John Williams

Educational Background:

I completed my BA in biology in 1986 and my MS in rangeland resources in 1988 at Oregon State University. I completed my PhD in range science at Utah State University in 1993.

Research Program: Hydrology

Hydrology and soil conservation in dry-land crop and biofuel production systems.

Current Research Projects:

  • Identify the optimal timing for creation of a reduced tillage fallow mulch in the lower precipitation (<350 mm) winter wheat-fallow region and determine if it can be predicted using soil water, temperature, or weather forecasts, and if it is different from the timing farmer already use.
  • Predict where early seeding is not necessary from maps of growing degree days following fall precipitation.
  • Determine the effect of crop sequences with oil seed crops on overwinter infiltration, rain capture, and soil water storage for spring crops.
  • Calibrate and use the SWAT model to determine potential changes in crop productivity, hydrology, and sediment loads resulting from a shift from conventional to diverse cropping systems.

Other Research Interests:

  • Biofuel production potential of perennial riparian buffers in agricultural landscapes
    Federal conservation programs have the potential to provide conservation services and crops bioenergy, particularly where conservation buffers are installed. I recently completed research evaluating the potential of using conservation buffers as sources of lignocellulosic feedstocks for biofuels. Much of the riparian area formally incorporated into crop production on the Columbia Plateau are has been enrolled in conservation buffer programs. These areas are intrinsically productive, if not specifically for small grain production. The data from this project demonstrates the productivity of perennial species used in conservation buffers and the opportunity to diversify wheat-based cropping systems while providing biomass for energy production and/or forage.
