Weed populations are also influenced by tillage as seed and vegetative parts are horizontally and […]

Rotating out of weeds and into soil health: Optimizing cover crops in three Columbia Basin organic production systems

Weeds cause extensive loss in agricultural production and are particularly damaging in organic systems. Control generally relies on mechanical cultivation which reduces soil carbon, decimates soil fauna, and increases erosion potential. Cover cropping, a biologically intensive practice, can be an effective tool to reduce weed pressure and improve soil quality, but it also introduces new […]

Impact of manure-derived fertilizers on bacterial community and antibiotic resistance genes in Washington red raspberry fields

Washington State is the number one producer of processed red raspberries in the nation. Raspberry growers in Whatcom County rely on dairy manure as a ready source to improve soil health prior to planting. Soil is a dynamic entity harboring billions of microorganisms and plays a crucial role in plant production. The microbial quality of […]

Introducing Organic Quinoa Production Systems in the Palouse

The popularity of quinoa in the past decade has quadrupled prices at U.S. retail outlets. For all this demand, the vast majority of the quinoa consumed in the U.S. is imported from Peru, Bolivia, and Ecuador, with 65% of the quinoa sold in the U.S. being organic. This project hopes to increase organic quinoa production […]

Developing adapted varieties and optimal management practices for quinoa in diverse environments across Washington State

Quinoa is a highly nutritious and broadly adapted grain crop in high demand in the US and particularly in the Pacific Northwest region. However, very little is known about appropriate varieties and farming practices, including irrigation needs, fertility requirements and potential intercropping strategies to help control weeds and provide supplemental nitrogen. Our project would primarily […]

Developing Improved Management Practices to Overcome Soil Health Issues in Red Raspberries

This planning grant proposal will bring together researchers from three states (WA, OR, CA) and British Columbia that work in small fruit production (red raspberries focus) from a diverse set of disciplines (pest, nutrient and cultural management) to develop improved integrated practices for red raspberries. Our first actions are to bring together these collaborators to […]

Choosing and managing cover crops to improve weed management in reduced tillage organic vegetable production

Reduced tillage can improve soil quality and reduce fossil fuel use. Adopting reduced tillage in organic production poses challenges because farmers rely on tillage as a primary means of weed management and for incorporating soil amendments to maintain soil fertility and quality. Recent research on organic reduced tillage has focused on mechanically terminated and mulched […]

Tillage reduction and cover cropping for enhanced soil quality and weed management in western Washington organic vegetable farms (OREI)

Organic vegetable growers in western Washington pass over their fields 10 to 20 times annually with tillage equipment ranging from spring tooth harrows to mold board plows. Soil preparation activities such as plowing, rototilling, and even spading pulverize large‐bodied soil organisms and reduce soil carbon storage and aggregates. Successful reduced tillage in organic agriculture relies […]

Alternative Forage and Fodder Crops for Livestock Production

Increased costs of feed and the desire to enhance on-farm livestock feed production have created a need for alternative fodder and forage crops. Historically, many crops such as fodder beets, swedes, carrots and kale were used for livestock feed. Many small-scale crop producers in western Washington are looking to diversify their farming operations to include […]
