The Agricultural Systems program focuses on designing and assessing whole agricultural systems and their key components. This research uses field trials and monitoring in conjunction with modeling to explain and improve our understanding of system functions and impacts. Many of our projects compare and characterize alternative systems or components in order to provide information to guide the evolution of agriculture toward improved efficiency, productivity, and sustainability.
My research group measures, models and explains the spatial variability of soil properties and processes with applications to precision agriculture and phenomics. We make extensive use of GIS, remote sensing, digital terrain modeling, spatial statistics, and soil sensors.
My current research focuses on water availability to plant processes in the soil/plant/atmosphere and its role in plant species progression and dormancy along with water conservation. Paramount to this effort is the conversion of sensor measurements to actionable information, so these projects include interdisciplinary collaboration between ecology, agriculture, environmental biophysics, and bioinformatics. The goal of this work is to provide stakeholders with better understanding upon which to base critical environmental decision-making.
I conduct research in sustainable and organic agriculture, with an emphasis on biological soil fertility. Current project areas include life cycle analysis of farming, management for soil health, mycorrhizal colonization of alternative crops, acid-tolerant rhizobia, and compost tea.
Steve Fransen continues to work with perennial warm-season grasses as biofuel and forage utilization. A larger USDA funded study will be completed in 2016 involving intercropping switchgrass cultivars into stands of hybrid poplar at GreenWood Resources at Boardman, OR. We found higher land equivalent ratios (LER) through intercropping than growing trees or grass in monoculture. Recently winter canola is part of his research focus with several studies focused on dual-purpose, forage and seed, use of August planted winter canola under irrigation. So far we’ve found greater economic return when managing winter canola for dual-purpose even through grain yields were lower than monoculture grain production. These studies will continue through 2017.
I specialize in the sociology of agriculture and food systems. My research focuses primarily on agricultural knowledge, science, and technology. I am interested in the sources of agricultural knowledge; the adoption and diffusion of agricultural innovations; and the ways in which agricultural beliefs, choices, and practices affect community well-being, sustainability, rural quality of life, food security, and the environment.
Dave Huggins is Director of the Cook Agronomy Farm Long-Term Agroecosystem Research (LTAR) site and Co-Director of the Pacific Northwest Climate Hub. His research is in the area of Conservation Farming and Agroecology focusing on nitrogen use efficiency, carbon sequestration and overall agroecosystem performance.
My program, the Sustainable Seed Systems Lab, is focused on the breeding and agronomy of barley, quinoa, millet, spelt, and perennial wheat. We work closely with farmers on regional to international scales to develop high yielding, nutritionally dense seed crop varieties for a diversity of cropping systems.
I conduct work at the interface between crops and soils at rhizosphere and cropping systems levels the Nutrient Cycling and Rhizosphere Ecology Analytics, Technology and Education (NCREATE) team. We digitally image root rhizospheres and we track nutrient use and cycling of crops in rotations to better inform nutrient management recommendations, which we extend to student and farming communities.
My research utilizes on-farm techniques for assessing the sustainability of contrasting farming systems. I have successfully measured the sustainability of alternative (biodynamic, integrated, no-till, organic, and perennial-grain) and conventional farming systems on more than 100 farms on four continents. Sustainability indicators measured include soil quality, productivity, financial performance, environmental quality, and social wellbeing.
My cropping systems research and extension program is mainly focused in low-precipitation (less than 12 inch annual) farming areas. Research interests include: best management practices to reduce wind erosion, increased cropping intensity, alternative crops, and water use efficiency in cropping systems.
My research focuses on soil fertility and best nutrient management practices for optimum crop yield and economic returns, while aware of environmental concerns.
