Seed Science and Technology

Seed quality evaluation in relation to the physiology of seed germination, vigor, dormancy, storability, post-harvest technologies, and the relationship to field performance. Accepts only self-funded graduate students.

Cereal Variety Testing
My program's priority is to conduct wheat and barley variety trials across major cereal producing regions in Oregon. Each year, wheat and barley varieties from public and private plant breeding programs are tested in 25 locations across Oregon, as...

Forage Program Director with research, teaching, extension, and international activities focused on matching forage species to locations based on climate, soils, intended use, and management and alfalfa crop simulation modeling. Undergraduate and graduate teaching and student advising. State,...

• Long-term effects of agricultural practices on production systems
• Hemp, oilseeds, essential oil and medicinal plants, plant chemicals
• Utilization of plant chemicals as alternatives to synthetic plant hormones, growth regulators, and pesticides
• ...

The processes at the interface between organic matter and mineral surfaces, including mineral surface properties, organic matter properties, bonding mechanisms, adsorption processes, mineral-microbial interactions, and organic matter turnover dynamics.

Projects:...

Nutrient cycling in natural and human-disturbed ecosystems, including the attenuation of increased nitrogen inputs to terrestrial ecosystems by soils and vegetation, detrital controls on soil organic matter formation.

I am not accepting new graduate students at this time.

I teach classes for the Sustainability Double-Degree Program and the Department of Horticulture - both on the Corvallis campus and through Ecampus.  My instructional duties also include coordination of service-learning projects for large undergraduate courses (SOIL 205, SUS 350, and SUS 304...

Stephen Machado leads the OSU's long-term research activities at CBARC Pendleton, CBARC Moro, and in Heppner in eastern Oregon. He is the Dryland Cropping Systems Agronomist for the semiarid Northcentral and Northeast Oregon. His responsibilities include establishing research priorities,...

• Soil health (fertility and nutrient cycling)
• Crop production systems (industrial hemp, small grain, forages)
• Environment (soil and water protection)
• Climate Smart Agriculture (biochar, greenhouse gas emissions)

I develop and teach Soils courses in the Crop and Soil Science Department, both on the Corvallis campus and via Ecampus.

My applied research and extension program focuses on developing practical, science-based solutions to weed management challenges in Oregon field crops. My research interests include herbicide resistance, herbicide fate in the environment and non-target impacts, integrated weed management, and...

Research interests include crop water use, irrigation, water and chemical movement through soil, macropore flow, water quality, and alternative crop evaluation and management in a semi-arid climate.

The Aroma Hop Breeding Program is tasked with developing new hop cultivars, adapted for Oregon growing conditions, with a focus on essential oil quality. This program interacts closely with Dr. Tom Shellhammer's program in the Food Science & Technology Department to characterize the...

Extension Agronomist with field crop responsibilities in Union, Baker, and Wallowa Co.

Focused on dryland cropping systems, soil, water and nutrient management, soil erosion, soil quality, and rotational crops.

Research projects are concerned with improving management of soils under dryland farming systems in relation to soil and water conservation, crop rotation, nutrient...
