At present the adsorption kinetic of ions by soil particles is considered to be a surface reaction. When the transport of solutes in soils is described using the one-dimensional flow equation, it becomes a serious problem that lateral diffusion of ions from the bulk solution towards the soil surfaces is...
CTSPAC is a mathematical model for coupled transport of water, solutes, and thermal
energy in the soil-plant-atmosphere continuum. The mathematical structure consists
of coupling a model for transport through soil (soil submodel) to one for xylem and phloem
transport (plant submodel). The modeling approach is based on discrete space conceptualization...

This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
Time of stand establishment is a critical factor affecting
yields of winter wheat and barley in the fallow-crop rotation areas
of the Pacific Northwest. Farmers in this winter-rainfall region
are dependent on residual moisture in the seed zone for germination,
because significant precipitation does not usually occur until
after the...
