    Buckwheat is not likely to increase soil organic matter content much because dry matter production is relatively low and tissues are succulent and decompose very rapidly when incorporated. However, buckwheat can im ...
  • Cereal rye (Secale cereale L.) 
    Oregon State University. Extension Service; Sattell, Robert; Dick, Richard; Karow, Russell S.; Kaufman, Diane; Hemphill, Delbert D.; Luna, John; McGrath, Daniel M. (Daniel Morton) (Corvallis, Or. : Extension Service, Oregon State University, 1998-01)
    Cereal rye is an erect annual grass with greenish blue, flat blades and an extensive fibrous root system. It resembles wheat, but usually is taller (3–5 ft) and tillers less. Flowering is induced by 14 hours of ligh ...
  • Columbia root-knot nematode control in potato : using crop rotations and cover crops 
    Oregon State University. Extension Service; Ingham, Russ; Dick, Richard; Sattell, Robert (Corvallis, Or. : Extension Service, Oregon State University, 1999-11)
    Traditionally, M. chitwoodi is controlled with chemical nematicides, many of which risk suspension for use on potatoes due to health and environmental concerns. It is essential to develop and refine alternative strat ...
  • Common vetch (Vicia sativa L.) 
    Oregon State University. Extension Service; Sattell, Robert; Dick, Richard; Luna, John; McGrath, Daniel M. (Daniel Morton); Peachey, Ronald Edward (Corvallis, Or. : Extension Service, Oregon State University, 1998-01)
    Common vetch is a viny, succulent, annual legume attaining a height of 24 inches when planted alone. It grows taller when planted with a tall companion crop that provides structural support for climbing.
  • Cover crop dry matter and nitrogen accumulation in Western Oregon 
    Oregon State University. Extension Service; Sattell, Robert; Buford, Thomas; Murray, Helene; Dick, Richard; McGrath, Daniel M. (Daniel Morton) (Corvallis, Or. : Extension Service, Oregon State University, 1999-10)
    Cover crop selection and management depend on many factors, among them the cover crop’s ability to accumulate dry matter (i.e., residues) and nitrogen (N). Dry matter provides energy for soil organisms, contributes ...
  • Cover crop weed suppression in annual rotations 
    Oregon State University. Extension Service; Peachey, Ronald Edward; Luna, John; Dick, Richard; Sattell, Robert (Corvallis, Or. : Extension Service, Oregon State University, 1999-10)
    Weed suppression varies with cover crop type and management, residue and tillage management, and weed populations.
  • Crimson clover (Trifolium incarnatum L.) 
    Oregon State University. Extension Service; Sattell, Robert; Dick, Richard; Hemphill, Delbert D.; Luna, John; McGrath, Daniel M. (Daniel Morton) (Corvallis, Or. : Extension Service, Oregon State University, 1998-01)
    Crimson clover may be used as a cover crop, green manure, pasture, or hay. It often is used as a winter annual cover crop in annual rotations. It has been used successfully in reduced-tillage farming systems, and i ...

  • Field evaluation of passive capillary samplers in monitoring the leaching of agrochemicals 
    Brandi-Dohrn, Florian M. (1993-11-17)
    Soil solution samplers have certain inadequacies that limit their range of possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the soil pore-water via a fiber glass wick, have shown promis ...
  • Field pea (Pisum sativum L. or Pisum sativum L. ssp. arvense (L.) Poir.
